Porto Lagos, dry sandy places, 23 May 1930, H. G. Tedd 334. An account of the synonymy and specific history of Silene subconica Friv. has been published in Kew Bull. 1933, 40. It is there shown that S. juvenalis Del. is a synonym of this species, which — apart from occurrences as an alien — has a distribution from S.E. Italy, through Greece, Thessaly, N. and S. Macedonia, Thrace, N. and S. Bulgaria, the Rodope Massif, Dobruja, Serbia, Hercegovina, and Asia Minor, east to Armenia. The supposed long dormancy of the seeds under the old scoriae from the silver mines at Laurion is also considered and refuted. The plant figured is a somewhat striking and apparently well-defined, though rather local, variation from S. subconica which, as described by Frivaldszky, is found with a fairly general distribution in the countries round the north of the Aegean Sea and extending east, north 2 and west from there. Davidoff collected his material from near Dedeagach, Maori, and Porto-Lagos. He remarks that the variety flowers 10 to 15 days later than the typical kind, and is met with in small communities along the sands of the Aegean in western Thrace. It seems very probable that the variety arose mutationally in this area. Flower mutations involving petal size, recessive to the normal, so far as tested, are known for S. maritima and add to the poly¬ morphism of that species. It is of interest to record that a variation very similar to that of S. subconica var. Grisebachii has appeared in one plant in a large generation of S. vulgaris s.l. (probably a segregate from S. glareosa X S. vulgaris s.s.), grown in the Herbarium Ground, Kew, from seed collected by the writer on 7 Aug. 1931, above St. Nizier, Hautes Alpes, France. Material is preserved at Kew under the number K.1099, Plant 4. The character will, it is hoped, be studied genetically, and its “ parallel ” occurrence in another species is alone noted here. Davidoff’s statement that his specimens are provided with “ carpo- phoro longiore (vix 2 mm.) ” needs further elucidation. In our material the true gynophore (carpophore) in the flowering condition is 2 to 2*5 mm. long, but the apparent gynophore, i.e. from the base of the calyx and thus including the calyx invagination and the very tightly fitting “ corolla-tube/’ is quite 4 mm. long. It is probably the develop¬ ment of the internode, if such it be, between the calyx and corolla and the corresponding elongation of the true gynophore which causes the protrusion of the petals beyond the calyx teeth. Detailed inves¬ tigation must await the receipt of material suitable for anatomical examination. — W. B. Turrill.

In addition to the records of specimens cited above, all in the Kew Herbarium, the following are important : “ In regione montana Macedoniae occidentalis ; in m. Nidg<$, cum Junipero Oxycedro , alt. 2650/-3000/ (substr. marmor.) ! ; inter Trojaz-chan et Perlepe (substr. calc.) (Friedr.). FI. Jun. E.” (Griseb. l.c.) ; “ In regione superiore mt. Ossa Thessaliae ” (Hal. Consp. Flor. Graec. i. 431 : 1900) ; Pletvar in M. (Vandas, Reliq. Formanek. 172 : 1909). It may be noted that Perlepe is another name for Prilip, that Trojaci is a village lOi miles to the east of Prilip, and Pletvar a place 5 miles to the east of Prilip. It is probable that Grisebach’s specimen written up “ Scardus ” in the Kew Herbarium is not from Scardus proper, i.e. the Shar Planina, but is a type specimen from “ m. Nidge.” In his Reise durch Rumelien, ii. 164 (1841), Grisebach lists his Astragalus sericophyllus as collected on 28 June 1839, between 2650 and 3000 ft., above Zejjen. In tracing Grisebach’s route for this part of his journey it appears probable that he crossed the Malka Nidge and not the higher range of the Nidge proper to the north-east. It is evident that the species may be expected to occur on mountains between those of South Macedonia and Attica. The record for Mt. Ossa indicates an intermediate station, but no specimen from Thessaly has been seen. A certain range of variation is apparent in the available material, more especially in the shape of the leaflets. These are relatively long and narrow in the specimens under Alston and Sandwith 909, and relatively short and broad in those under Atchley 1600. The remaining specimens are more or less intermediate in this respect. The proportion of white to black hairs on the calyces and the extent to which they are adpressed also show some variation. Alston and Sandwith describe the flowers of their No. 867 as “ reddish-purple ” and of their No. 909 as “ standard mauve ; keel and wings whitish.” — W. B. Turrill.

Myrtus communis L. has been recognized from ancient times to be a polymorphic species, and it is of interest that some of its variations, including that figured here, can be traced back in literature to a period nearly two thousand years ago. The variety tarentina is primarily distinguished from other varieties by the smaller and narrower leaves. All specimens examined which have been definitely placed in this variety have also a fine thick indu¬ mentum on the young branches. This character, however, is not limited to var. tarentina , being seen in other specimens, preserved at 2 Kew, with leaves of or approximating to the average shape and size for the species. The pedicels are on the whole shorter and the flowers slightly smaller than in the more usual varieties, but no constant characters, limited to the variety, have been found in the shape of the calyx segments or fruits, although it should be noted that little fruiting material is available for study. Structures intermediate between sepals and petals, and between petals and stamens, have been observed in cultivated material. The internodes are frequently rather short, giving the leaves a crowded appearance. There is in some specimens a tendency for the leaves, especially in the flowering parts of the branches, to lose their definite opposite decussate arrangement. Plants seen by the writer in Dalmatia were somewhat smaller than most of those of the commoner kind. It is difficult to speak with certainty of the natural distribution of the variety, partly because of the paucity of herbarium material and partly because it has been widely cultivated. It occurs here and there in the macchia on the Dalmatian coast, mixed with specimens of the broader-leaved variety, having been found, for example, near sea- level on the island of Lacroma, in 1925 (Turrill 1062). In Italy it is recorded from near Taranto and from the Naples district. For Sicily, Pojero, FI. Sicula, i. pt. 2, 225 (1891), says “ La var. tarentina la cito solo per farsene ricerca in Sicilia, ove non dovrebbe mancare.” Moris, FI. Sardoa, ii. 79 (1840), records the variety in Sardinia as growing “ in aridis circa S. Rocco di Pula,” but also says “ Varietas tarentina , in hortis cultura persistens, alienam a vulgari stirpe faciem refert. Sed stipites ejus, in statu naturae folia ramea inferiora identidem promunt ut in varietate vulgari , praeterea occurrunt foliis baccisque minoribus majoribusve quibus ad typum accedent.” Rouy and Foucaud (l.c.) record our plant from various localities in the Bouches-du-Rhone, Aude, and Corsica. It is doubtful if the variety occurs wild in Spain. Laguna, FI. For. Espan. 153, t. 9 (1872), says it is cultivated at Granada and (probably) in Cataluna at S. Miguel del Fay. In the herbarium of the British Museum (Natural History) there is" a specimen from Cataluna (Monroig, garigues de Miramar, 1917 — iv et vii, F. Sennen — Plantes d’Espagne 3052), under the name Myrtus Borbonis Sennen, which is indistinguishable from M. communis var. tarentina . The var. microphylla \V illk. et Lange, Prodr. FI. Hisp. iii. 191 (1874), is most probably a different variety from var. tarentina . Lowe, Manual FI. Madeira, 268 (1868), says that var. tarentina occurs frequently in gardens. A specimen in Herb. Kew. collected in Teneriffe (in rupibus siccis Metceca, Aug. 1845, Bourgeau 513) shows that the plant is known from the Canaries, but probably only as an escape from cultivation. The varietal name “tarentina” was taken over by Linnaeus (Sp. PI. 47 J : 1753) from C. Bauhin (Pinax 469: 1623), and by C. Bauhin from Mattioli (Comment. ed.Bauh. 196: 1598). Linnaeus’s reference is simply “y Myrtus minor vulgaris. Bauh. pin. 469.” Fortunately in Mattioli, l.c. 195, under the title “ II. Myrtus Tarentina,” there is an excellent figure which enables the variety to be fixed without doubt. The text 3 no * comments on the plant are “ Quod Dioscoridi Myrtidanum nominatur, vulgo notissimum est, ubi scilicet myrtus frequens nascitur. Sunt et alia veteribus Myrti genera, nobis quoque non ignota, nempe Tarentinum, et exoticum. Tarentina a Tarento Apuliae civitate, ubi copiosa provenit ita vocata, folio est nostrate longe minutiore, robustio- reque : fructu minore, copiosiore, et in summitate pluribus apicibus coronato, colore ex nigro purpurascente, minutis, crebris, albicanti- busque intus ossiculis : floribus communi Myrto similibus.,, This description is, in part, the same as that in Dalechamps, Hist. Gen. 237-38 (1587)— where (on p. 237) there is also a good figure of our plant under the name Myrtus Tarentina — and is evidently derived from Mattioli’s Comment, ed. 1565, p. 232 (figure on p.229). This figure is similar to, but not the same as, that in Bauhin’s edition, but is a reproduction of that in Mattioli, New Kreiiterbuch, 81 (1563). On p. 80 of this work the following words occur : “ Es sindt auch noch andere geschlecht bey den alten erfunden, nemlich bey dem Plinio lib. 15. cap. 29. der erzelet noch Myrtum Tarentinam, und Exoticam. Myrtus Tarentina, allso genandt von der herrlichen stadt Apuliae, hat vil kleiner und steiffer Blotter dann der einheymische. Auch runder und kleiner friichte, die sindt am oberteil gekronet, an der farb schwarz purpur, haben inwendig vil weisse kleinc steinkernlen. Er bliiet wie der gemeine Myrtenbaum.” This reference to the name Myrtus Tarentina most certainly, as indi¬ cated by the description, locality, and figure, refers to the plant here figured. The reference to Pliny, however, allows the variety to be traced back to near the beginning of the Christian era (Pliny: a.d. 23-79). Pliny’s words are : “ Sati varum genera topiarii faciunt : Tarentinam, folio minuto : nostratem, patulo : hexasticham densissimo, senis foliorum versibus,” ed. Harduin. i. 753 (1723). It would seem that Pliny regarded the Tarentine myrtle as a cultivated plant. Be that as it may, it is a matter of considerable interest that the same variety is still in existence after nearly two thousand years. The Tarentine myrtle was also mentioned in Mattioli, Comm. 129 (1554), and the name may occur in other early herbals than those here quoted. In Museum No. I at Kew, specimens of Myrtus communis are pre¬ served from ancient, especially Egyptian, tombs. Material received from Prof, (now Sir) Flinders Petrie, from “ animal burials of Roman age Lahun,” has hairy shoots and leaves smaller than the average for the species, but, in the writer’s opinion the leaf shape is not that of the var. tarentina. The variety is said to be hardier under cultivation in the British Isles than other varieties (see Bean, Trees and Shrubs Hardy in the British Isles, ii. 91 : 1921).— W. B. Turrill.

Apparently in correlation with the long corolla-tube, the stamens have very short filaments and are included in the tube. The affinity of A. amanus is with A. scaber (Boiss. et Heldr.) origin¬ ally described from Mt. Taygetos in the Peloponnese. Orphanides also collected it on Mt. Malevo, Laconia. A. pulcher (Boiss. et Heldr.) Briq., from Mt. Dirphys (Delphi) and Kandyli, Euboea, has usually been regarded as a distinct species. A careful examination of the material now available at Kew has, however, led to the conclusion that it is not specifically distinct from A. scaber . The earliest name for the species as thus accepted is Origanum scabrum Boiss. et Heldr. removed to Amaracus by Briquet in Pflanzenfam. iv. 3A, 306 (1896). Another species showing some morphological affinity with Amaracus amanus is A. cordifolius (Montbr. et Auch.) Benth. from Cyprus (probably the record from Syria is incorrect). This is a much taller plant with broader floral bracts and shorter corollas. The plate and description have been prepared from Haradjian’s material preserved at Kew. President Dodge, of the American University of Beirut, kindly lent the type specimen from Post’s Her¬ barium, and there is no doubt that Haradjian s and Post s material represent the same species. The former has the vegetative parts slightly more hispid, the leaves and bracts less acute, the calyx-teeth slightly broader, and the corolla-tube less hairy than in the type. One of the three pieces of the type sheet has the bracts and calyx-teeth exceptionally narrow, the former being almost acuminate. A. K. Jackson.

It is the most densely hairy species known in this aberrant genus, which differs from all other genera of Campanulaceae in having the ovary wholly superior, and is confined to the interior of Asia. The rather striking habit of the plant is doubt¬ less a response to the conditions under which it grows, where, at an altitude of 12,000 feet, it would be under deep snow in the winter and exposed to the high winds prevalent in Tibet during the comparatively short summer period. — C.

Branches arched. In fruit, fruits black.” This variety is distinguishable by its broader, very definitely cordate leaves, the two lateral nerves of which leave the midrib at the extreme base at an angle of 80°-90° and follow a course practically parallel to the margin. In the type of the species the leaves are rounded-truncate to broadly cuneate at the base (though very slightly cordate in Forrest 9568), and the nerves diverge from the midrib, generally distinctly above the base, at an acute angle (40°-45°). Though inhabiting much the same geographical area as the type, the variety petanoneuron seems to favour higher altitudes : 2400-3000 m. as against 1800-2100 m. The anthers of G. dumicola were originally described as biaristate, but in none of the material examined, either of the typical plant or of the variety, has any sign of appendages been observed ; indeed, in most cases the stamens consist of the minute filament only. Func¬ tionally unisexual flowers are of course known in other species of the genus, but in G. dumicola “ female ” flowers seem to be the rule. H. K. Airy-Shaw.

Flowers cream in bud, banded with red (often) when fully open ; very large.” An investigation into the relationships of the two species of Gaul - thena figured in this and in the preceding plate has shown the necessity for considerable readjustments in the classification of the Asiatic species of the genus. It is hoped to publish elsewhere a paper on this subject. Here it may suffice to observe that the two species now figured, together with G. notabilis Anth. from Yunnan and an un¬ described species from Sumatra, form a natural group which it is proposed to distinguish as follows : — Series Dumicolae Airy-Shaw , ser. nov. Pedicelli ima basi (raro paullo supra basin) bibracteolati, bracteolis haud connatis. Folia infra medium latiora (plus minus ovata). Flores in racemis brevibus corymbosis dispositi. Corolla campanulata. — Typus : G. dumicola W. W. Sm. . It should be pointed out that none of the above characters (with the possible exception of the inflorescence) is actually confined to 3 this group. In combination, however, they clearly delimit the four constituent species from the remainder of the genus. G . codonaniha is readily distinguishable from the two Yunnan species by the very large size of the flowers. The specimens collected by Ward show some variation in indumentum : this may be due to differences of light-intensity in the habitat. G. notabilis Anth. differs from G. dumicola W. W. Sm. in its dwarf habit, slender branches, sparse ferrugineous indumentum, small leaves and few-flowered inflorescences. H. K. Airy-Shaw.

Under the name Mariscopsis hyalinus the present plant formed the I subject of an article by the writer in Kew Bull. 1932, 456. At that] time, however, Domin’s genus Queenslandiella had not been studied! nor, indeed, could it have been surmised that a new genus of Australian] Cyperaceae was identical with a long-established Indian species.] Unfortunately, it has not been found possible to obtain on loan the type] of Queenslandiella mira from Dr. Domin’s herbarium at Prague, and] no authenticated specimen of Queenslandiella exists in the Kew Her-1 barium. There can, however, be no doubt, from the drawing repro-l duced in Bibliotheca Botanica and the very full description thereinj that Domin’s plant is identical with Mariscopsis hyalinus. The extension of the distribution of Queenslandiella to North Queens'] land is not surprising since it had already been recorded from Timor, while distributions similar to that of Queenslandiella are already known for certain grasses. Mr. C. E. Hubbard, who collected in Queensland 1 during 1930-1931, found that in the neighbourhood of Chillagoe, the | type locality of Queenslandiella , many species of grasses occur, of which the following have the same distribution as Queenslandiella : Alloter I op sis cimicina (Retz.) Stapf (Axonopus Maidenianus Domin) ; ErCr grostis pilosa Beauv. ; Imperata cylindrica Beauv. var. Koenigii Dur* | & Schinz ; Eriochloa procera (Retz.) C. E. Hubbard. Of these* Eragrostis pilosa has been introduced to Chillagoe, but the others are probably native. f The introduction of an annual weed such as Queenslandiella is easily understandable when it is remembered that Chillagoe is a mining district | where great quantities of materials of all kinds must have been imported in the past. C. E. Hubbard, when he visited the area twenty ye*** after Domin’s discovery, was unable to find a single plant, although he made a special search for it. 3 The systematic position of the genus has been discussed in Kew Bull. 1932, 457. There seems little doubt that it comes nearest to Kyllinga , which agrees in possessing a biconvex nut and a spikelet which disarticulates in one piece at maturity. In accordance with the rule of priority, the genus must bear the name Queenslandiella in place of Mariscopsis Chermezon. This is somewhat unfortunate, since the plant is undoubtedly Indian in origin. As mentioned in the previous paper, the plant possesses the strong and characteristic odour of Trigonella Foenum-graecum. The same smell occurs also in Cyperus aristatus Rottb., another annual member of the Cyperaceae found in India. — F. Ballard.

Cook District : Badu Island, May 1911, Bick 96 ; Lloyd Bay, April 1886, Gulliver (type). There is no doubt that Cleistochloa is most closely allied to Entolasia Stapf, a genus originally described from tropical Africa and to which Miss D. K. Hughes added two Australian species, E. marginata (R. Br.) Hughes and E . slricta (R. Br.) Hughes. Some Australian species of Entolasia are very similar in habit to Cleistochloa suhjuncea , and in southern localities are found growing with it. No cleistogamous spikelets, however, have been found by me in any species of Entolasia. Cleistochloa suhjuncea probably occurs throughout the greater part of the Dividing Range, the adjacent ranges and their offshoots in Queensland. It is usually abundant in dry localities amongst sand¬ stone or similar rocks and stones on the upper slopes or summits. In such situations the vegetation is open Eucalyptus forest with an under¬ growth of scattered shrubs and isolated tufts of xeromorphic species of Entolasia , Aristida , Eragrostis , Eriachne , etc. It is well adapted to withstand the periods of drought which occur in the area of its dis¬ tribution. The thick wiry roots, which penetrate deeply into the soil or rock-crevices, are covered with a layer of dense root-hairs ; these together with adhering particles of sand provide a protective sheath. The small leaf-blades readily disarticulate from the sheaths, and their work is apparently carried on by the dark green culms. Individual plants present a characteristic bushy appearance due to the much' branched rigid wiry culms. The cleistogamous spikelets are abundantly produced in the axils of almost all the leaf-sheaths, and at maturity largo numbers may be seen on the ground beneath the plants. They are not, however, usually developed in the axil of the terminal leaf-sheath immediately below the inflorescence, but a rudimentary pedicel has been found 5 there in the specimens examined. In the type specimen of Panicum subjunceum, kindly lent by Dr. Domin for examination, the cleisto- gamous spikelets have already fallen, but their pedicels are visible. Several special features are found in the cleistogamous spikelet. The lower gluma is reduced to an obscure rim at the base of the spikelet The sterile lemma in the fresh condition is rather thick with a smooth convex back. At maturity it hardens, the soft tissues become depressed leaving a more or less prominent midrib, two keels and an apical dorsal projection. A scar-like dorsal surface is thus produced which changes in colour from yellow to brown on maturity. This indurated sterile lemma closely embraces the fertile floret and serves to protect the grain In the mature fertile floret the minute anthers are found entangled with the stigmatic hairs at the apex of the caryopsis, the whole being enclosed by the lemma and palea. As the cleistogamous spikelet develops it pushes out the leaf-sheath and causes the culm to assume a slightly bowed appearance, thus permitting the spikelet to fall to the ground at maturity. In Cleistochloa subjuncea the cleistogamous spikelets are probably produced more or less continuously (except under very unfavourable conditions), and form the normal method of reproduction When * however, there is a sufficient supply of water such as is received durins the summer rains, then the chasmogamous terminal inflorescences are freely formed. In the chasmogamous spikelets examined no grains have been found, but it is very probable that they may be produced as a well-developed ovary is present. P ’ Cleistochloa Sclerachne was originally described as a species of Chionachne by F. M. Bailey from material collected by Gulliver at Lloyd Bay. The type specimen in the Brisbane Herbarium consists oi a tew small pieces of culm and some cleistogamous spikelets This material proved insufficient to give Bailey a clear idea of the species Later he transferred it to the genus Polytoca. Both Chionachne and lolytoca belong to the tribe Maydeae and are readily distinguished by their unisexual spikelets of quite a different structure. Still later Bailey referred complete plants of this species collected by Bick on ■uadu Island to Panicum marginatum var. slrictum Benth. (= Enlolasia I ric.[a Hu8^es), failing to connect them with his Chionachne Sclerachne. n lek s specimens both chasmogamous and cleistogamous spikelets are represented, the latter agreeing with those from Gulliver’s plant. e .amended description given above is mainly drawn up from Bick’s specimens. According to Bailey (Compr. Cat. Queensl. PI. 616), this species is a troublesome spear grass at Somerset, Cape York, but iere are no specimens from this locality in the Brisbane Herbarium. ‘ 1 *n Meded* Riiks Herb., Leiden, No. 67, 17 (1931), has ic entitled with Chionachne Sclerachne Bailey a specimen collected at oturts Creek in North-West Australia by Mueller. This, however, represents a new species of Chionachne. In describing certain American cleistogamous grasses, Mrs. Chase states that most of the species so far found are plants of arid regions 6 or of dry places in humid regions. This is the case with all the cleisto- gamous grasses which have been observed in Australia. A somewhat similar type of cleistogamous spikelet to that described above is pro¬ duced in the axils of the leaf -sheaths of Microlaena polynoda Hook, f . C. E. Hubbard. Addendum.

The flattened margins of the upper lemma recall the genera grouped around Digitaria Hall. Of these the only genus with which it shows affinity is Alloteropsis Presl ; this also occurs in Australia. Calyptochloa differs from Alloteropsis in having solitary racemes, a minute nerveless lower glume, a 7-nerved eciliate upper glume and a barren lower floret which is reduced to the lemma. The spikelets of the terminal inflorescence are apparently either chasmogamous or cleistogamous. Unfortunately the material is in¬ sufficient to warrant an extensive examination of several spikelets at different stages of development. In the spikelets, however, which have been dissected, the anthers vary in size from 0-5 to 1 mm * Those spikelets with shorter anthers were definitely cleistogamous as the latter were enclosed in the mature floret and entangled among the hairs of the stigmas at the apex of the caryopsis. The lower glume of the terminal spikelets is a very minute hyaline rim hidden by hairs and at first examination is easily overlooked. J The axillary cleistogamous spikelets are tightly embraced by the leaf-sheaths. Their external structure is rather different from that of the terminal spikelets. The lower glume is suppressed whilst thl upper is small but somewhat variable in size. The lower lemma is dorsally flattened or two-keeled, no doubt owing to pressure from the culm, otherwise it is somewhat similar to the lower lemma „(.* • , ?p“t, -rwet indurated and thickened downwards. The dispersal of the grain is effected by the joints of the culm disarticulating at the base of oach leaf-sheath. Mrs. Chase has noted that in species of Triplasis which have axillary cleistogamous spikelets (“ cleistogenes ”/ the culms readily disarticulate at the lower nodes.— C. E.

The only species which appears to resemble it at all closely is //. rhombocorys Schltr., an inhabitant of Nyasaland and southern Tanganyika Territory. The latter has been placed in Sect. Multipartitae ( Tacnianthera Schltr.) — erroneously, in the writer's opinion. H. longirostris and II. rhombocorys agree in general habit and type of inflorescence, in the general features of the lip and of the sepals, and in the exceptional hairiness of the petals. In II. longirostris , however, these are bilobed in the upper two-thirds, whereas in II. rhombocorys they are simple. It is significant that the petals in the latter species have the anticous margin much dilated, forming what might be considered as the beginning of an anticous lobe. In column structure the two species show many points of resemblance, the stigmas are similar, and in each the rostellum is large and truncate, and projects above the anther loculi. When first described, H. longirostris was known only from Northern Nigeria, but specimens have recently been received from Uganda and it can thus be -numbered among the many species common to East Africa and Nigeria. A large number of East African species extend as far west as the Bauchi Plateau in Northern Nigeria, especially the Savannah types such as most of the African representatives of Habenaria. A few species are also found in the Gold Coast and it is possible that H. longirostris may be one of these. — V. S. Summerhayes.

The section Plantagineae , to which this species belongs, contains a number of very striking and beautiful species of which H. mihtans Rchb. f. and //. carnea N. E. Br. are occasionally cultivated. The flowers are characterised by the usually pectinate or serrate but broad lateral lobes of the lip, while the leaves are generally radical and more or less rosulate and therefore somewhat resembling those of species of 2 Plantago. The section is distributed throughout the Indo-Malayan region and is represented in West Africa by a second species, namely, H. Engleriana Kraenzl., which possesses a spur about 15 cm. long. Up to the present, however, no Habenaria of this section has been re¬ corded from East Africa, and the two West African species are therefore isolated geographically. The Indian representatives of section Planta- gineae possess flowers of similar type, but much smaller, H. geniculata D. Don being a good example. The flowers of some of the Malayan and Indo-Chinese species, on the other hand, although as large as those of the African ones, tend to have a rather differently shaped lip with a bilobulate middle lobe. In both H. Engleriana and H. prionocraspedon the leaves, instead of being in a basal rosette or cluster, extend up the stem to immediately below the inflorescence, in which respect they approach H. geniculata , which has the leaves scattered along the lower part of the stem. — V.

This species is remarkable in the genus Vigna on account of its having the standard asymmetrical and the keel twisted through a right angle, characters which give the flower a most untidy and bizarre appearance. The style, however, is essentially that of Vigna, and not that of Phaseolus or Physostigma, genera to which this plant bears considerable super¬ ficial resemblance. The ripe fruits of Vigna nuda are unknown, but partly mature pods are similar to those of many species of Vigna. In consequence of V. nuda producing its flowers before the leaves prevalence of grass fires in the region where it grows, leaves of this species were unknown until the writer was fortunate enough to collect some dead ones still attached to the previous season’s shoots which by chance had escaped the fire. They are now described for the first time. The twisting of the keel is far from obvious in herbarium specimens, an as lerefore escaped the notice of previous authors.

Physostigma mesopo)Uicum Taub. is a plant of very great morpho¬ logical interest. The development of the peculiar spur along the fused part of the upper edge of the two keel petals at a point not far from the basal claw is dealt with by Taubert (l.c. 83). It is, however, of interest to drawr a comparison between this plant aud Vigna nuda N. E. Br., a species which, like Physostigma mesoponticumt possesses a twisted keel, and accordingly has the keel petals unequal. But V . nuda has, 3 in place of the long spur of P. mesoponticum , a much shorter outgrowth resembling a blister, situated on the surface of the inner keel petal, and not at the point of fusion of the two petals as in this species. The ovary of P. mesoponticum with the staminal tube wrapped round it frequently protrudes through the lower unfused portion of the keel. The shape and texture of the stigmatic appendage are somewhat variable as is also the size of the flowers. The variety Baumii of Harms differs from the typo only in possessing rather larger flowers. The leaves of Physostigrna mesoponticum were first described, as lobed by R. E. Fries (l.c.), but apparently, as in many species of’ the tribe Phaseoleae , the degree of lobing of the leaflets is very variable. Leaves are not represented in the Kew Herbarium. Physostigrna mesoponticum has a more northerly distribution than Vigna nuda , being found as far north as Tabora in Tanganyika Terri¬ tory, whilst it is not known to extend to Southern Rhodesia in the South. The two species have a similar life form, and are frequent on dry burnt ground at the end of the winter season. It is probable that Physostigrna mesoponticum during the wet summer season develops twining leafy shoots which scramble about among the grass with which it grows, but it is not a subshrub, as was suggested by Taubert.

Solwezi District : in dambo, after burning, at Solwezi, 20 Sept. 1930, Milne-Redhead 1162 : — Perennial herb with thick woody rootstock ; flowers white, opening in sunshine. Whilst most of the known species belonging to this genus are annuals, this plant, together with 0. tenerum Milne-Redhead, is a perennial with a woody underground rootstock well suited to thrive in the con¬ ditions offered by the open grasslands, known as dambos, which occur throughout the savannah woodland areas of Northern Rhodesia. Were it not for the annual grass fires it is possible that both these species might develop into shrubs of similar habit to 0. frutxcosum Dammer ex Milne-Redhead, which grows in the evergreen Crypto - sepalum woodlands of Angola and Northern Rhodesia, into which the grass fires never penetrate on account of the lack of a continuous ground vegetation on the loose sandy surface. On examination of a number of flowers of 0. pachybasis it was found that they were heterostylous, but inspection of the developing fruits showed that these had all come from flowers with long styles, the ovary of the short-styled flowers apparently being abortive. The species is therefore polygamous, although at first sight it does not appear so. E. Milne-Redhead.

Schonl. beside C. aquatica (Linn.) Schdnl., which it closely resembles in habit. Further investigation shows, however, that, on account of its uniovulate carpels, it must be assigned to the Helophytum group of the same section, and is nearly related to C. natans Thunb., from which it differs as indicated in the diagnosis. Some specimens of C. Wrightiana and some of C. natans are strikingly similar in general appearance, but the differential characters appear to be con¬ stant. It seems not unlikely that Schonland’s conception of C. natans included the plant figured here. There are no specimens of C. natans Thunb. from East Africa in the Kew Herbarium, and the “ distinct robust variety which Engler mistook for a variety of C. Vaillantii (Willd.) Roth ” * may have been C. Wrightiana. C. Wrightiana is a more or less amphibious plant of the high swamps and watercourses of East Africa, and the great range of variation in habit corresponds with varying amounts of water in the habitat. When growing in comparatively deep water, the internodes elongate to bring the upper portions above the surface, whilst in drier situations the internodes remain very short. The plant evidently grows in dense masses, the individual stems providing mutual support, in addition to that given by the water to the aquatic form. It is assumed that the erect, unbranched habit is normal for the plant ; the procumbent, slightly branched habit is apparently produced by the lowering of the water-level in seasonal ponds and streams, thus removing the support necessary for the weak, succulent stems. The plant is named in honour of Mr. C. H. Wright, late of the Herbarium, Kew, whose notes on his dissection of Mr. Dowson’s specimens are attached to the type sheet. — A. A. Bullock.

South Africa. Northern Zululand, near Kosi Bay, in coastal sand- dunes and bush, Aitken and Gale 63 (type) ; Col. Lugge in Natal Herb. 2 16507. Cultivated by Col. G. Molyneux at the “ Old Fort,” Durban, and in the Kirstenbosch Botanic Garden, Newlands, Cape Province. This remarkable Cycad was first recorded by Colonel Lugge at Kosi Bay, and a leaf specimen collected by him is preserved in the Natal Herbarium (16507). In 1920 R. D. Aitken and G. W. Gale made a journey to the Ingwavuma District of Zululand and collected further material, the record in their report (Bot. Survey S. Afr., Mem. 2, 18 : 1921) being “ (63) Encephalartos sp. Right on coast and in sand-dune bush, E. Ingwavuma.” In FI. Cap. v. sect. 2, Suppl. 34 (1933), the locality is recorded as “ behind sand-dune bush near Kosi Lake,” and the collectors are quoted for the statement “ stems at most a few inches high.” The description of the species given by Hutchinson is founded on the leaf specimen mentioned above and on this statement by Aitken and Gale. The existence of this species was brought to my notice by Brig.- General J. Wylie, and in 1932 Colonel G. Molyneux of Durban con¬ tributed five living specimens to the National Botanic Garden, Kirsten¬ bosch, where they have established themselves satisfactorily and pro¬ duced new leaves. One of these, with a trunk 16 inches high and a crown of 21 leaves, is figured in the accompanying plate. Two more large plants and several seedlings were received at Kirstenbosch during 1933 from General Wylie. Colonel Molyneux also gave me magnificent specimens of the male and female cones in July 1932, from which coloured drawings were made by Miss F. M. Leighton at the Bolus Herbarium. These form the basis of the present plate. Prior to the receipt of the plants now at Kirstenbosch, Colonel Molyneux had succeeded in establishing this species in cultivation in the garden of the Old Fort at Durban. The material and information received from Colonel Molyneux enable the original description to be considerably amplified. The following statements are quoted from Colonel Molyneux’ letters : — “ Encephalartos kosicnsis grows on the sea-shore on the sand-dunes and in the coastal bush within 250 yards of the sea. ... It is common in the coast sand-dunes in scattered groups for a matter of 15 miles, and a few specimens have been observed up to 10 miles inland within a few milos of the Portuguese border. . . . The coast belt of northern Zululand is unhealthy in the wet summer, and in the dry winter, prior to the introduction of motor-cars, was rather inaccessible, for there is 80 miles of sand to be got over which is soft when dry. These facts are sufficient to explain why this Cycad should have remained unknown for so long.” Aitken and Gale (l.c.) also refer to the difficulties of transport through this region, so that “ a day's journey rarely exceeds twelve miles.” “ . . . The tallest plant seen was 11 feet in height and about 3 feet 6 inches in girth. Plants from 6 to 9 feet are common. Seed brought to Durban has germinated freely. ... Its foliage is distinctive enough, something like that of E. latifrons , but the leaves are longer and do not curve : but the really interesting point is that the 3 cones are a flaming scarlet, male and female. The nearest I know to this is E. grains from British Central Africa of which the cones (in the Durban Botanic Garden) are a pale pink. . . . Apart from the red colour of its cones and its distinctly shaped pinnae, the very numerous leaves in its crown, which may even be described as crowded, and a more circinate arrangement of the young pinnae than is usual in the Cycads I know, may be worthy of remark.” The genus Encephalartos has been divided by Pilger (in Engler u. Prantl, Nat. Pflanzenfam. ed. 2, xiii. 80 : 1926) into three sections on the basis of the form of the exposed end of the female cone-scales. E. kosiensis would fall into Section B, along with the Central African species E. grains Prain, E. Hildebrand tii A. Braun et Bouche, and E. Barteri Carruthers. The information here given with regard to the stature of E. kosiensis necessitates the revision of the clavis in FI. Cap. v. sect. 2, Suppl. 28, and also modifies the conjecture made in the addendum-slip inserted therein.— R. H. Compton (Kirstenbosch). Since the receipt of Professor Compton’s description and notes Mr. Cyrus R. Barrett, of Durban, has written to the Editor as follows : “ I collected a dozen or so specimens [of E. kosiensis ] at Kosi Bay last year. I also got three seed-cones from which I obtained 250 seeds ; these I planted last November [1932] and now have just over 200 seed¬ lings, which are doing well. 1 visited the area again early this month [July 1933], and examined the plants there. It appears to me that those plants growing within three miles of the Bay and five from the sea-shore are different from those growing twenty-two miles from the shore. Those found near the Bay were growing in the open on sandy grass-veld ; the stems ranged from 12 inches to 50 inches high ; leaves up to 3 ft. long. Those grow¬ ing in bush about twenty-two miles inland have practically no stem showing above ground, the leaves are longer, running up to 5 ft., and the leaflets longer and narrower. The line of bush in which these were found runs parallel with the sea-shore, and no plants were seen farther than this from the coast, and no seed-cones were seen although a thorough search was made. In the space of a mile I counted roughly 250 plants, in some parts so close together that it was impossible to walk through the bush.” This information is particularly valuable because it confirms the sta^6men^ °f Aitken and Gale, published in the Supplement to u e *h>ra Capensis, that plants of this species have in some localities Wk** at m°8t a *eW “lc^es high.” 'V hen this species was described for the Flora Capensis I had seen only the upper half of a leaf in the Natal Herbarium, and was unfortunately not aware that living specimens had been sent to the Kirstenbosch Botanic Garden. But the leaf material was sufficient to show that the species was distinct, and the bright red cones amply confirm this view. 4 E% kosiensis differs from all others in that the middle leaflets show no definite terminal lobe, but are equally lobed all round the top. The gradual reduction of the lower leaflets to prickles is a good diagnostic feature, other South African species showing the same character being E. villosns Lem., E. Woodii Sander, and E. paucidentatus Stapf et Burtt Davy. — J. Hutchinson.

Schum. and F. crispa (Jacq.) K. Schum., to which F. cylindrica is most nearly allied, are recorded under the names F. glabra Decne. and F. capensis Endl. respectively in Dyer, FI. Cap. iv. sect. i. 779-780. The former specific epithets have priority under the International Rules. Although F . crispa has been in cultivation in the Imperial Garden at Schonbrunn near Vienna for about 150 years, the native habitat was unknown until 1906, when the late Dr. R. Marloth rediscovered it in the Prince 2 Albert Division (Kew Bull. 1909, 349). Since then it has been collected in the same area by Miss Oosthuizen, who sent a large tuber to the Albany Museum, Grahamstown, where it is now growing in the Experimental Garden. A young plant presented to Kew by the Hon. Mrs. A. D. Ryder during 1932 will probably prove to be this species. F. cylindrica is known only from the single collection recorded above.

Dyer 1251 (type). Up to the present time Fockea gracilis has been recorded only from ie sing e locality cited above, an arid sandy plain in the Great Fish er. Valjey, where the rainfall seldom exceeds 12 in. per annum and occasionally is as low as 5 in. As would be expected, the vegetation is decidedly karroid in habit, in fact the locality is at the south-eastern unit of typical Karroo vegetation. The flowering stems of F. gracilis , which twine on the small bushes 6-12 in. high, are produced annually from the underground perennial stock. 2 The species most closely allied to F. gracilis is F. sinuata (E. Mey.) Druce (= F. undulala N. E. Br.). As far as records go, the latter is known only from the Beaufort West and Prince Albert Divisions and was last collected over 100 years ago. As a rule, species of Fockea seem to be represented by comparatively few individuals. All have tuberous rootstocks, which in some cases attain a size of about 2 ft. in thickness, and as has been recorded on more than one occasion previously, Bushmen, Hottentots and other natives of Southern Africa make use of the tubers of certain species as a source of food. No doubt certain animals such as baboons seek Fockea species for the same reason. It is probable, therefore, that this is an important factor in their distribution. Early colonists soon learnt the value of Fockea tubers, and even up to the present day they are sought and uprooted for the preparation of preserve (“ confeit ”). Duplicate material of F . gracilis is in the National Herbarium, Pretoria, and the Albany Museum Herbarium, Grahamstown. R. A. Dyer.

Sept. 1911, Vie 9838. A well-marked species, clearly allied to S. rondeletioides Spruce ex Benth., but easily distinguishable by the absence of wool at the throat of the corolla and the other characters indicated in the diagnosis. The glabrous tube of the corolla is an important feature which is rare in tropical American species of the section Longi florae. It is shared by two very interesting and distinct species recently described by Dr. Ducke (Bull. Mus. Hist. Nat. Par. s&r. 2, iv. 745), from 2 the Amazons basin, which are represented in the Kew Herbarium. Of these, S. trichostyla Ducke is immediately distinguished from S. asperula by its axillary inflorescences and hairy style ; while S. ramentifera Ducke differs in its leaves and its much longer stouter corollas. A third new species of this section, S. divaricans Ducke, with terminal inflorescences, is interesting since its tube is glabrous in the lower half, and minutely papillose-tomentellous in the upper half ; this again differs widely from S. asperula in characters of the foliage and inflorescence. — N.

Mr. Davis’ material, from which the accompanying figure was drawn, is of value, not only as the rediscovery of a rare species, but also as proof that the corolla-tube may be much longer than described by Progel in the Flora Brasiliensis from the Schomburgk material at Berlin. The Kew specimens of Schomburgk 482 (= 792B) are equally short, being about \\ lines (3 mm.) long ; but De Candolle originally described the tube as 3 lines (6 mm.) long from material of the same collection at Geneva. Even, however, with such short corollas before him, Progel was quite unjustified in placing S. pedunculata in his section Rouhamon , since its corolla-tube is always longer than the lobes, and its affinity is clearly with the species of the Longijlorae which bear axillary in¬ florescences. S. pedunculata was correctly placed in the Longijlorae by Solereder in Engl. Pflanzenfam. iv. 2. 39 (1895), and this writer also indicated the very close affinity of S. trinitensis Griseb. Careful comparison of S. pedunculata and S. trinitensis fails to show any characters by which they can be kept apart as distinct species. N. Y. Sandwitii.

Malka Nidje, west of Lake Ostrovo, 1350- 1500 in., Grisebach ; Pisoderion, 12 June 1932, 1230 m., swampy spots in upland meadows in valley, very handsome deep crimson flowers, Alston and Sandwith 811. This very distinct species is endemic in the central parts of the Balkan Peninsula. It appears to be fairly widespread in Bulgaria, having been recorded from the Rila Dagh, Stara Planina, Sredna gora, Osogovo, and Plana Planina. In Serbia it is known from Vlasina, Ostrozub, and Kopaonik. In Northern Macedonia, Bornmuller found it on the Gole§nica and Dudica Planinas and on Peristeri, while KoSanin lists it from Jakupica. Alston and Sandwith’s specimens, quoted above, are from the southern limit of the species, so far as known at present. The records from Albania, Montenegro, and Hercegovina are doubtful. Grisebach, in his Spicilegium, gives the habitat and locality as “ in regione alpina Macedoniae : socialis in pratis humidis juxta rivulos m. Nidg6 alt. 4400'-4870' (substr. marmor.) (unde descendit cum aquis nonnunquam in regionem Pinus) ! FI. Jun.” In his Reise, ii. 166, the plant is listed, in a footnote, as Saponaria Asterias nov. sp. Reading pp. 163-174 of this most interesting book, it becomes clear that Grise¬ bach never crossed or climbed the Nidje (Nid2e or Nidge) Planina proper, as the name is now applied, and which rises in Mt. Kaymakchalan to 2549 m. (8284 ft.). He crossed the Malka Nidje, to the west of Lake Ostrovo, from Zejjen (Chegan) to Cruscherat (probably Krusho- grad). Grisebach’s specimen at Kew is written up “ Scardus,” but this is certainly erroneous if, as is generally held, the name Scardus should be accepted as synonymous with that of the Shar Planina. S. Asterias appears to be limited to the zones from the damp upland to the subalpine meadows, most often at between 1200 and 1700 m. altitude, though Bornmuller records it from 1000 m. on the Dudica Planina. No close relationship can be traced for the species except that with S. compacta Fisch., which has a much wider distribution than S. Asterias and is a commoner plant. The geographical ranges of the two species overlap in Bulgaria and Macedonia, but that of S . Asterias 3 is on the whole the more north-western in the Balkan Peninsula. S. compacta extends widely outside the Peninsula to Syria, Asia Minor, and the Caucasus as well as northwards to the Banat and Transsilvania, and within the Peninsula occurs generally at lower altitudes. Since the perennial habit of S. Asterias is an important (i.e. a constant) taxonomic character and is undoubtedly correlated with the habitat conditions under which the plant grows, one may postulate an ecotypical segregation of S. Asterias from the more widely spread S. compacta . W. B. Turrill.

Later material, collected by them in 1933, came from farther west in southern Albania. The 1932 material has only female flowers, whilst both the 1933 numbers consist of plants with male flowers, that is to say, the flowers have fully developed stamens but a reduced and probably non-functional gynoecium. Some of Adamovi6’s measurements do not tally with those obtained from Alston and Sandwith’s material — notably the calyx, which is given by him as “ 4-5 mm. longus, 3-5-4 mm. latus,” and the petals as “ 5-6 mm. x 2 mm.” The new specimens show a greater range in leaf shape and size, especially in maximum dimensions, than is indicated in the original description. Adamovi<5 contrasts the species with S. olyrnpica Boiss., a species from Asia Minor and not known from the Balkan Peninsula. This belongs to the same group of the Oiiles section as S. ventricosa , which appears to be at least as close morpho¬ logically to S. Roemeri Friv., a species widely spread through the central parts of the Balkan Peninsula. Typical S. Sendtneri Boiss. has entire petals (“ petalis . . . ovato-oblongis obtusis ”) but Beck (Glasnik xviii. 21 : 1906) describes a var. (vel forma) emarginata with emarginate petals from Bosnia, and similar material has been collected in northern Albania. Indeed, I suspect that S. Roemeri , S. Sendtneri , S. ventricosa , and perhaps other members of the Otites group in the Balkan Peninsula are not sharply distinguishable one from another, although most specimens can be definitely placed. It is not possible to determine the significance of this from a study of herbarium material only. With regard to Thessalian material I am inclined to regard Sintenis , Iter thessalicum 1896, No. 817b, from Mt. Zygos, as S. ventri¬ cosa Adamovid and Hausskneckt , Iter Graecum 1885, from Mt. Zygos, above Metzovo, as either the same or as intermediate between S. ventri¬ cosa and S. Roemeri. It should also be noted that Alston and Sandwith describe the calyx- teeth as “ purple.” In their dried material from all three localities the calyx-teeth and the upper parts of the calyx-tube, especially on the adaxial sides, are of a deep reddish purple. Adamovi6 in the original description of S. ventricosa says “ calyce . . . albido,” and again “ calycis fabrica toto coelo abhorret,” and Bierbach’s material in the British Museum (Natural History) herbarium agrees with these statements. — W.

Lychnis Cyrilli Richt. ex Reichb. was named (p. 55) and figured (t. cccvi. fig. 5129b) in Reichenbach’s leones in 1844 and described (in synonymy) by Rohrbach in Linnaea xxxvi. 182 (1869). It is said in these publications to grow near Tergestum (Trieste), in Sicily, near Idria, and near Belgrade. Specimens at Kew are from “ near Rome,” “ Napoli (nella valle di S. Rocco),” and Corsica. It is characterized chiefly by its slender pedicels, and Briquet (Prodr. FI. Corse, i. 565 : 1910) will not sustain it even as a variety of L. Flos-cuculi L. Degen and Dorfler were apparently the first authors to associate, wrongly, the plant here figured and described with L. Cyrilli Richt. ex Reichb. Under one or another combination the epithet Cyrilli has been used by many authors writing on the flora of the Balkan Peninsula, even since Hayek pointed out its inaccuracy in 1921. Some justification must be given for raising Hayek’s subspecies to full specific rank. In addition to the specimens quoted above, all of which are in the Herbarium at Kew, the following records may be accepted as most probably representing our plant : NidSe-Gebirge : zwischen Al§ar und dem Tribor, auf feuchten Wiesen, 800-1000 m. (25 Juni 1918 ; Scheer), and Peristeri-Gebiet : bei Dolenci, auf Wiesen haufig, 800 m. (Juni 1918 ; Gross n. 225), recorded by Bornmiiller in Engl. Bot. Jahrb. lix. 411 (1924). Albania : in pratis montanis inter Trektani et Kruma, ca 600-700 m. s.m., leg. Dorfler, recorded by Hayek in Oesterr. Bot. Zeitschr. lxx. 14 (1921). Bulgaria: Wiesen bei Knezewo, recorded by Polak in Oesterr. Bot. Zeitschr. xliii. 379 (1893) ; Kamenicki Alcek in mt. Rh. Bg. (xi. 95), recorded by Vandas, Reliq. Formanek. 58 (1909) ; and Belasitza Planina, in a damp meadow, near the village of Gabrovo, with flowers 23*7*1917, recorded by Stoyanoff in God. Sofij. Univ. xv.-xvi. 88 (1918-1920). It will be noticed that the plant is limited, so far as is known, to the Balkan Peninsula, where it occupies a fairly extensive but relatively continuous area in the central parts including Thessaly, Albania, North and South 3 Macedonia, and western Bulgaria (with the Rodopes). Lychnis Flos- cuculi L. has, of course, a much wider general distribution, but one which probably overlaps that of L. subintegm in the Balkan Peninsula. It is agreed that the morphological characters distinguishing L. sub¬ integm from L. Flos-cuculi are few, and might, indeed, be correlated with a single gene difference or at most a few gene differences. On the other hand Sandwith and Alston have informed the writer in very definite terms that L. subintegm forms an entity most distinct in the field, in southern Albania and South Macedonia, from L. Flos-cuculi, with' which they never found it associated. In addition to the charac¬ ters noted in the differential diagnosis, it seems, from dried material, that the texture of the petals may be thicker in L. subintegm than in L Flos-cuculi. Alston and Sandwith also noted that the petal laminae lie in a markedly flat plane in the living flowers. It is uncertain from available material if the short gynophore, slightly extended as a carpophore in the fruit, has any real diagnostic value. The known distribution and the field evidence suggest that a status higher than that of variety should be given to our plant. This is not the place to enter upon a discussion of the ambiguous term “ subspecies ” and it must suffice to point out that those who wish to retain L. subintegm within the species L. Flos-cuculi can use Hayek’s combination. W. B. Turrill.

Stachys serbica is a very distinct species endemic in a fairly well- marked area practically in the centre of the Balkan Peninsula. In addition to the localities given above, PodpSra records the species from a light oak-wood on dry forest soil northwards of Haskovo, in South Bulgaria. Although it is morphologically nearest to S. arvensis L. (Glecorna arvensis L.) it is certainly not a mere doubtful segregate from this. Rather it appears to be a relict type of natural open wood¬ lands whose widespread destruction by man in the Balkan Peninsula may well have reduced and restricted the area of distribution of S. serbica in an artificial manner, and may certainly be a cause of its relative rarity within the known contours of its present territory. It may be noted that while Pan£i6 records the plant “ auf Aeckern ” (label in Herb. Kew.), most other collectors whose labels or records have been traced describe the habitat as forest of oak or beech. W. B. Turrill.

Homopholis is most closely allied to Leptoloma Chase, a genus repre¬ sented in North America by L. cognaium (Schult.) Chase and in Northern Australia by L. papposum (R.Br.) Hughes. Leptoloma cognaium and Homopholis Belsonii are indeed very similar in general appearance, but the well-developed lower glume and comparatively small fertile floret of the latter readily distinguish it. The same characters and in ad¬ dition the paniculate inflorescence serve to separate Homopholis from Digitaria Hall. In both leptoloma and Ligitaria the lower glume is very small or suppressed. This species commemorates Mr. E. H. Belson, who, whilst engaged on a land-survey, rendered considerable assistance to the writer in collecting grasses in the Leichhardt District of Queensland. The name Homo¬ pholis was given in allusion to the three similar scales of the spikelet. C. E. Hubbard.

Domin, when describing Oryza australiensis y stated that his descrip¬ tion was based on specimens collected by Mueller at Sturt’s Creek. This type material is in the Kew Herbarium. It consists of four specimens, each without the base. Three of the four represent the same species and are taken as the type of 0. australiensis Domin ; the fourth specimen, however, is a wild variety of the cultivated rice (= 0. saliva L. v&r.fatua Prain). The measurements of the ligule of the latter were unfortunately included in the original description of 0. australiensis. This accounts for the length of that organ being given as 5 to 20 mm., whereas it is only 3 to 6 mm. long. The presence of two wild rices at Sturt’s and Hooker’s Creeks was noted by Mueller (Fragm. Phyt. Austral, viii. 115), who stated that there were two varieties, one with larger spikelets and stouter awns and the other with almost capillary awns and a long-cuspidate palea. These are some of the characters which distinguish 0. saliva L. var. fatua Prain from 0. australiensis Domin. The perennial habit of 0. australiensis was unknown until Mr. L. J. Brass collected an excellent series of specimens at Forest Home Station on the Gilbert River. These show a well-developed system of rhizomes. There seems no doubt that Stapf's interpretation of the structure of the spikelet of Oryza is correct, at least so far as the glumes and sterile lemmas are concerned (see Hook. f. in Trimen, FI. Ceyl. v. 182 : 1900, and A. Arber, The Gramineae, 184 : 1934). The glumes in 0. australiensis , although very small, are larger and more distinct than in any other species of Oryza. They are free from each other, the lower glume being usually slightly larger, whilst its margins at the base overlap those of the upper. The internode of the rhachilla is slightly produced above the glumes and can be readily seen between them. Roshevicz (Bull. Appl. Bot. Genet. & Pl.-Breed. xxvii. pt. 4, 125 : 1931) points out that none of the diagnostic characters seen in Oryza australiensis Domin are met with in any of the cultivated rices, and on this account he supposes that it has played no part in the formation of any varieties or groups of cultivated rice. Oryza australieims probably occurs along rivers and creeks and in swamps throughout northern Australia. In Australian literature it is usually referred to as a wild form of 0. saliva L. or placed under that 3 species. Mueller (Fragm. Phyt. Austral, viii. 1 15) records it from Sturt’s and Hooker’s Creeks ; later (l.c. xi. 130) he states that it is spontaneous and abundant in the Einasleigh and Herbert Rivers, where it was col¬ lected by Armit. Cowley (Queensl. Agric. Journ. i. 236 : 1897) writes that he has seen the native wild rice of Queensland and that enormous flocks of wild geese indigenous in Northern Queensland build their nests in places adjacent to the depressions where the rice grows, choosing the time when the grain will be ready as food for their offspring. F. M. Bailey first refers to the wild rice in a list of Queensland grasses pub¬ lished in 1877. He mentions that his only specimen is from Mr. Gulliver, Normanton. In the Queensland Flora, vi. 1844, Bailey points out that it is common in the Gulf Country swamps and that the stockholders there consider it an excellent fodder. Later (Compreh. Cat. Queensl. PI. 612) he notes that two forms of wild rice are met with in the tropical swamps of Queensland, one having dark- and the other light-coloured inflorescences. The latter is without doubt 0. auslraliensis , whilst the former may be more mature specimens of that species or specimens of 0. sativa L. var .fatua Prain. — C. E. Hubbard.

Queensland. Cook District: Thursday Island, April 1931, Hoc kings. tour species of Lepturus are now recorded from Australia. They are the following : 1. Lepturus geminatus C. E. Hubbard ; 2. L. repens 2 (Forst.) R.Br. (Northern Australia, Queensland, Polynesia, Malaya, Ceylon, Mascarene Islands and East Africa ; on sea-shores) ; 3. L. xero- philus Domin (Queensland ; Cook District) ; 4. L. cylindricus (Willd.) Trin. (Mediterranean Region ; introduced into Australia, South Africa, North America, etc.). Lepturus incurvatus (L.) Trin. (Benth. FI. Austral, vii. 668) is now referred to the genus Pholiurus. The following key is given to assist in identifying the Australian species : — Spikelets paired and opposite on each internode of the rhachis ; spikes constricted between the pairs of spikelets ; upper glume long-awned (awn 10-17 mm. long), minutely pubescent . 1. L. geminaius. Spikelets usually solitary or most of them solitary on each intemode of the rhachis ; spikes more or less cylindrical ; upper glume tapering into an awn up to 8 mm. long, or awnless, scaberulous or smooth : Perennial ; upper glume lanceolate, acuminate, usually awned : Spikelets usually 1 -flowered ; upper glume 6-14 mm. long ; lemma 4*5-5 mm. long; leaf-blades up to 20 cm. long and 4-10 mm. wide; spikes 5-15 cm. long, very stiff and rigid . . . 2. L. repens. Spikelets 2-flowered ; upper glume 4-6 mm. long ; lemmas 2*8-3 mm. long ; leaf-blades 2* 5-5 cm. long and 3*5-5 mm. wide ; spikes 5-7 cm. long, becoming flexuous . 3. L. xerophilus. Annual ; upper glume lanceolate-oblong, acute, awnless, 4-7 mm. long ; spikelets 1 -flowered . 4. L. cylindricus. The most interesting morphological feature of L. geminaius is the presence of two spikelets on each intemode of the rhachis. In the other species of Lepturus the spikelets are usually solitary, but examples with two spikelets to each intemode are occasionally seen in specimens of L. cylhidricus and L. repens. In such cases the paired spikelets usually occur in the lower or middle portion of the larger spikes, whilst in the upper part of the spike, and on smaller spikes, the spikelets are solitary. The presence of paired spikelets in these species appears to be unusual, whereas in L. geminaius it is quite nofmal. C. E. Hubbard.

Fung Province, Punter ; without precise locality, Broun (type) ; cultivated at Isleworth, Middlesex, from seed communicated by the Director of Agriculture and Forests , Khartoum (type of t. 3234, fig. 1 ) . When describing this species, Stapf suggested that it was perhaps a hybrid between Sorghum versicolor Anderss. and some cultivated Sorghum , but as S. versicolor has not been found in the Sudan, it is very probable that he intended to write Sorghum purpureo-sericeum Aschers. et Schweinf. The latter is a closely allied species which has been recorded from the Sudan, and which, according to Massey (Sudan Grasses, 16), has been collected in the same locality as Sorghum dimidi - alum Stapf (Fung Province ; Jongol’s Port). Mr. A. W. Punter, how¬ ever, who has had considerable experience with Sudanese Sorghums, informs us that S. dimidiatum does not grow in association with any other wild or cultivated Sorghum. In a note on these grasses he states that S . purpureo-sericeum is found over a wide area east of the Blue Nile up to the Abyssinian frontier, but that he has not seen it west of the Blue Nile. On the other hand, he has only found S. dimidiatum west of the Blue Nile and between the Blue and W hite Niles, where it occurs as far north as lat. 13° 30' N. in the Jebel Moya District of the Blue Nile Province and as far south as lat. 10° N« In this area it is fairly common on the open cotton-soil plains. An opportunity to grow S. dimidiatum occurred when seed of that species was communicated to Kew in October 1932 by the Department of Agriculture and Forests, Khartoum. A small quantity sown in the open in 1933 germinated readily and during the warm summer months produced plants about 3 ft. high, but only a few developed exserted panicles before being killed by cold weather. These plants had all the characters exhibited in the type-specimen and showed no signs of hybridization with any other species. This confirmed the results obtained by Punter at the Gezira Research Station in 1930, where he raised plants from seed which grew true to type. Prof. C. L. Huskins has kindly supplied the following note on the chromosome numbers of S. dimidiatum and allied species. “ Sorghum dimidiatum in common with S. versicolor and S. purpureo-sericeum has 2n = 10 chromosomes. All the species of grain sorghums so far 3 examined have 20 chromosomes, as have the grass sorghums S. vir- gaium , S. verticillijloruni , S. Vogdianum , S. lanceolatum , $. arundi- naceum and $. sudanense (see Huskins and Smith in Journ. Genetics, xxv. 241-249 : 1932, et J.c. xxviii. 387-395 : 1934), while £. lmlepense has 40 chromosomes. Longley (Journ. Agric. Res. xliv. 317-321 : 1932) reports 20 chromosomes in S. Drutnmondii and S. Hewisonii , and 40 in S. purpureo-sericeum . The origin of his material is not stated. Dr. L. J. Stadler in a recent personal communication states that young plants of Longley s 40-chromosome S. purpureo-sericeum look quite different from those of the 10-chromosome S. purpureo-sericeum obtained from Kew. The chromosomes of the 10-chromosome species are much larger than those of the 20-chromosome group and of very different shapes. Further detailed studies are necessary, but it appears highly improbable that the relationship of these two groups is a simple polyploid one, as it apparently is between the 20- and 40-chromosome grass sorghums. The 10-chromosome sorghums appear to constitute a closely inter-related group very distinct cytologically from the remainder of the genus.” It should be noted that the seeds from which Prof. Huskins raised his plants of S. dimidiatum and S. purpureo- sericeum were compared at Kew with type-material of these species and found to be correctly named. The plants of S. dimidiatum referred to in the preceding paragraph were raised from the same sample of seed. Thus there is no evidence to support the suggestion, made by Stapf, of a hybrid origin for S. dimidiatum . The differentiation of the lower glume of the sessile spikelets into a thick dark-coloured lower half and then abruptly into a thin pale upper half is most striking and gives the inflorescence a variegated appearance. The reason for this peculiar modification is not obvious. There is no doubt that it affords considerable protection to the grain during its development and also at maturity, but less than is the case with many other species of Sorghum in which the lower glume is wholly coriaceous. Sorghum dimidiatum belongs to a group of about 8 to 10 annual and perennial species, of which the area of distribution extends from Northern Transvaal to Sudan, through India to China, the Malayan Region and Australia. This group is distinguished from the remainder of the section Eu-Sorghum (sensu Stapf) by the bearded nodes, the simple branches of the panicle and the brownish spikelets. The three species hitherto examined cytologically have 10 chromosomes (see above). — C. E. Hubbard.

Rotrychium chamaeconium was originally described in 1900 from «mmjwhat poor material collected on Cameroons Mountain by Preuss. 10 HI)ecies was unrepresented in the Kew Herbarium until quite ecently, when specimens were received from Mr. A. S. Thomas, a amst in the Department of Agriculture, Uganda, who collected em on the slopes of Mount Elgon at an altitude of 6500 feet. The ganda plants are much larger than those of the type-collection, probably as the result of more favourable environmental conditions, though in other respects they are similar. 2 A member of the B. virginianum group, B. chamaeconium finds its nearest ally in the Indian B. lanuginosum Hk. et Grev., to which it bears a strong resemblance. It may be readily distinguished by the characters given in the differential diagnosis. F. K. Butters has pointed out that B. virginianum and its allies have a typical boreal distribution, the tropical members having travelled down from the north. There is no evidence, however, that such has been the case in B. chamaeconium. It seems unlikely that the species is restricted to these two localities in tropical Africa. Only in the mature fruiting condition can it be said to be at all conspicuous, while in the early stages it might readily be taken for the leaf of a young umbellifer. Its presence on other mountain masses in tropical Africa will no doubt be demonstrated in course of time. — F. Ballard.

Barlaeae Schlechter, a native of Angola. The other Tropical African representatives of Cynorchis occur in East Africa, particularly Tanga¬ nyika Territory, while the majority of the species inhabit Madagascar. It is interesting to find that a species so far from the centre of distribu¬ tion of the genus possesses such a striking combination of characters as does C. parva. These consist of the dwarf habit, the few-flowered inflorescences, the labellum with its large cuneate-flabellate central lobe and ligulate side-lobes, and the long spur. I have not yet been able to find any other Cynorchis which seems at all closely allied to C. jparva , although different species approach it in single characters. V. S. Summerhayes.

On the whole the species show a close re¬ semblance to many of those belonging to section Bilabrellae Kraenzl., but usually have somewhat larger flowers. Perhaps the most character¬ istic feature of the group is the hairiness of the inflorescence, particularly the bracts, sepals and petals, but in this as in other respects there is great variability, certain of the species being little more hairy than some members of Bilabrellae. In H. Tweedieae and its immediate allies (II. cult rata A. Rich, and H. cultrifonnis Kraenzl.) the bracts have a more or less irregularly denticulate or almost spinulose margin as well as being hairy on the surface. In II. Tweedieae these hairs (both marginal and superficial) are mostly gland-tipped, a feature which recalls many species of Cynorchis but is decidedly uncommon in Habenaria . Another important characteristic of the section is the relatively long middle lobe of the rostellum which in several species projects above the apex of the anther and is strongly developed in H. Tweedieae (fig. 4). This feature is also found in H. longirostris Sum merh ayes (t. 3211), which, however, differs considerably in other respects. So far as can be ascertained, II. Tweedieae is the first member of the Cultratae to be discovered in Kenya or Uganda, the great majority of the species being inhabitants of Abyssinia, while one or two others (perhaps rather doubtfully referable to the section) have been re¬ corded from Central Africa. From the data available it appears that II. Tweedieae occurs on most of the mountains of Uganda and Western Kenya at altitudes of about 2000 m., but more, records are required to enable us to state its detailed distribution. — V. S.

Bamenda District, Fougom, in boggy ground, UDU m., April 1931, Maitland 1509 (type). In habit and general floral structure this species is a very ordinary em Jt r genus. It is unique, on the other hand, in possessing an enormous middle lobe of the rostellum, overtopping the column, and a mg the latter appear quite insignificant. In this and some other 8pecie8 with a relatively large rostellum placed in front of and more or 2 less separated from the anther, the same evolutionary trend is seen as in the genus Bonatea where, however, the rostellum is more or less cucullate. Both Platycoryne and Bonatea are considered by some taxonomists to be merely sections of the large and polymorphic genus Iiabenaria ; each may be separated generically because the species referred to it exhibit, to varying degrees, correlated modifications in particular direc¬ tions resulting in a readily recognized assemblage of characters. In Platycoryne the species show considerable diversity in certain features, some of which are paralleled in various sections of Habenaria. There is, nevertheless, no doubt as to whether any given species should be referred to Platycoryne or Habenaria in spite of the paucity of exact differential characters. — V. S. Summerhayes.

T he section Eusatyrium of Satyrium is characterized by the possession 0 0110 or ^wo orbicular or broadly ovate radical leaves which are adpressed 2 closely to the ground rather in the manner of Plantago major L. on a lawn. These leaves are often fleshy and act as organs for water storage, being frequently exhausted by the rapid elongation of the spike before flowering and therefore either withered or partially so when the flowers are expanded. There are about a dozen species in the tropical parts of Africa and perhaps another twenty in South Africa, there is a considerable amount of variation in the size of the flowers and other characters, but on the whole the section is a fairly natural one. The species here figured is of especial interest because although it is restricted, so far as is known, to Kenya Colony, it possesses certain features in common with two species (S. membranaceum Sw. and S. princeps Bolus) which are natives of the Cape Province and are not known to occur in either Natal or the Transvaal. The chief feature is the finely fimbriate or almost lacerate margins of the petals and of the flattened apex of the lip, this being restricted to these three species. The Kenya species is a much smaller and more slender plant than its two relatives but in general respects resembles them very closely. The important differences are given in the differential diagnosis. S. fimbriatum is an inhabitant of grassland at and above 2000 m. in western Kenya Colony. It possesses rather pretty pink unscented flowers.— V. S. Summerhayes.

The presence of a pair of reduced leaves at the base of the peduncle is a peculiarity found in a large number of species ; it is doubtless of taxonomic importance, and is shown by all the species to which I have referred above. These plants resemble one another moreover in the considerable length of the peduncle of the more or less pendulous inflorescence and usually also in the colour of the flowers : these are white or greenish, except in I. rosea , where they are pink. The in¬ florescences are corymbose or paniculate, and their branchlets and pedicels are long and slender : in the new species, however, the branchlets are short, and the flowers sessile.

Brux. xi. 29 : 1928) to accommodate four South African species, three of which had been previously described by various authors under the generic names Canthium , Plectronia , Vangueria , Fadogia and P achy stigma. Robyns admitted three varieties of P. Zeyheri (Sond.) Robyns, a species occurring in Angola, Belgian Congo and Rhodesia, as well as in South Africa, and one variety of P. Chamae - dendrum (0. Kuntze) Robyns. Some of the varieties had previously held specific rank. The chief difference between Pygmaeothamnus Robyns and Canthium Lam. (= Plectronia Auctt., non Linn.) given in Dr. Robyns’ “ Con¬ spectus generum ” ( l.c . 21), is in the inflorescence : — “ Flores solitarii vel in inflorescentias simplices haud ramosas dis- positi . Pygmaeothamnus etc. “Flores in umbellas vel plenunque in inflorescentias conspicuas ramosasque dispositi . Canthium etc.” A detailed examination of the African species of Canthium (Bullock in Kew Bull. 1932, 353-389) shows that the inflorescence is even more variable than Dr. Robyns* key suggests, and it is equally so in Pygmaeothamnus , which makes the separation of the two genera very difficult. It is nevertheless convenient to retain Pygmaeothamnus as a genus distinct from Canthium , the points of difference being briefly summarized as follows : — Arbores vel frutices erecti vel scandentes ; flores 4-5-meri ; drupae plus minusve globosae, lignosae vel rarius carnosae, saepe didymae . Canthium Suffruticesnani, erecti ; flores 5-6-meri ; drupae plus minusve obovoi- deae vel globosae, valde carnosae, haud didymae . Pygmaeothamnus The most striking feature of Pygmaeothamnus is the subherbaceous habit, which at once separates it from the climbing and erect shrubs and trees included in Canthium. Herbarium specimens of Pygmaeo¬ thamnus concrescens show a striking resemblance to those of Canthium crassum Hiern, which is a tree with fire-resisting bark, widely dis¬ tributed in the grasslands and deciduous forests of Tropical Africa (Bullock, l.c. 379). In texture, shape and venation the leaves are remarkably alike in the two species, whilst the inflorescence and flowers approximate very closely. The specific name concrescens refers to the union of the peduncle and main stem which becomes more marked in the fruiting stage. A. A. Bullock.

In the flowering condition it is hard to distinguish these two species, but when in fruit they are easily separable, the legumes of C. phyllostachys being subglobose, about 4 mm. in length, and usually only 2-seeded, whilst C. annua has pods 7 mm. long, slightly less in diameter and containing up to 16 seeds. The pods of C. annua are almost identical with those of C. argyro - lobioides Baker, a species which, in the writer’s opinion, should be placed in the section Sphaerocarpae. Crotalaria annua was found growing on very hard dry ground in Brachystegia woodland, the turf of which had been removed a year or so previously. Associated with it were Crotalaria Jilicaulis Welw. ex Baker, C. Bequaertii E. G. Baker, Aster Eylesii (S.

It differs from C. bicolor , however, in possessing under¬ ground horizontal stems, from buds on which new plants develop, resulting in the production of colonies of the species by vegetative means. The plant figured was collected early in the season, when it flowers profusely. At a later date, probably during the rains, it pro¬ duces shoots considerably longer than those shown in the figure, but whether it bears flowers on these or whether they are just sterile leafy shoots is not known. The fruits develop and ripen very quickly, the plants being in fruit before the later flowers have opened. E. Milne-Redhead.

Solwezi District : by path through Brachy- stegia woodland at Mutanda Bridge, 21 June 1930, Milne-Redhead 569 : — Erect annual with trifoliolate leaves and yellow flowers in axillary clusters. Only one specimen seen. Although fruits of this species are unknown, it seems safe to place it in the section Sphaerocarpae on account of its biovulate ovary. Within this section, however, it is not easy to find an affinity for it, as, on account of the fasciculate inflorescence in the axils of the old leaves, C. streptor¬ rhyncha does not fit into any of the eight subdivisions of the section used by E. G. Baker in his account of the African species of Crotalaria (Journ. Linn. Soc. xlii. 273). Amongst African Crotalariae , C. axillaris Dryand. alone has a somewhat similar habit, but it is a member of the section Eucrotalaria , and is not nearly related to C. streptorrhyncha. A feature well shown in this Crotalaria is that the filaments of the small-anthered stamens continue to lengthen after those bearing the large anthers have reached their full length. If a bud or young flower is examined, the former set will be found to be shorter than those bearing the larger anthers, whilst in an old flower they will have grown out to nearly double their length. The small anthers are penicillate-hairy, and it is possible that they help to brush the pollen up towards the stigma and out at the end of the keel when they grow up past the dehiscing fertile anthers, which are situated considerably below the stigma within the beak of the keel. In one of the flowers examined six fertile stamens were present (fig. 6). The twisting of the beak of the keel is very noticeable in this species, a character which is not in¬ frequent in certain sections of the genus, but which is seldom mentioned in descriptions. Crotalaria streptorrhyncha is another of the numerous annuals which are endemic in the great plateau area of southern tropical Africa, the flora of which is, at the present moment, very incompletely known. In this area the distribution of many of the annual species is remark¬ ably local. In the course of covering about 300 miles on foot in the Solwezi and Mwinilunga Districts of Northern Rhodesia, the writer found this plant only once, although one would expect it, as a weed of waste places, to be of frequent occurrence.— E.

Mpika District : on poor white soil derived from quartzites and sandstones near the top of a rocky ridge, Musha Hills near Kanona on the Mpika-Broken Hill road, about 1700 m., 8 April 1932, St. Clair Thompson 1283 : — Erect herb up to 9 dm., but usually 6 dm. high ; petals yellow ; stamens and style enclosed in a spirally twisted envelope ; fairly frequent on ground incompletely colonized by herbs and grasses, growing with Anthephora acuminata Robyns, Cyperus sp. and Xyris sp. In the absence of flowers, this plant appears to be practically indis¬ tinguishable from the subsection Stipulosae of Crotalaria , section Eucrotalaria , for the legumes and seeds, although not quite mature in the available material, are remarkably similar to those of the latter genus, and their inversion might be thought to be accidental. How¬ ever, on examination of the flowers, one finds a number of very striking and taxonomically important distinctions. The keel petals are very long and narrow, and form a tube which is at first sharply bent upwards and backwards, as in Crotalaria , but is then coiled spirally into three complete turns. At the first bend of the keel there are two small out¬ wardly projecting prominences on to which the reflexed auricles of the two wing petals are hooked. The vexillary stamen is free, and ap¬ parently bears a small anther, although one was not actually seen attached to the filament in the flowers examined. The five long anthers are on short filaments, and the small anthers are on long filaments and reach to the end of the keel tube. The style follows the keel exactly, and is quite glabrous, the stigma alone being hairy. The deeply hooded standard, with a strongly reflexed claw which fits into the groove above it, has no parallel in Crotalaria. The inversion of the flowers — brought about by the bending backwards of the pedicel, so that the subtending bract appears above and behind the flower — is probably connected with the pollination mechanism. It was at first thought that this plant represented a new genus in the Genisteae , but investigation shows that it belongs to the small and little known genus Bolusia Benth., endemic in southern Africa, and hitherto placed in the Galegeae. Bolusia was based on B. capensis Benth. in Hook. Ic. PI. t. 1163 (1873). Two additional species have since been described, but it is probable that B. rhodesiana Corbishle) will have to be reduced to B. amhoensis (Schinz) Harms. Although in many respects B. resupinata strongly resembles the other species, i differs from them in having its flowers inverted. However, the P°.sse® sion of an additional bend towards the base of the keel in B. re&upma 3 results in the spiral mechanism being in the same position relatively to the ground in all the species. The inflorescence is, by reduction, one- flowered, which makes it possible for the pedicels to bend backwards. After careful consideration I feel satisfied that the most natural position for Bolusia is in the Genisteae near Crotalaria , and not, as was suggested by Bentham, next to Sylitra in the Galegeae* In the Genisteae it is exceptional in having the vexillary stamen free, but it agrees in the unifoliolate or digitately trifoliolate leaves and in the dimorphic anthers. — E.

This character was mentioned by Salisbury (Gen. 37 : 1866) in the original description C fCI1U8 antherae filamento confluentes superne foramine cuneato ut in jralmia dehiscentes.” Bentham and Hooker (Gen. Bl. in. 808 ; 1883) and Baker (Dyer, FI. Cap. vi. 444: 1897) merely statea that the dehiscence was introrse, and some difficulty was therefore experienced in assigning the present species to the right genus. Rhada- nianthus was founded on Hyacinthus convallarioides L.f., which was 2 based on specimens collected by Thunberg south of the Roggeveld in the Cape Province. The type was kindly sent on loan from the Natural History Museum, Uppsala, and it is now possible to confirm the state¬ ment that the anthers open by oblique pores about half their length. An examination of Bolus 7567 in the Kew Herbarium, cited by Baker, Z.c., under R. convallarioides , shows that the anthers open by longitudinal slits, an essential character which excludes it from the genus and suggests that it should be placed in Urgineopsis Compton. There has since been received, however, a specimen, Bolus 13210, collected “ in declivibus lapidosis in convalle flum. Hex ” which agrees in detail with Thunberg’s plant from the same region. Masson’s specimen in the British Museum (Natural History), also cited by Baker, Z.C., consists of two inflorescences : the right-hand one is definitely R. convallarioides , and was probably collected at the same time as Thunberg’s, when he and Masson were travelling together. The left- hand specimen on Masson’s sheet looks somewhat different but the material is insufficient for determination. Rhadamanthus urantherus is distinguished from R. convallarioides by the anther thecae being shortly tailed at the base. In the type specimen the length of the tails is not constant and in some flowers is very short, but in no case are the tails entirely absent. The species was introduced to the Royal Botanic Gardens, Kew, in a consignment of bulbs forwarded from South Africa by Miss Winsome Barker during 1932. The bulbs flowered in March of the following year in the leafless condition, a feature common to certain species of the closely allied genus Urginea. Two to eight filiform leaves were produced from each bulb during November 1933, and it is noteworthy that whereas the peduncles are very minutely puberulous, the leaves are glabrous. The allied genus Urgineopsis was founded on the single species U. Salieri from the Cape Peninsula (Journ. Bot. 1930, 107) and “ differs from Urginea chiefly in the markedly gamophyllous perianth ” and “ from Rhadamanthus in the erect flowers and non-connivent stamens.” Prior to the publication of this, Miss A. Duthie in Ann. Univ. Stellen¬ bosch, vi. sect. A, no. 2 (Feb. 1928), gave an account of the species of Urginea of the Stellenbosch Flats. In this paper Miss Duthie described five new species, three of them, U. pygmaea , U. minor and U. gracilis , with perianth-lobes united at the base. At the same time she drew attention to the fact that U. Dregei Baker (1897) also had the perianth-lobes united at the base, and proposed a section Pseudo- urginea for the four species distinguished by this character. R. A. Dyer.

All these collections were described as a vine. The species of the scandent genus Nissolia are somewhat difficult to separate owing to evident variability in certain characters such as the size of the leaflets, the presence or absence of scattered bristles on the brunchlets, calyx and fruit, and the development of the axillary inflorescence. The present species is clearly well marked by its com¬ bination of the following features : completely non-pubescent branch- lets, leaves and inflorescence ; copious setcse development on the branchlets, and particularly on the inflorescence and the margins of the conspicuous bracts ; remarkably well-developed and elongate racemes and panicles ; large flowers with setose, but otherwise glabrous calyx and long calyx-teeth ; and large sparsely setose fruit. The fact that Mr. G. B. Hinton has made as many as six collections of a vine presenting these peculiar characteristics is a fair guarantee of its specific status even in a genus whose members have frequently been regarded as ill-defined.— N.

The remaining species assigned to the genus Platymisdum are glabrous in these parts with the exception of the South Brazilian P. pubescens Micheli, the Bolivian P.fragrans Rusby, and the Bolivian P. ellipticum Rusby. Of these the first two are easily distinguished from P. lasio- carpum by the characters given in the diagnostic description ; no material of P. pubescens has been seen, and only fragmentary foliage of P. fragrans. The third, P. ellipticum , which has fulvous-sericeous fruits, has alternate leaves, small alternate leaflets, and a pod with the upper suture slightly winged, characters which obviously remove it from the genus Platymisdum . — N.

Goyaz, Aug. 1912, Ph. von Lutzelburg 1223, 15483 ; West Bahia : campinas Boa Esperan9a, 1912, Ph. von Lutzelburg 15484. The present plant was first described by H. Pfeiffer in 1925 under the name Syntrinema brasiliense Radik, et Pfeiff. This name had actually been suggested by Radlkofer ten years previously, as is shown by a note written on a sheet of von Lutzelburg 1223 in the herbarium at Munich. The preparation of the description and accompanying notes, 2 however, was the work of the junior author, Radlkofer being 95 years of age at tho time it was written. The description is accompanied firstly by a habit figure (fig. a) of the plant originally seen by Radlkofer. Secondly, there are six figures (figs, c-h) purporting to be dissections of the spikelet of Syntrinema , but which, quite obviously, belong to a very different plant. Lastly, a ground plan of the spikelet (fig. b) is given which also does not refer to Syntrinema. In fact, the last two sets of drawings illustrate the genus Chorisandra — a genus only very distantly related to the present one. They appear to be adaptations from N. E. Brown’s drawings of that genus in C. B. Clarke’s “ Illustrations of Cyperaceae ” (t. 119). The description itself is also a mixture combining the gross mor¬ phological features of Radlkofer’s Syntrinema with the floral details of one or more species of Chorisandra . Curiously enough, the particular character which served Radlkofer as a basis for his generic name is entirely ignored. In 1915 Radlkofer wrote as follows on a sheet at Munich : “ Genus Cyperacearum novum, ut videtur, cujus stamina in flor. connata nomen Syntrinema (S. brasiliense) supped itant.” One is forced to conclude that the published description was partly based on figures illustrating dissections of Chorisandra , which had in some way become associated with the specimens of Syntrinema. Pfeiffer must have had some misgivings, however, regarding Radlkofer’s note about the connate stamens, since, in his remarks following the description, he mentions that neighbouring male flowers have their stamens connate at the base. This interpretation, although quite incorrect, was the only way of reconciling Radlkofer’s observa¬ tion with the assumption that the male flowers were monandrous as in Chorisandra. The expression in the specific description, “ ovarium 2-lobum, 2- loculare (an semper ?),” calls for explanation. It probably arose from the fact that in N. E. Brown's drawing of the ground plan of the Chorisandra spikelet two small round objects are shown within tho ovary wall. To the uninitiated these might seem to indicate the presence of two loculi or two ovules, whereas in reality they represent the number of styles. It should be mentioned that in 1933 Dr. Pfeiffer placed a note on the sheet of von Lutzelburg 1223 in the Munich herbarium to the effect that the original description required emending. Since then he has written saying that it had been his intention to publish another paper and a rectified description, but that he would refrain from doing so in view of the present investigation. The stamens in Rhynchospora confusa arc interesting. In the early stages of the male flower, and possibly also in the hermaphrodite flower, the filaments cohere, to what extent it is difficult to judge from dried material. In this condition the stamens reach maturity. A definite articulation is present between filament and anther, while the anther itself is peculiar in possessing a short sterile portion above this articulation. When the anther is quite mature and conditions 3 favour dehiscence, the filament apparently lengthens suddenly, possibly by rapid elongation of individual cells, the anther emerges from the squamae and dehiscence takes place. After this, the anther disarticu¬ lates from the filament and drops away. Exactly the same arrangement is seen in Rhynchospora hirta Boeck. (R. monadelpha C. B. Clarke), and a good figure showing the connate stamens was published by Lindman in Bih. Svenska Vet.-Akad. Handl. xxvi. Afd. 3, No. 9, t. 5 (1900). The disarticulating type of stamen is found also in R. globosa Britton and R. minarum C. B. Clarke, although connate filaments were not observed. Nees also draws attention to this type in Nov. Act. Nat. Cur. xix. Suppl. 1, 99 (1843), where, in a description of Sphaeroschoenus Wallichii (Rhynchospora Wallichiana Kunth), he says, “ antherae basi veluti in stipitem sterilem filiformem attenuatae eiusque opera filamento, strictura arguta intercedente, impositae, ita ut primo attactu defluant.” All the specimens seen of Rhynchospora coyifusa had obviously been badly burned, so that our illustration may not be altogether typical. Uninjured plants probably attain much larger dimensions, the inflores¬ cences, without doubt, being borne on considerably longer culms. F. Ballard.

A somewhat straggling and lolling plant of the temperate rain forest.” Originally collected by Griffith nearly a century ago, A. linearifolia was described from Griffith’s sterile specimens by C. B. Clarke in the Flora of British India and relegated to the species non satis notae. Capt. Kingdon Ward’s excellent material now enables A. linearifolia to be assigned its proper place in the genus. From A. nutans Dunn it is readily distinguished by the glabrous peduncle, by the conspicuous cupular apical expansion of the pedicels, and by the calyx segments being connate halfway or more. From A. angustifolia (Knagg) Airy- Shaw, which agrees with the present plant in the points just mentioned, A. linearifolia differs in its thickened, almost fleshy peduncle and pedicels, and in its short, subconical corolla. The occasional occurrence of flowers in which the filaments are connate into a tube (fig. 8) affords an interesting parallel to some American genera of Thihaudieae , such as Satyria Klotzsch, in which united filaments are a constant feature. — H.

Corolla not transversely 2 Vernacular name (Assam) : “ Horu Gumani.” The present species was recognized as new, and the accompanying plate and description were prepared for publication, several months before the first number of Assam Forest Records , in which A. Kanjilali appeared, was received at Kew (Dec. 1934). It is thought advisable to publish them, since the original description of the species is somewhat brief, and certain floral details on the plate are not quite accurate. Instances of the latter are the curiously Fuchsia- like corolla, stated to be “ more or less diagrammatic ” but quite unlike anything in Agapetes with which the present writer is acquainted ; the anther- thecae apparently dehiscing by slits and represented as quite distinct from their beaks, which have the appearance of a prolongation of the connective ; the spurs, in one case, arising from the front instead of from the back of the beaks ; and the barrel-shaped rather than subdiscoid stigma. As the specimen figured in Assam Forest Records is part of the same collection ( Kanjilal 4090) as that from which our plate was drawn, it seems probable that the artist, in attempting to give the dissections a life-like appearance, drew rather more freely upon his imagination than the condition of the dried material warranted. His habit-figure, on the other hand, gives a good idea of the plant. Das gives A. buxifolia Nutt, as the nearest ally of A. Kanjilali , but, beyond the fact that both species are referable to the Series Longifiles , there is no very close affinity between them. In foliage, A. Kanjilali is similar to A. Hosseana Diels, but the much larger flowers, densely tomentellous calyx-tube (receptacle) and unusually elongate glabrous filaments readily distinguish it from that species and its immediate allies. — H.

Without precise locality, Sieber 89 (Herb. Mus. Brit.). In the field, E. caespitosus may be distinguished from E. ovatus by its compact tufts with more erect and usually taller culms. It shows a considerable range of fluctuation apart from the marked variety described below. In some cases the differences are no doubt due to the varied conditions of soil and moisture under which the species is found. These would account for the range in the size of the inflorescence, plants with greater vigour having elongated and often interrupted panicles. Such variations occur here and there throughout the area of the species and have probably no systematic value. Several of the specimens cited above from Southern Queensland and Northern New South Wales, however, differ from the typical form in often having smooth peduncles and leaf-sheaths, and shortly bisetose lemmas ; they may represent a second distinct variety.

E. ovatus var. pubiglumis C. E. Hubbard ; varietas nova, a typo recedens glumis brevissime pubescentibus, spiculae rhachilla breviore glabra, ovario glabro, panicula densissima. Western Australia. Without precise locality, Drummond 312 (type), 348. This variety resembles E. ovatus in habit, the latter also occurring in Western Australia. The structure of the spikelets is, however, nearer to that of the Queensland and New South Wales species, E. caespito8U8. Although Echinopogon ovatus is the most widely spread of all the species of this genus, it is very uniform both in habit and structure. In Queensland it is frequently found in moister situations than any of the other species, and this is probably the case in parts of Ne'V South Wales ; in New Zealand, on the other hand, it grows in dry places (according to Cheeseman). Echinopogon Sieberi Steud. was based on “ E. ovatus Sieber Hrbr. N. Holl.” A specimen in the Kew Herbarium labelled “ Sieber 89 which is referable to E. ovatus , may possibly be part of the type' collection. The corresponding specimen in the British Museum Herbarium is, however, E. caespitosus . Steudel’s description agree best with E. ovatus , e.g. the flaccid leaves 1-2 in. long, the 4 lin. l°nk 9 panicle, and the bearded apex of the grain. On this account E. Sieberi is treated as a synonym of E. ovatus. The types of Gandoger’s species, E. virens , E. purpurascens and E. novae-zelandiae , which are in the Botanical Institute Herbarium, Lyon, have been kindly lent for examination by Dr. J. Beauverie. They represent the same species as E. ovatus ; in fact the type of E. novae-zelandiae is a very good match with a syntype of Agrostis ovata G. Forst. in the Kew Herbarium, whilst the other two only differ in having smaller panicles. Gandoger cites Maiden as the collector of E. virens , but there is little doubt that the real collector was E. Betche (who collected E. ovatus at Walcha in Dec. 1898), and that the specimen was only communicated by Maiden to Gandoger. A duplicate of Betche’s plant in the Kew Herbarium exactly matches the type of E. virens. The majority of the specimens used by Bentham in the preparation of the account of Echinopogon ovatus for the Flora Australiensis (vii. 599) were correctly named, but one (Liverpool Plains, Moore 112) is now placed with E. intermedius , and a few others are cited under E. caespitosus. In the Agricultural Gazette of N.S. Wales, vol. iii. p. 388, Turner gives an account, together with a plate (t. 28), of E. ovatus. The latter illustrates two species, the drawing on the left- hand side and figs. D, B and C (left) being of E. intermedius , whilst that on the right and figs. A, B and C (right) are of E. caespitosus. 6. E. McKiei C. E. Hubbard ; species nova, affinis E. ovato (G. Forst.)

Muell. in the Flora Austral iensis, stated that the aspect of the species was nearly that of the Asiatic genus Apocopis . It is in fact more closely allied to Apocopis than to the genus Ischaemum in which it was first placed. This was partly recognized by Hackel, who transferred it to Lophopogon , a genus which he had segregated from Apocopis ( sensu Benth . ) . Actually Sclerandrium seems to occupy an intermediate position between Lophopogon and Apocopis. Lophopogon Hack, is here restricted to L. tridentatus (Roxb.) Hack., the type species, L. Kingii Hook, f., and a third undescribed Indian species. Two species originally described under Lophopogon , namely, L. intermedius A. Camus and L. tenax Balansa, are referable to Sclerandrium : the former is transferred above as a specimen of the type-collection has been examined, but the latter has not been seen, and it is only from the description that it is recog- nizcd as belonging to this genus An undescribed species of Sclerandrium !#ET ^T£(IrmS!“" by specim'“ coll“*'d “ «*■» he proposed to ell SderandriZ Z sometime d h, 1,®'““ wl“'h oil the Kew material ol that large and difficult th “ si "m‘"g included A„u, $£) SedtlemtnT18 ^ “ the ««»>tribe IscfuimiZ, Stapf genera together withT/'^ 7 th° S?btnbe Saccharin*.

Hackel in his monograph of the Andropogoneae (DC. Monogr. Phan, vi. 250 : 1889) proposed a new subgenus Digastrium for Ischaemum fragile R. Br. It was characterized by solitary racemes, obovate- ventricose joints and pedicels, awned perfect sessile spikelets, and barren pedicelled spikelets reduced to the two glumes. He stated further that Ischaemum subgen. Digastrium approached Rottboellia no doubt on account of the general resemblance shown in the much- thickened joints and pedicels. More recently A. Camus (in Bull Mus H.st Nat. Pans, xxvn. 372: 1921, in obs.) has raised the subgenus Digastnum to generic rank. Later the same author (in Bull Soc and | ra',ce’ !xx' 849 : ,192+) gave a generic description of Digastrium Forsk'1 1 Vlnf IS°rSed affimtir with Ischae”™m L. and' Sekima bablv1’ °n the gJenera °f the subtribe Ischaemirm (probably before 1917), also removed the subgenus Digastrium from '^emum but he did not publish it as a distinct genus.

The diagnostic characters used a sulw^1 ac 0 an<^ ^amus f°r distinguishing Digastrium (either as solitarv US °r genus) fr?m Ischaemum are with one exception (the y racemes) found in several undoubted species of Ischaemum. 4 4 For example, in I. rugosum Salisb. the joints and pedicels are somewhat similar in general structure to those of I. fragile R. Br., whilst the pedicelled spikelets are frequently much reduced and barren. In /. fragile R. Br., however, the pedicelled spikelets are somewhat variable ; in some spikelets the lower floret is represented by the lemma and palea, and a rudiment of the upper floret may also be found, while in other spikelets both florets may be suppressed. Hackel apparently had only spikelets of the latter type for examination. The solitary raceme is thus the only distinguishing feature left between Digastrium and Ischaemum. It is here that a consideration of Ischaemum Baileyi becomes important. This species belongs to the same group as I. fragile and would have to be placed in Digastrium if that were retained as a distinct genus. The racemes are mostly paired as is commonly the case in the genus Ischaemum , but solitary racemes are occasionally met with which serve to connect it with I. fragile . Thus all the diagnostic characters given for separating Ischaemuffl and Digastrium break down. In his account of Ischaemum fragile , Hackel reverses the description of the lemma and palea of the lower floret. This may have been due to having insufficient material for examination, or on the other hand, in the course of dissecting, the various parts may have become detached as is frequently the case. The peculiar palea might then be easily confused with the lemma. This palea is usually thinly coriaceous and has thin hyaline margins which fold over the male flower, whilst the lemma is thinner and narrower. F. M. Bailey (ll.ee.) gives Port Denison as a locality for Ischaem vftf fragile R. Br., but no specimens from this area were found in th« Brisbane Herbarium. Some fragments collected by A. Mitchell i# Sept. 1895, on “ Frasers Islands/’ probably belong here. The raceme8 are solitary, but still partially enclosed in the uppermost leaf-sheaths* If the label is correct and the locality is the same as Fraser Island (Great Sandy Island), then this material considerably extends the known distribution of /. fragile. Ischaemum Baileyi and /. frag ifa as far as is known at present, are geographically separated, the form®* occurring only in the extreme north of Cook District and on the adjacent islands, whilst the latter ranges southwards from the Endeavour River. The specimens of 7. Baileyi collected by Bick (no. 54) oil Mabuiag Island were incorrectly referred to Polytoca cyathopoda W F. M. Bailey (Qucensl. Agric. Journ. xxvii. 69 : 1911). — C. E.

The genus Zoisia is represented by about six to eight species which are found, mainly along the coasts, in Mauritius, South India and Ceylon, Japan. China, Malayan Region, Solomon Islands, Eastern Australia and New Zealand. In the last-named country, however, the species ascend to comparatively high altitudes inland. The Australasia11 species, in common with other members of the genus, have usually been included under Zoisia Matrella (L.) Merrill (Z. pungens Willd.). The area of distribution of the latter extends from Mauritius to the Soloin°n Islands. It differs from the Australian species Z. macrantha Desv- by its narrower leaves, more slender racemes and smaller spikelets (2* 3*5 mm. long), and from the New Zealand species by its denser racemes, with more numerous and smaller spikelets ; whilst Z. macrantha Des^j may be distinguished from the New Zealand species by its taller an stouter culms, more rigid and wider leaf-blades, stouter and den 3 spikes and more numerous obliquely ovate-oblong or lanceolate-oblong spikelets. The Australian species seems to be more closely allied to sinica Hance of China than to the New Zealand species. Desveaux’s species Z. macrantha has been somewhat neglected, no doubt owing to the rarity of his “ Opuscula.” Bentham did not include it in the Flora Australiensis, whilst C. Mueller redescribed it as a new species, Z. Brownii . Z. iodostachys Gandoger is represented in the New Herbarium by a duplicate from the United States National Herbarium communicated by Gandoger. This contains a mixture of macrantha Desv. and Z. Matrella Merrill, but Gandoger’s description applies only to the former. Zoisia macrantha Desv. is of frequent occurrence on the coasts of Southern Queensland. It often covers large areas on the sand dunes above high-water mark, where it forms pure masses or grows in associa¬ tion with Sporobolus virginicus (L.) Kunth, Spinifex hirsutus Labill., Cynodon Dactylon (L ) Pen., etc. In some places Zoisia macrantha grows on sand dunes bordering salt marshes, and it is possible that it might occur in the salt marshes themselves, but such a habitat would be unusual, at least in Queensland. In N.S. Wales, however it is recorded from salt marshes. So far it has not been recorded further north than Emu Park near Rockhampton, Central Queensland, its place being taken in Northern Queensland by Thuarea involuta (Forst.) R. & S., etc. The southernmost locality from which specimens have been examined is the sandy coast of East Gippsland in Victoria. Bentham (FI. Austral, vii. 506) and Rodway (Tasman. FI. 258) record a Zoisia from islands in the Bass Strait, whilst J. M. Black (FI. S. Austral. 665) states that Z. pungens forms a dense sward near the Rocky River Kangaroo Island, South Australia. It is probable that both records are referable to Z. macrantha Desv. “ PrTckfv rounTn" *" ?,0mTmonl>: known as “ Coast Couch Grass ” or o car l i * a ^ m[ass' lt 18 of conslderable economic importance as a sand-binder.

This very beautiful Blepharis stands out from among the other species of Section Eublepharis, to which it belongs, on account of its robust habit, its large flowers and its conspicuously nerved papery bracts. B. Homblei De Wild, has flowers nearly as large but is very different in other respects. Of the species given in the Flora of Tropical Africa, B. Ilornbyae comes nearest to B. integrifolia (L.f*) E. Mey. (B. molluginijolia Pers.), which agrees in the possession of bracteoles and in the trailing habit, but is a very much smaller weedy plant with insignificant flowTers. The species is named after Mrs. H. E. Hornby, who, together with her husband, has contributed so many specimens from the district around Mpwapwa, Tanganyika Territory, an area which appears to be very rich in endemics. B. Ilornbyae grows on sandy soil in the evergreen thickets which fringe the seasonal streams, and uses the evergreen shrubs for its support much in the same way as Lonicera Periclyrmnum L. does in Europe. — E.

It is not without hesitation that I place this species in Anisotes , a genus which up to the present contains only plants with small and inconspicuous bracts and bracteoles. However, the striking similarity of the corollas to those of the other species of Anisotes suggests that this is its true position. The West African A. Zenkeri (Lindau) C. B. Clarke has many-flowered axillary inflorescences, but they are very shortly pedicelled and are not strobilate. In appearance A. umbrosus is remarkably similar to Adhatoda Engleriana (Lindau) C. B. Clarke, but the petiolate leaves without auricles and the longer and more slender flowers readily distinguish the former species. The pollen of A. umbrosus is “ knotchenpollen ” with two stoppels, as in both these genera. — E. Milne-Redhead.

The first-named 2 differs in the shape of the petals, which are much widened at the apex on the outside. I can see only very slight differences between D. Johnstoni and D. Stolzii , but in view of the small amount of material available of the latter it seems best to maintain it as distinct for the present. With regard to D. Reichenbachiana the flowers on the specimens of Welwitsch 694 (the type-collection), both at Kew and at the British Museum, are so poorly preserved that it is difficult to be sure of their exact structure. So far as they can be distinguished, however, they seem to differ from those of D. Johnstoni , especially in the lip. There are specimens at Kew from Kenya Colony and Uganda which are very similar to Welwitsch 694, and in these%the lip, while agreeing with Reichenbach’s description of the Angolan species, is quite distinct in structure from that of D. Johnstoni. An interesting feature in all the species here figured is the presence of staminodes, which, so far as I can ascertain, have not been recorded in this genus, and are not shown in any of the illustrations I have seen. They appear to have been interpreted as stigmas by some students of the genus, but at all events in the groups of species here concerned the stigmas and staminodes are quite readily distinguishable from one another, firstly on account of the structure and secondly from the positions occupied. In other groups within Disperis the stigmas and staminodes seem to approach one another in structure and in position, and in particular cases it is difficult from dried material only to be certain of the nature of any given organ. In each species so f&r examined belonging to the groups here illustrated the staminodes are placed at the base of the column, one on each side. In D. cardiopeta to Summerhayes (tab. 3270) they are very poorly developed, being represented merely by a transverse papillose band, but in the otb®* species they are quite easily visible on dissection. — V.

Johnstoni Rchb. f. From the latter it is readily distinguished by the much dilated lower portion of the petals, as a result of which the galea composed of the joined dorsal sepal and petals is cordate at the base instead of cuneate as in D. Johnstoni (see tab. 3269). D. togoensis Schltr. is a very slender plant with extremely small leaves and bracts, these, on the other hand, being well developed in D. cardiopetala. It will be seen from the drawings of the lip in D. Johnstoni and this species that the so-called “ appendages ” of the lip are in these cases (and also probably in D. katangensis Summerhayes, tab. 3271) formed by the broadening or splitting of the lip claw, which is then sharply reflexed, the inner or lower surfaces on each side of the bend being adnate to one another for a varying distance in the different species. It is doubtful if there is any real outgrowth from the upper surface of the claw, although such development may have started in D. katangensis. — V. S. Summerhayes.

There are five other species in this minor group* two, D. Kerstenii Rchb. f. and D. leuconeura Schltr., being natives of Tanganyika Territory ; two more, D. virginalis Schltr. and D. Nelson t* Rolfe, occurring in the Transvaal ; while the fifth, D. oppositifolM Lindl., is widely distributed in the Mascarene Islands. I) . dicer ochdn, in spite of being the northernmost representative of the group, resembleS most closely the two South African members, both of which have the two appendages of the lip longer and each provided with a distinct claw below the point of divergence into lobules. In D. Kerstenii tin9 elongation is much more pronounced, the claws of the appendage® being as long as the claw of the lip proper, and many times longer than the reflexed apex of the lip. In D. leucofbeura and D. oppositifd & the structure of the lip is quite different in plan from that in th€ other species. Superficially, however, all the species bear a very close resemblance to one another, at any rate so far as drieu specimens are concerned, and only careful examination of the flowed reveals the technical differences. It is remarkable that D. dicerochila is so widely separated geograpb1' cally from its nearest relatives, but it is probable that other species Disperis remain to be discovered in Africa. Like all the other norths11 members of the genus the new species occurs in mountain regions llt high altitudes. The specimens in the two Kenya Colony gatheriugs are more robust and have larger flowers than those from Ruwenz0*1' but the floral structure is apparently identical.

Its affinity is with G. rejlexum L., which occurs in the same area but has a wider distribution, being found also in Central Italy. In foliage and in the general characters of the aerial parts there is a definite resemblance to G. bohemicum L., a species with a wide distribution in Central and in certain parts of South Europe, and which also occurs fairly widely in the Balkan Peninsula. G. bohemicum is, however, an annual, or at most a biennial, while G. anstatum is a perennial. The material collected by Alston and Sandwith on their two expedi¬ tions is in the flowering condition only. Certain differences between Tif Macedonian and the Albanian plants call for comment. Ihe Macedonian specimens have a denser indumentum, especially on the lower parts of the stems and the petioles, and somewhat larger leaves than the Albanian. The leaf segments are also somewhat broader or are more nearly contiguous or even slightly overlapping in the former, while they diverge, often considerably, in the latter. Bornmuller (l.c.) has pointed out certain inaccurate statements in the original description. Observations on the new specimens confirm Bornmuller’s remarks. -W. B.

Beauverd (l.c.) retains the name Cicerbita Wallroth (pro max. parte) for a genus which, in his sense, includes Mulgedium Cass., Lactucopsis Schultz Bip., Mycelis Cass., Cephalorrhynchus Boiss., and Steptorhamphus Bunge as sections or subgenera, but is distinguished from Sonchus and Lactuca by the structure of the pappus. Generic limitations, at least in such a family as the Compositae, are bound to be governed very largely by subjective bias and scientific convenience. It is obviously advantageous to separate from Lactuca those plants having so distinctive a type of pappus as that found in Cicerbita sensu lato. Whether they should be all retained in one genus or distributed amongst five or fewer is a matter of secondary importance. Here the original name for the plant figured is retained, since it appears to be of no advantage to sink the genus to the rank of a subgenus without change of content, and still less to place it in the genus Mycelis. The problems connected with the species itself are much more interesting. It was first described by Boissier from material collected by himself in Lydia, western Asia Minor : “ in Sipylo supra Magnesiam ubi fructiferum Julio 1842.” In the Flora Orientalis (iii. 820 : 1875), specimens collected by Balansa in the same locality and at Yachamichlar Kioi, Phrygia, are placed with the type. Haussknecht (l.c.) recorded it from ‘ eollibus dumosis supra Kalabaka pr. mon. Meteora.” Jhis Ihessalian material was collected by Haussknecht in the summer o 1885. He notes that the species was collected by Borbas on the lower Danube at the Iron Gate. Javorka (l.c.) adds the synonyni C. hispidus auct., var. cataractarum Simk.” Bornmiiller (l.c.) records the species from North (Serbian) Macedonia, “ Demir-kapu : Felsige, waldige Abhange der Bergriicken rechts vom Vardar ” and also notes 3 that he collected it on the Logman near Amasia in 1889. The evidence so far available thus indicates Cephalorrhynchus glandulosus to be one of the numerous plants common to Asia Minor and the Balkan Peninsula, but one which has a strongly discontinuous distribution on both sides of the Aegean Sea. It is no doubt one of those species which attained distribution in Europe and Asia when the Aegean continent gave a continuous land connection, and its occurrence as far north as south¬ western Roumania, as far west as Albania, and as far east as Amasia, combined with the apparent wide discontinuity of its stations, suggest it is of Tertiary and not of recent origin. Alston and Sandwith describe the floret colour as white, or more accurately as a dingy or creamy- white . Beauverd says that Bornmiiller gives the floret colour as “ ligules violettes ” on a label of his material of No. 5237, iter Anatol. III. 1899. When the plant is dried and the florets of the capitula are connivent, a more or less violet colour is Boissier does not describe the florets. Hayek (l.c.) says nores lutei.” Ihe structure of the pappus is distinctive. The cypsela tapers into a beak which is green and not dark-brown as is the main part of the fruit. The beak at its apex enlarges to form a pyriform hemispherical swelling which is flat at the top. The disk portion of this swelling easily becomes detached from the ripe fruit.

Albania. Ostrovice Range, 1700-1850 m., upper slopes, on stony ground, and in open beech woods, 4 July 1933, Alston and Sandwith 2072 : — “ Plant erect ; flower a curious pale, dingy pinkish-mauve ; stamens cxscrted.” N. Macedonia. Inter Gostivar et alpes Korab in montibus Scardicis australibus supra Mavrova in fagetis umbrosis subalpinis, altitudine 1350 m., 2 Jun. 1918, Bornmuller (type). The genus Solenanthus contains about 18 known species. It has a wide Eurasiatic distribution and extends also into North Africa. S. Reverchonii Degen is confined to southern Spain. S. petiolaris DC. is recorded from as far east as Afghanistan and also, as are other species, from Central Asia. Six species are known from Europe, in addition to the one described above, and of these four occur in the Balkan Peninsula. The nearest genus is Cynoglossum , from which Solenanthus differs chiefly in the exserted stamens. Several species now included in the latter, including S. apenninus (L.) Hohenack., the longest known species, have at one time or another been placed in Cynoglossum. The above description has been prepared from the material at Kew of Alston and Sandwith 2072. We are greatly indebted to Prof. Bornmuller for the loan of type material. This has enabled a com¬ parison to be made between two of the original sheets and the abundant Albanian specimens. The material sent by Prof. Bornmuller as “ Typus herb. Bomm.” consists of “ nur der untere und oberste Teil.” Obviously the plant it represents was a very robust specimen. No extreme base (rootstock) is present. Prof. Bornmuller definitely describes the plant as “ biennis.” It is not possible to check this on the material received on loan from him. Nor is it possible to check the description of the habit as having floriferous branches right to the base and “ ergo thyrsum uni cum maximum latum formante.” This, if correct, is probably a peculiarity of the extremely robust individual plant, at least it is not found in Alston and S&ndwith’s specimens. Hayek (Prodr. FI. Penins. Balcan. ii. 52 : 1928) keys the species on the character “ caulis a basi pyramidatum ramosus ramis omnibus floriferis ” as contrasted with “ caulis a medio circiter ramosus.” This is unfortunate since the new Albanian material comes into the second category. The original description requires a number of modifications. The shape and position of the coronal lobes (“ fornices ”) as given by Bornmuller do not agree with that found in the original material. In both the Macedonian and the Albanian plants the coronal lobes arise 3 just at or less than 0*5 ram. above the middle of the corolla-tube, and their shape is certainly not ovate narrowly oblong-triangular or oblong linear and clavately thickened in the upper part. This matter is of some importance since Brand (Pflanzenreich IV. 252. 153 : 1921) uses as a primary character in his key the position of the coronal lobes. For S. Biebersteinii , Brand (l.c. 159) describes the position of the coronal lobes as “ ad fauccm affixi.” There is a certain amount of fluctuation in the size of the anthers in S. scardicus , but when moistened they are decidedly longer than (up to three times as long as) 0-5 mm., which is the length given by Bornmuller. S. Biebersteinii DC. (Prodr. X. 165 : 1846), a species of the Crimea and Caucasus, with which S. scardicus is compared, differs specifically in the short corolla and the less robust habit. S. Reverchonii Degen from S. Spain, which with S. Biebersteinii and S. scardicus shows the filaments long-adnate to the upper half of the corolla-tube, is of very distinctive habit. The other species of Solemnthus from the Balkan Peninsula appear to be quite distinct from S. scardicus. S. albanicus Deg. et Bald. (Magy. Bot. Lap. ii. 315 : 1903), originally described (Nuov. Giorn. Bot. Ital. vi. 337 : 1899) as a species of Gynoglossum , is known only from northern Epirus “ in aridis alpestribus ad fortem Bofcikopoulon district. Pogoni.5, It is characterized (and differentiated from S. scardicus) inter alia by the nearly sessile fruiting calyx. S. starnineus (Desf.) Wettst. ap. Stapf in Denkschr. Akad. Wiss. Wien, Math.-Naturw. Kl. 1. 88 (1885) is known from eastern Anatolia, Armenia, Syria, Iraq and northern and western Persia. Halacsy (in Magy. Bot. Lap. iv. 259 : 1905 and p0nsP- Fl. Graec. Suppl. i. 77 : 1908) records it from Mt. Chelmos in ^reece “ supra Sudena Achaiae.” This record needs confirmation. s}wnineus differs from S. scardicus in many characters including the position of the coronal lobes and the freedom of the filaments. S. apen - ninus (L.) Hohenack. has a fairly wide distribution in the Italian Peninsula, from the south to between 42° and 43° N., and in northern oicily. Early records for Corfu and Zacynthos have been questioned, but Hayek (in Denkschr. Akad. Wiss. Wien, Math.-Naturw. Kl. ^oix. 156 : 1924) gives it for Albania “ zwischen Buchengebiisch am Westabhange des PaStrik, zirka 1700 m.” The position of the coronal ^obes in S. apenninus is, as in S. scardicus , at the middle of the corolla- J*. It differs in the less exserted anthers and in the elevated margm to the uutlets ^ a n sc^^cus has been described above as biennial or perennial with Mes 8 Ti1 mark hidicating that some doubt is felt on this point. Prev,rS A stou anc* Sandwith'did not notice any old fruiting stems of ou 1Qus years on the plants of which material was collected and which hand^lT ^expect to find on a robust perennial herb. On the other Pro! }]le f ro°t8l°ck ” is thick and bears sometimes at least two and the *1 ^ °^en Several more stems. If they are not perennials some of con are unusual habit for biennials. The inflorescence varies Sl erably, especially with age. The lower half or more of the stem 4 is foliaceous, but has (in all the material seen) no axillary branches to the rather crowded leaves. Usually a little above the middle of the stem, the leaves subtend branches which bear the flowers either directly or more often after a little further branching. In young plants the whole inflorescence is dense, with the branches much shorter than the leaves, but in older plants, or on older stems, the branches have elongated to give the appearance of a rather loose panicle. — W.

The following note on the habitat of this grass has been contributed by the collectors : “The grass grows abundantly in three of the ravines which descend to the village of Voskopoj from the mountains rising immediately to the south-west. These mountains are of the serpentine formation ; their slopes arc mostly bare and stony, except for scattered pine trees and bushes of juniper and box. They possess an interesting flora of rare and local species which are mainly confined to the serpentine ; for example, Gypsophila spcrgulifolia Griseb., Linum hologynum Reichb., Fumana Bonapartei Maire et Petitm., Minuartia Baldacoii (Hal.) Mattf., Thymus teucrioides Boiss. et Sprun., Centaurea ptarmicifolia Hal. ex Hayek (C. epirotica Hal., non C. epirota Hal.). Streams rush down the gullies and are bordered by masses of the pale lilac flowers of Pinguicula hirtijlora Ten. The Brachypodium grows on undisturbed serpentine rock along the stream-beds of these gullies, but it was also traced as far up as the summits of the mountains at. their head, and here it attains an altitude of about 1500 m. The grass reappears in the serpentine gorge east of Gjergjevice, about three miles south of Voskopoj . Finally, it was found in great abundance in an exactly similar habitat, but at a lower altitude, near Boboshtice, south of Kor^e. This locality extends the distribution of the species considerably, since it lies at the base of the Morova Planina and is separated from the Voskopoj mountains by the plain of Kor^e ; the distance from Voskopoj must be at least twelve miles as the crow flies. It was noticed that the Brachypodium is found only on bare, untouched, serpentine rock, where it grows in great abundance and is frequently un¬ accompanied by any other species of phanerogam ; it was never seen on loose rubble, nor does it grow on the sandstones of neighbouring slopes. Other grasses found associated with it in August 1935, and not yet identified, were species of Sesleria , Agrostis, Avcnastrum, Molinia , Koeleria , Poa , Bromus , Fcstuca and Brachypodium (possibly B. pi natum). The area in which this species grows had not previously been explored by botanical collectors, although the serpentine region (Kamia, 1 opit) lying only a day’s journey to the north has been visited by .Markgraf and by Bourcart.” 3 Brachypodium serpcntini C. E. Hubbard does not show obvious affinity with any other species of the genus. Its densely caespitose habit, very short rhizomes, simple culms, entire leaf-sheaths of the innovations, setaceous filiform leaf-blades, pallid spikelets, minutely pubescent rhachilla, and 5-6-nerved lemmas serve to distinguish it readily from the five species recorded by Hayek from the Balkan Peninsula (see Hayek, Prodr. FI. Penins. Balcan. in Fedde, Repert. Beih. xxx. No. 3, 216-218: 1933). If the inflorescence be excluded, then B. serpcntini bears a distinct resemblance to certain species of Festucdj more especially to those of sect. Variae Hack. The caespi¬ tose habit, the anatomical structure of the leaf-blade, and the entire sheaths of the innovations are characters often met with in species of that genus, whilst the colour of the spikelets, texture of glumes and lemmas, are somewhat similar to those of F. jlavescens Bell. The inflorescence is, however, that of a typical Brachypodium. The type- specimen is in the flowering condition, but mature racemes were gathered in 1935 by Messrs. Alston and Sandwith. In these only a small percentage of the florets contained caryopses and in quite a number of cases the anthers had been only partially exserted. It seems probable that the scarcity of seed and the non-completion of anthesis were connected with the prolonged drought during the summer of 1935. The few caryopses available are somewhat similar to those of other species of Brachypodium. They possess the same elongated linear hilum, whilst the starch grains are simple and rounded and thus characteristic of the subtribe Brachypodinae. Saint- Yves in his Contribution h l’Etude des Brachypodium (Europe et Region mediterraneenne) ” (Candollea, v. 427-493 : 1934) has adopted Ascherson and Graebner’s (Syn. Mitteleurop. FI. ii. I 631-640 • 1901) division of the genus into two sections, I. Eu- Brachypodium Aschers. et Gracbn. (l.c. 631: 1901) and II. Trachynia (Link) Nym. (Consp FI Europ. 843: 1882), whilst Rouy (FI.

Corolla pink.” This striking plant was recently described (Kew Bull., l.c.) as the type of a new genus, distinct both from Costera and from the Philippine Iaera H. F. Copeland. Dr. J. J. Smith, however, informs the writer that he has received material of several new species, exhibiting com¬ binations of characters which manifestly break down the supposed generic distinctions between Costera, Iaera and Cymothoe. A paper on Costera (sensu lato) by Dr. Smith will shortly be published in the Buitenzorg Bulletin : it is therefore unnecessary to go into further details here. The writer is much indebted to Dr. Smith for bringing the matter to his notice and for kindly proposing to make the necessary transferences under joint authorship. Some justification may be offered for referring this genus to the 1 hibaudieae, the better-known and more “ typical ” members of which have large, conspicuous, brightly coloured flowers. There seems little doubt that we arc dealing with a much reduced type, whose evolution may be illustrated (and possibly more or less indirectly represented) by the series Thibaudia — T hemistoclesia — Sphyrospermum — Costera, etc. The feature which at once singles out this line of development from the great bulk of the tribe is the absence of the characteristic articulation between pedicel and ovary. Costera (inch Iaera and Cymothoe) is the 3 only Old World genus so characterized, and therefore, from a phyto- geographical point of view, extremely interesting.

It appears to be most closely related to the Philippine J . Cumingii Merr., which differs in its broadly ovate leaves, almost truncate at the base, and in its much shorter inflorescences.

Brisb.). The systematic position of the genus Heterachne Benth. requires reconsideration. Bentham (Hook. Ic. PI. xiii. 39 : 1877) placed his new genus in the tribe Festuceae (sensu lato), and stated that it was allied to Ectrosia R. Br. and Elytrophorus Beauv. Later (in Benth. et Hook. f. Gen. PI. iii. 1188 : 1883), whilst retaining Ectrosia and Heterachne in the Festuceae , he referred them to different subtribes, namely, Ectrosia to the Eragrosteae and Heterachne to the Meliceae. Hackel (Engl. u. Prantl, Nat. Pflanzenf. ii. Abt. 2, 70: 1887) treated both genera as members of the subtribe Meliceae. Heterachne differs from Ectrosia by its awnless lemmas, but resembles it in possessing sterile florets above the fertile, a character which no doubt greatly influenced Hackel in associating these genera with Melica Linn. This classification is, how¬ ever, a very unnatural one. Melica is a temperate genus, differing from both Heterachne and Ectrosia in having 7-9-nerved convex lemmas. In my opinion a more satisfactory arrangement is to place the last two genera with Eragrostis in the tribe Eragrosteae with which they agree in the possession of 3-nerved lemmas. In studying Australian grasses, a number of cases of cleistogamy have already been noted, and it appears probable that it occurs also in all species of Heterachne , as, in dissecting mature florets, the very small anthers have been frequently found still enclosed in the floret at the apex of the caryopsis.— C.

Only one specimen of Iseilema dolichotrichum was collected, but its apparent rarity was no doubt due to the exceptionally dry conditions prevailing during the summer season of 1930-1931 . Duchess is situated in extremely arid hilly country, broken by rocky gullies. The main vegetation consists of a fairly close covering of a spiny-leaved grass (Triodia sp.), whilst the gullies are fringed with trees of Eucalyptus and Melaleuca. It was along the banks of such a gully that the new species was found growing in association with various other annual grasses* such as Perotis rara R.

Cook District : Gilbert River, Wildash. Gregory’s specimen from Sturt’s Creek was cited under Anthistiria membranacea Lindl. by Bentham (FI. Austral, vii. 543). Two species of Iseilema , I. calvum C. E. Hubbard and I. vaginijlorum Domin, were growing in abundance at Jardine Valley, near Hughenden, and ample material of each was gathered for examination. Amongst a large number of specimens of I. calvum , two plants (Hubbard and Winders 7173B) were found which are probably the product of hybridi¬ zation between the above two species. In general habit they closely resemble I. calvum , but in other respects they approach I. vaginijlorum. The longer more slender pedicels of the involucral spikelets being bearded at the base recall those of the latter species, whilst the larger male involucral spikelets with firmer glumes are more characteristic of the former. One important feature which serves to emphasize the relationship to /. calvum is the 1-3-nerved lower lemmas ; these organs being nerveless in all other Australian species with the exception of that species. The genus Iseilema * Anderss. comprises about 16 species, seven ot which occur in India, Ceylon, Burma, Siam and Indo-China, whilst the remainder are confined to Australia. It forms, with Themeda Forsk- (Anthistiria L. f.) and Germainia Balansa et Poitrass., a well-defined * Ilackel (DC. Monogr. Phan. vi. 681 : 1889) points out that Iseilema is nout^r and that Anderason was in error in treating it as feminine. Andersson’s mistake has been porpetuated by many other botanists. 3 group of the Andropogoneae which Stapf has named the Themedastrae (Prain, FI. Trop. Afr. ix. 8: 1917). These genera are characterized by the few-noded, much-contracted solitary racemes, and by the homogamous male or neuter lower pairs of spikelets which form a false involucre around the 1-3 fertile spikelets and the male or neuter pedicelled spikelets. Iseihrm may be readily distinguished from Themeda , as each raceme is articulated with its peduncle and falls away as a whole at maturity, whereas in Themeda the involucral spikelets are persistent and the remainder of the raceme is deciduous. The Australian species are found throughout the Commonwealth with the exception of Victoria and Tasmania and the southern part of Western and South Australia, but are most abundant in the tropical or subtropical drier parts of the continent where the major portion of the rainfall takes place in the summer months. Queensland possesses bv far the greater number of species, as all those at present known from Australia, with the exception of I. trichopus , are to be found in this state. Several species are widely spread, whilst others, as far as is known at present, are rather local in their distribution. I. meiubTauaceum occurs over a very wide area extending from Camooweal and Mt. Emu Plains Station in Northern Queensland to the southern part of New South Wales and the northern part of South Australia. I. vaginiflorum has a still wider distribution stretching from northern Western Australia through Northern Australia to Queensland and southwards to New South Wales and South Australia. It does not appear, however, to be so common in N.S. Wales as I. me.mbramceum. The other species are confined to the tropical portions of Australia and, with the exception of I. calvum and I. trichopus, are at present known only from the Burke and Cook Districts of Queensland. The Australian species of Iseilema are frequently associated with the Mitchell Grasses (Astrebla S™ the open grassland of the downs and plains, growing in bare place! on is etwcm the tu"* °f th' In Australia these grasses are collectively known as “ Flinders Grass " but they have also been called “ Landsborough Grass,” “ Red Gulf termed ‘‘IbLll FT T fecently L mcmbranaceum has been wh lsfr Sna l;ndcrs “ Rud Flinders Grass,” whilst C l.

Flinders Grasses respond quickly to the summer rains which occur from January to April ; they make rapid growth and soon reach maturity. 4 From an economic point of view the Flinders Grasses are exceedingly valuable to sheep and stock-owners in the drier and warmer parts of the Australian continent. They are usually described as excellent fodder grasses and are often reputed to be more palatable than the renowned Mitchell Grasses (Astrebla spp.). Some species are more fragile than others but all break up when dry. The broken fragments of all species are said to provide much forage which is relished by stock, whilst frequent reference is made to the fact that sheep even lick up the small pieces from the ground (Everist in Queensl. Agric. Journ. n.s. xliii. 377-382 : 1935). The correct interpretation of the structure of the spikelets of Iseilema is far from obvious. The involucral spikelets usually consist of two glumes, a hyaline nerveless scale, 2 lodicules and 3 stamens, with occasionally a rudimentary ovary. Such a structure is indicated in the diagram given on tab. 3284 (I. Windersii). The dotted lines denote the missing parts. The hyaline scale, which is the lemma of the lower floret, might at first be thought to represent the palea of the upper floret as it is opposite the lodicules. That this latter interpretation is incorrect, is seen when a comparison is made with the corresponding scale in I. calvum. In this species the scale is 1-3-nerved and very like the upper glume. The number of nerves at once leads one to the con¬ clusion that it is not a palea and that it must be the lower lemma. The upper floret is thus without lemma or palea, although a rudiment of the former is sometimes present. The fertile spikelet is usually described as hermaphrodite, although Hackel (DC. Monogr. Phan. vi. 678 : 1889) was doubtful as to this point, for he writes in describing this spikelet (v. interdum $?)” and “ Stamina (sp. fertilis) non vidi.” In all the Australian species the fertile spikelet is female and no traces of stamens, other than rudimentary filaments, have been found ; but m the Indian species some of the fertile spikelets are definitely her¬ maphrodite. The racemes are subjected to considerable compression, owing partly to crowding and partly to being more or less confined in the spathes and floral sheaths. This compression has caused reduction in the size of some organs and suppression of others. In the species dealt with below, various stages of reduction are encountered, the most noticeable being in the involucral spikelets of I. vaginijlorum. These are sterile and mostly reduced to the lower glume, or the latter may be much reduced in size or even completely suppressed. Ihe seed” is usually composed of the whole raceme which dis¬ articulates from the peduncle at maturity, the involucral spikelets serving to protect the central fertile spikelet. In a few cases, however, the fertile spikelet has been found to disarticulate from the rhachis ; in such cases it has no pungent bearded callus as have species of Therneda- Ihe racemes are very light and in many species possess a basal tuft of hairs which no doubt assists in dispersal by wind, although since the introduction of sheep the presence of an awn provides the raceme with an additional means of dispersal. The distribution of these grasses is being extended towards the coast by the spread of “ seed 99 along stock- 5 routes and railway tracks by means of sheep and other animals. In 7. vaginijlorum the spikelets are almost wholly enclosed in the floral sheaths, which become indurated at maturity and finally detached from the inflorescence, thus forming a special type of seed.

Good characters are readily found to maintain a strict A. longicauda though the specimens gathered here under A. paucijugum do not, it must be confessed, main¬ tain the same high degree of homogeneity. Hooker’s A. longicauda possesses the following characters : — 1. The greyish green, almost glaucous blade. 2. The 2-4-jugatc fronds. 3. The terminal pinna usually long-caudate. 4. Sori nearer to the margin of the pinna than to the midrib. 5. The angle between costa and lateral nerves ranging from 37°-43°. 6. Stipe apparently shorter than the blade. On the other hand A. paucijugum may be distinguished as follows : — 1. The blades are dark green in colour. 2. The fronds are simple or 1-jugate. 3. The terminal pinna is acuminate but not long-caudate. 4. The sori are not nearer the margin than the midrib. 5. The angle between costa and lateral nerves ranges from 48°-65°. 6. The stipe is as long as or longer than the blade. It has been suggested above that A. paucijugum is not so homo¬ geneous a species as one might wish. In general characters the speci¬ mens resemble one another fairly well, but certain differences in the rhizome scales lead one to wonder whether some of the plants may possibly represent juvenile states of other well-known species. We have in Asplenium, unfortunately, a genus which is notoriously difficult to catalogue. Christensen has indicated this very clearly in hlS Pteridophyta of Madagascar, pp. 85-86, where he points out the astonishing degree of variation occurring in many of the species aim suggests that the genus may be passing at present through a period ° rapid development. * In the present case, one has, at any rate, clarified the position 0 Asplenium longicauda Hk., and whether A. paucijugum represents a taxonomic unit or merely a morphological state, is a matter for future investigation. A. longicauda in the strict sense is found only in Fernando Po, Princes Island and Gaboon. A. paucijugum, on the other hand, enjoys a muc wider distribution, from French Guinea in the west, through the Go Coast and central and east tropical Africa as far as Madagascar in t east. — F.

Johnstoni was the first representative of the tree Senecios of the African equatorial mountains to be discovered. It was collected by Sir Harry Johnston during his expedition to Kilimanjaro in 1884, and was described by Daniel Oliver in 1887 in the Transactions of the Linnean Society. In the light of the knowledge which we have to-day, it is obvious that the name covered more than one species. Oliver pointed out, indeed, that the two specimens of inflorescence at KeW showed important differences in the form of their capitula. For 35 years, however, any tree Senecio observed or collected on Kilimanjaro was referred to S. Johnstoni . It was not until after the well-known paper by R. E. and Th. Fries on the Senecios of Mt. Kenya and the Aberdares had emphasized the presence of several species on those mountains that a second species, S. kilimanjari, was detected by Dr. J. Mildbraed amongst the material in the Berlin Herbarium. But the true position with regard to the occurrence and distribution of the species on Kilimanjaro was only realized after the publication of the third one in 1930 (Kew Bull. 1930, 108). Of this species (S. Cottonii)f the most striking and perhaps the most abundant of the three, magnificent illustrations showing the habit had already been published by Engler under the name of S. Johnstoni . After the discovery of S. Cottonii a detailed questionnaire with regard to the many discrepancies in the literature was sent to all botanists likely to be interested, and as a result ample material with valuable notes were received at Kew. By means of these it has been possible to elucidate the problems presented in the old accounts and to correct the errors which have occurred in nearly all papers, including that in K.B. 1930. It is now known that there are three very distinct species on Kilima¬ njaro, and that these occur in zones in different ecological habitats, namely, in the forest, the subalpine zone and the high alpine zone* The species are, moreover, quite distinct from those at corresponding altitudes on other mountains. These high mountain Senecios are, in fact, comparable to island endemics, being separated by mountain plateaux instead of by seas. The uppermost species, which are the most specialized, are very distinct ; the lower species have more m common with each other, but by general consent they are, with one or two doubtful exceptions, sufficiently distinct to be regarded as separate species. Of the latter group, S. Johnstoni on Kilimanjaro is one of the most marked, and very distinct — with the possible exception of a form on Mt. Meru only 70 miles distant — from those on all other mountains* v Most of the references in the literature to S. Johnstoni on Kilimanjaro, and all the records of its occurrence on other mountains, refer to otne species. S. Johnstoni occurs as isolated trees or in small groups from abou 2550 m. to 3000 m., in very moist ground or actual water channels, 1 the uppermost part of the forest belt. It is confined to the shade, being found either in the forest itself, or forest islands, or in ascending tongu®^ of forest which fringe the ravines. This being the case, it is not ^ conspicuous as those which occur on the open mountain side. 3 result, it has, since Johnston’s time, been generally overlooked by botanists, a fact which largely explains how the name has become associated with, or indeed actually transferred to, each of the other species. In common with the forest species on other mountains, S. Johnstoni is less striking in appearance and less grotesque than the alpine forms. It shares with them the habit of a small forest tree, well branched and possessing a slender trunk with shoots bearing small rosettes of relatively thin leaves. The mass of marcescent foliage characteristic of the upper species is absent. The large, erect inflorescence is lax and the capitula are small and campanulate. These characters separate it at once from S. kilimanjari (3300-3600 m.), and still more so from 8. Cottonii (3450-4200 m.). From species occupying the same altitude on other mountains it is distinguished by the large, ovate or orbiculate- ovate leaves with cordate base, and by the long, slightly winged petiole (A very similar plant but with thin leaves tending to be elliptical with or without a cordate base, has been discovered by Mr Greenwav in a particular area on Kilimanjaro. The taxonomic status of this plant is uncertain and the diagnosis of S. Johnstoni has not been modified to include it.) — A. D. Cotton. Fio. 1, under surface of mature leaf, x & ; 2.

Johnstoni , was described by Mild- braed in 1922. No flowers were available, but the leaves afforded good characters. His paper has been largely overlooked and apparently Engler did not accept his view (Pflanzenwelt Afrikas, Band 5, Heft 1, p. 265). Recent material confirms the validity of Mildbraed’s species, and the specimens he cited have been verified and found correct. His statement, however, as to the altitudinal range must be modified, since it covered also the uppermost species ( S . Cottonii). S. kilimanjari occurs in boggy meadows and in ravines in the sub- alpine zone and is apparently plentiful above Moshi since abundant material from this area exists in the Berlin Herbarium. It is the species which occurs in the bog at about 3300 m. on the track from Marangu to Peter’s Hut, and was illustrated by the writer (Kew Bulletin 1930, 108). Being distinct from S. Cottonii it was at the time regarded as a form of S. Johnstoni. The species apparently seldom flowers, since no fertile material exists at Berlin, and, though specially sought for by various botanists during the past four years, no good flowers were observed until 1934, when they were collected and forwarded to Kew by Mr. P. J. Greenway. From S. Cottonii , to which it is clearly allied, it differs in certain small but definite and constant particulars. The leaf characters which separate it are the much less dense indumen¬ tum of the lamina, the very marked marginal rim of white woolly tomentum interrupted only by the hydathodes, and the petiole con¬ sisting of a short, very broadly winged leaf base. In S. Cottonii the very dense indumentum of the lamina is uniform, and the exceedingly long, stout petiole is not winged. The floral differences consist in the smaller capitula, with about 100 flowers instead of 150, the fewer involucral bracts and the conspicuous ray florets the ligules of which are reflexed. Greenway notes, moreover, that the flowers are lemon- coloured, whereas those of S. Cottonii are orange. The two species overlap at Peter’s Hut but no trace of intermediates has been found. A. D.

Hitchcock and the writer on Kilimanjaro in September 1929. They were recognized by Dr. J. Hutchinson as representing a new species and were described jointly by him and Dr. G. Taylor of the British Museum, the latter institution possessing specimens collected two years previously for the Washington Herbarium by Messrs. Piemeisel and Kephart. The species was regarded by the Engler school as a form of S. Johnstoni , as may be learned from the letterpress to Engler’s photo¬ graph of a group of trees (Die Pflanzenwelt Afrikas i. Heft 1, t. 18), and elsewhere he states “ die letztere Art (S. Johnstoni) ein sehr ver- schiedenes Aussehen liber 4000 m. und bei 2900 bis 3000 in. zeigt- . . . phaenotypisch . . . nieht genotypisch ” (op. cit. v. Heft 1, 265). . It is remarkable, however, that practically no material of such a striking plant had been collected, especially as it is perhaps the most abundant of the three species, a single gathering at Paris and another at Amani being the only herbarium specimens in existence before 1927. Since its description in 1930 it has been collected and photographed repeatedly, and ample material now exists in European herbaria. With the aid of the additional specimens the original description, especially as to the leaf, has been amplified and emended. . . The features distinguishing S. Cottonii from S. hlimanjari , which occurs in the zone below it, have been given under that species and need not be repeated. The plant is characteristic of the high alpine zone and commences at about 3450 m., continuing to the limit of general phanerogamic vegetation, i.e. about 4200 m. Isolated weather-beaten specimens may occur above that level. It is a water-loving species occurring in ravines, bogs, or shallow pools, the surface of which in the upper altitudes is often frozen over during the night. The plants are usually shorter than the two lower species, though at about the middle of the zone, between Peter’s Hut and the saddle in the Mawenzi direction, very fine specimens, tall and sometimes well branched, may occur. Engler’s illustration also shows very tall but less-branched specimens. — A. D. Cotton.

Mr. Gillett in his notes states that in the neighbourhood of Hargeisa it is “ a very common and widespread species.” Through the kindness of the Director of the Botanic Gardens at Berlin, the specimen has been compared with the type of Barleria proximo Lindau, and has been found to agree very well with that species. The slight differences between some of the measurements here given and those of the original description are without significance. B. proximo is characterized by its spines being arranged in fours on very short stalks, by its hairy eglandular spine-tipped calyx segments, and by its two-lipped corolla which is bright-yellow with a crimson throat and is shortly pubescent outside. Mr. Gillett collected another specimen (no. 4147) which is very closely allied to B. proximo, and which may prove to be a variety. It differs in having the spines on consider- a > e stalks, and in having lemon-yellow flowers without a crimson throat. — E.

Barleria quadrispina Lindau was described from sterile material. Uarke (l.c.) gives a description of the flowers, apparently based on B. linearifolia Rendle, a species which he had incorrectly reduced to the synonymy of B. quadrispina , and which has two-lipped corollas and narrowly lanceolate calyx segments. It is practically certain that Roth 487 in the Kew Herbarium is the same species as that described by Lindau, and Gillett 3994 also agrees very closely with the type of B. quadrispina. Both these specimens have flowers which are sub- equally five-lobed, and subulate tips to the calyx segments. The specimen here figured and described is from this latter gathering and is slightly less hairy than the type, whilst in Dr. Roth’s specimen the indumentum is rather more plentiful. B. quadrispina is closely allied to B. waggana Rendle and B. setigera Rendle, both of which occur in the same area, and agrees with them in having a small subequally five-lobed corolla. It differs in its more spiny habit and shorter internodes, and in the calyx being entirely glabrous. The type specimen of B. setigera Rendle var. pumila Rendle is too incomplete to make its identification with B. quadrispina certain, so I refrain from quoting this variety as a synonym. — E.

The most striking morphological features of Cuphea Hintoni are the long, ascending, straight spur and the peculiar disk. As indicated above, it is readily distinguishable from C. avigera Robins, et Seaton, which was hitherto known only from Pringle’s no. 4349, collected near Lake Chapala in the State of Jalisco. Mr. G. B. Hinton has now sent specimens of this species (no. 2661) from Tejupilco, District of Temascaltepec, State of Mexico, collected in a wet barranca. Dis¬ section of a young flower shows that the disk is represented by a small knob just behind the ovary. This could not be found in an older fruiting stage. The present plant, as shown in fig. 8, has a most remarkable disk, modified to form a nectariferous gland projecting into the spur. In this case the disk is adnate to the calyx for an appreciable distance, and, as the flower fades, the free portion withers and drops off. The pedicels of C. Hintoni show very minute bracteoles, which are in some cases almost obsolete, and have the appearance of small tufts of hairs. Koehne (in Engler, Pflanzenr., Lythrac. 80 : 1903) recognized twelve sections of Cuphea , of which the last, Diploptychia , included three subsections. Of these, Ornithocuphea , including only C. avigera , was described as having no disk, and ebracteolate pedicels, by which it was separated from subsections Trichoptychia and Leioptychia. In view of these facts, the writer has thought it advisable to separate C. avigera and C. Hintoni as a distinct section, to be distinguished from section Diploptychia by means of the straight, ascending spur, adnate disk, and relatively few ovules, as follows : — Sect. Diploptychia Koehne . — Discus manifestus, liber, parvus, deflexus; ovula satis numerosa, plerumque 10-30 sed usque 62 (fide Koehne) ; calcar breve, incurvum ; pedicelli manifeste bibracteolati. Herbae perennes, erectae, plus minusve lignosae. Sect. Ornithocuphea ( Koehne ) Bullock , emend., status novus.— Discus calyci adnatus, parte libera subobsoleta vel filiformi et elongata ; calcar pro rata elongatum, rectum, adscendens ; pedicelli minutissime vel subobsolete 1-3-bracteolati vel bracteolac nullae.— Herbae annuae, baud lignosae, caulibus basin versus procumbcntibus radicantibus. — Cuphea subsect. Ornithocuphea Koehne, l.c. 88, 179. The formation of adventitious roots on the procumbent portion of the stem in both C. avigera and G. Hintoni bears no relation to the insertion of the leaves. These roots are strictly confined to the lower side of the stem. In some cases the testa of the seed is still attached 3 to Mr. Hinton’s specimens, and it can be clearly seen that the primary root system, developed from the radicle, remains very small, the chief absorptive organs being the later developed adventitious roots.

Palmer 93 (U.S.). The taxonomic position of Hintonia presents something of a problem, so long as the old method of segregating the tribes by means of the presence or otherwise of winged seeds is rigorously maintained. Port - landia , with exalate, angulate seeds, is placed in the Condamineae , whilst Coutarea with winged seeds is placed in the Cinchoneae. It may be safely said, however, that the only character in which Hintonia / 3 approaches Coutarea is in the winged seeds. These are descending in Hintonia, but almost vertically ascending in Coutarea. In addition, the capsules of the two genera are markedly dissimilar. The flattened obovate, loculicidally dehiscent capsule of Coutarea is typical of the Cinchoneae , whilst the ellipsoidal, scarcely flattened, strongly ribbed, septicidal capsule of Hintonia is similar in general appearance to that of Portlandia. The latter, however, is loculieidal, and is usually crowned by the persistent calyx. Examination of the corolla in the three genera concerned shows even closer agreement between Hintonia and Portlandia , as contrasted with Coutarea. The last genus usually has a curved tube, often gibbous near the base, and contorted aestivation ; Hintonia and Portlandia have straight tubes, never gibbous at the base, and plicate-valvate aestivation (the scarious margins of the lobes overlapping in an imbri¬ cate manner). The stamens of Coutarea are exserted, and have strongly arcuate filaments; those of Hintonia and Portlandia are included and have straight filaments. The leaves, though not here regarded as presenting characters of prime generic importance, also afford useful indications. In Portlandia they are leathery and shining, whilst in Coutarea and Hintonia they are thinly herbaceous ; in the latter, however, distinctly longer petioles are found.

Many of the specimens cited show fruit only, and these vary con¬ siderably in size and in the number and size of the corky lenticels, which, the writer is convinced, are of great taxonomic importance, at any rate specifically. A few of them may actually belong to var. leiantha. There seems to be no doubt that Sess4 and Mocino’s Coutarea latiflora, described from their drawing by De Candolle in the Prodromus, has been wrongly identified by later authors. The drawing and descrip¬ tion of the fruit are definitelv indicative of the later described Portlandia pterosperma S. Wats, and not of the plant accepted by Standley as Coutarea latiflora The presence of conspicuous lenticels is decisive. 1 he native name “ copalchi ” given by De Candolle is almost universally app !c to / ortlandia pterosperma, and rarely to Standley’s “ Coutarea latiflora , which is more usually called “ quina ” or “ falsa quina.” The native names are probably reliable, since the bark of both plants is of value- copalchi for malaria, lung affections, aud for pinto, and quina as a febrifuge. ihe greater part of both drawing and description is equally applicable to both plants, the only feature definitely suggestive of Standby’s 5 “ Coutarea latiflora ” rather than Portlandia pterosperma being the absence of bracteoles. In the latter, these are very small and com¬ paratively early deciduous, and might be easily overlooked unless their presence or absence is known to be important. It is suggested that Sesse and Mocino, not realizing their importance, neglected them, whilst De Candolle, at once observing a specific character, wrote “ . . . pedicellis ebractcatis.” The balance of evidence is therefore strongly in favour of the identi¬ fication adopted above, Portlandia pterosperma becoming a synonym of Hintonia latiflora, and Coutarea latiflora DC. sec. Standi, receiving the new name Hintonia Standleyana. H. latiflora var. leiantha Bullock (vide p. 1). The specimen (Hinton 1258) from which the figures of the flower have been drawn is so strikingly different from the type of Watson’s Port¬ landia pterosperma that it was at first decided to describe it as a dis¬ tinct species. It was realized, however, that the material available for study at Kew was inadequate, and through the generous loan of the material in the United States National Herbarium the writer has been able to examine a very large series of specimens, most of which had been used in the preparation of the North American Flora. These show most remarkable gradations in nearly all the characters usually con¬ sidered to be of specific importance, and, taken in conjunction with the extensive geographical distribution, given in some detail above, indicate that the present plant is no more than an extreme form which is, how¬ ever, worthy of varietal rank. The variety is a shrub about 6 feet high, bearing large axillary white flowers. According to Mr. G. B. Hinton, the macerated leaves are taken internally for malaria, and boiled in a bath for the pigmentation disease known as pinto. The vernacular name given by Mr. Hinton is “ copalche,” a name which, as noted above, is in general use throughout Mexico for the typical form. 2. H. Lumaeana ( BaiU .) Bullock , comb. nov.

Gualan, Beam 6365 (U.S.). An extremely variable species, particularly as to the amount of indumentum on the leaves, hypanthium, and the outside of the corolla. With an even greater geographical range, it is at once distinguished from H. latijlora (as here understood) by the small, almost smooth fruit, which is not obviously lenticellate. As pointed out above, the absence of bracteoles led to its confusion with that species. In the dried state the two species are readily separable by means of the colour difference noted in the key. II. Standleyana is used in Mexico as a febrifuge, and the vernacular name is “ quina,” or a variant thereof. 4. H. octomera (Hemsl.) Bullock , comb. nov. Coutarea octomera Hemsl. Biol.

This is an extension of the Mexican range (Oaxaca and Chiapas) given by Standley. Coutarea mexicana Zucc. et Mart, was rightly trans¬ ferred by Hemsley to Portlandia , in which genus it is retained by Standley. There are thus three species of Hintonia , one of Coutarea and one of Portlandia indigenous in Mexico, the fourth species of Hintonia being confined to Guatemala. — A. A. Bullock.

District of Temascaltepec, State of Mexico : Palmar, in a barranca, plant 1 m. high, July 1934 (fh), Hinton 6319 (type) ; Ixtapan, 1000 m., by the river, shrub 2 m. high, Aug. 1932 (ft. jun.), Hinton 1268 ; Tejupilco, 1340 m., in oak woods, shrub 2 m. high, Nov. 1932 (fr.), Hinton 2657. Bouvardia capitata is at once distinguished by its congested terminal inflorescence, which is not closely paralleled by any other member of the genus. The inflorescence is evidently a much contracted ternately branched cyme, the middle “ branch ” at each forking being formed by the main axis. Each flower is subtended by a membranous, more or less fimbriate involucel (fig. 5), homologous with a pair of sheathing stipules, the opposite leaf-laminae having become obsolete. The flowers with their involucels are combined in threes into partial inflorescences enclosed in a further larger involucel of similar form, as shown in fig. 4. Here two rudimentary leaf- (or bract-) laminae are present. The partial inflorescences are again combined in a similar manner, and again the involucral leaves (bracts) increase in size at the expense of the sheathing stipular base. This process is repeated until the bracts assume ordinary leaf-form, and the stipular sheath is reduced proportionately. An intermediate stage is shown at fig. 3. The minute bracteolar appendage shown in fig. 5 is apparently not a constant feature. Small lateral inflorescences are occasionally produced from the axils of the uppermost pair of leaves, but this apparently is merely a case of predevelopment of branches which would otherwise remain dormant until the following year. On the old stems of the specimens examined, three, four or five branches arise from the same level, although in every case the leaves on the young shoots are strictly opposite. This is due to the develop¬ ment of secondary buds at the extreme base of the axillary branches, so that at later stages the branches appear to arise from the same node on the main axis. Such buds can be seen in some cases. The writer has been unable to find any really close affinity for B. capi¬ tala. Applying Standley’s key (in FI. N. Amer. xxxii. 100: 1921), it falls within a group of species characterized by opposite (not whorled) >road leaves, relatively large, spreading (not erect) corolla-lobes, and glabrous or only slightly hairy corolla-tubes. It is not, however, closely related to any of the thirty species enumerated by Standley. A. A.

Temascaltepec, District of Temascaltepec, State of Mexico, a shrub 0-75 m. high, on a dry hill, 1780 m., 28 July 1932, Hinton 1131. Bouvardia cataphyllaris belongs to a very typical group of species characterized by erect or suberect corolla-lobes, in striking contrast to those of B. capitata , figured in plate 3296. It appears to be an erect shrub with the ultimate branches strict and slender. The flowering branches are lateral, arising from the axils of fallen leaves, and normally consist of four internodes surmounted by a 3-5-flowered simple cyme. The two lowest internodes are extremely short, and their presence is indicated by two cataphyllary sheaths, the lower being split into two parts, one on each side of the axis. The third internode is longer, and the two leaves at its apex, although small, are rarely reduced to the condition of cataphylls. The fourth internode is surmounted by a pair of normal, fully developed leaves, which often have solitary flowers in their axils. The axis continues for one internode as an inflorescence rhachis, bearing at its apex a pair of bracts and three pedicelled flowers. These bracts are often foliaceous, but are always much smaller than the uppermost pair of leaves, and are sometimes linear or even filiform. Filiform bracteoles sometimes occur on, the pedicels or at the base of the hypanthium, but are not constant. The calyx-lobes are sometimes very unequal and occasionally bifid. A. A. Bullock.

Vernacular name : “ Cirian Chino.” Although Basanacantha echinocarpa appears to be widely distributed in Mexico, it was represented at Kew by only two rather poor specimens ( Palmer, , 1885 coll., and Palmer , 1887 coll., no. 106) until Mr. G. B. Hinton’s excellent material came to hand. The only figure of this species hitherto published is very poor, and is inaccessible to the majority of students. The writer agrees with Prof. Bremekamp (Rec. Trav. Bot. Neerl. xxxi. 265 : 1934) in maintaining Basanacantha as a genus distinct from Bandia , which should be interpreted in the strict Linnean sense, with B. aculeata L. as the standard-species of a comparatively small and entirely American genus. The name of the present plant is accordingly changed to Basanacantha echinocarpa , in spite of the fact that the flowers, as shown by Mr. Hinton’s specimens, are not alwrays dioecious. Mr. Hinton states that variability in this species is not pronounced in his area (i.e. Temascaltepec, Mexico, Huetamo, Michoacan, and Coyuca, Guerrero), where the plant is frequent at altitudes below 1300 m. The seed, which is embedded in pulp, is edible, while the shell of the fruit is used medicinally. — A. A.

Few travellers have failed to notice it and dried specimens have been accumulating for many years, but without ripe fruit it was impossible to assign the plant to any known genus, although the large coloured bracts of the involucre suggested Cephaelis in the wide sense. Mr. T. G. Tutin, who took part in the Cambridge University Expedition to British Guiana in 1933, has made the present description and figure possible by his collection of spirit material of the large blue fruits. A close examination of the plant shows that it is nearer to Cephaelis as understood by most authors than to any other known genus, and it runs down to Cephaelis in Wernkam’s Key to Tropical American Rubiaceae in Journ. Bot. liv. 326-334 (1916). Moreover a close allv has been discovered in Cephaelis Duckei Standley in Field Museum, Publ. Bot. viii. 374 (1931), a plant of forests near the mouth of the Amazons in the State of Para, Brazil, and represented at Kew by a photograph of the type and by a duplicate specimen of the type collection (Ducke 18828). It is unfortunate that Standley ’s description leaves out several important details of floral structure, and that the Kew material is insufficient for dissection, but it is obvious at a glance that it must be associated with C. potaroensis , and no other species has been seen which presents any such affinity. C. Duckei has the leaves, stipules, orange-coloured bracts and large shaggy white corollas of the British Guiana species, but is easily distinguished by the villous branchlets with spreading, downward directed hairs, and by the possession of a less reduced inflorescence. This, in the Kew specimen, is composed of 8 involucral bracts which surround 4 flowers ; but it is almost certain that more than 4 will be found in future specimens. On the other hand, in all the numerous specimens of C. potaroensis the involucre is normally composed of 4 (very rarely of 5) bracts, and the inflorescence is a reduced simple sessile dichasium of 1-3 flowers. Up to the year 1934 this plant might well have been placed in Cephaelis without further hesitation, but in that year there appeared an extremely important account, accompanied by a separate paper with critical notes, of the Rubiaceae of Surinam (FI. Surinam, iv. 113-298; Rec. Trav. Bot. N6erl. xxxi. 248-308). In this the author, Prof. C. E. B. Bremekamp, gives an original and necessarily revolutionary treatment of the genera of the Psychotrieae . The Psychotria and Cephaelis of Bentham and Hooker’s Genera Plantarum are broken up into a number of new or revived genera, and the result a far more natural grouping of species with similar facies and habit than was attained by Muller of Argau in the Flora Brasiliensis (1881) or by K. Schumann in the Pflanzenfamilien (1891). A large number of characters have been used in the key, drawn from many parts of the plant, and it is obvious that, if they are by no means of equal value, t oy are at any rate based upon important morphological considerations. eP re^cnt plant has been carefully studied in relation to this valuable wor which, it must be remembered, is concerned only with species occurring in Surinam. It differs (a) *rom restricted Cephaelis Sw. in the absence of bracts and 4 bracteoles from the individual flowers (a single bract or bracteole has been found in one instance) ; in the ring of hairs near the base of the corolla-tube ; and in the shallow furrow on the flat side of the pyrene. Perhaps one may add the different position of the stamens in the long- styled (near the middle of the tube) and short-styled (near the throat) flowers, since Bremekamp describes the insertion of the stamens of Cephaelis as “ inserted midway in the tube.” (b) From restricted Psychotria L. in the form of the inflorescence, and in the ring of hairs near the base of the corolla-tube. (c) From Palicourea Aubl. in the form of the inflorescence, and in the corolla-tube which is not swollen unilaterally near the base although it possesses a ring of hairs. (d) From Schumann’s Uragoga L., sections Hiantocalyx and Codono- calyxy in the normal absence of bracteoles and of a second series of bracts, in the form of the calyx, and in the ring of hairs at the base of the corolla-tube. Other genera were much less closely allied, both in facies and in taxonomic characters. It became apparent that the nearest generic affinity of the Potaro Valley plant was with Cephaelis (sensu stricto), and this conclusion has been provisionally accepted by Prof. Bremekamp to whom the above description, with notes, was submitted. He believes, however, that the absence of bracts and bracteoles, the shallowness of the furrow on the flat side of the pyrene, and the small number of flowers in the inflorescence would justify the creation of a new genus. The present writer does not feel qualified to take this step. In the first place, a proper generic description could not be drawn up without a thorough investigation of the morphology of the inflorescence of Cephaelis Duckei , which is certainly congeneric, but adequate material of that species is not yet available. Secondly, if — as one hopes — Prof. Brcmekamp’s researches are to be extended to cover the whole of the lropical American Psychotrieae , a thorough examination of all the described species must be undertaken, before the differential value of morphological characters for taxonomic purposes can be completely understood. It might be discovered, for instance, that several other species with few large flowers which have been placed without adequate description in Cephaelis will help to constitute a new or revived genus by the side of C. poiaro'ensis and C. Duckei. On the other hand, a slight re-widening of the limits of some genera might be found desirable or at any rate convenient. It is evident that only a specialist in Rubiaceae wi lave the requisite knowledge and time for this work and, accord¬ ingly, the 1 otaro Val ey plant is described and figured for the present as a species of Cephaelis N. y.
