There can be little doubt that Mr. F. M. Bailey, to whom Kew is indebted for material of Galbulimima, was justified in referring: nae Homoxy ecretory cells containing oil occur in t sophyll of the leaf; and the endosperm is oily, containing protein and oil, but no starch. Oily endosperm is a character o ede, as to cause partial septation. This feature shows agreement with the tribe Magnolieae.t Small peltate scales are present on the lower side of the mature leaf, and are abundant on the inflorescence and young parts. Peltate scales appear not to have been found hitherto on any member of the Magnoliaceae, but they occur in certain Anonaceae and Monimiaceae.’ Th uliar appearance of the fruit, which is said to resemble that of a Callitris, is due to the unequal development of the carpels. In a fruit composed of nine carpels, for example, only three or four * Journal de Botanique, vol. xiv. Pp. 259 (1900). ft Solereder (Syst. Anat. Dicot., Engl. ed. p. 30) mentions that ‘ more or less distinct septation of the pith by diaphragm-like groups of sclerosed cells’ is characteristic of the Magnolieae, 3 Fie. 1, flower-bud; 2, section through same; 3, scales outside calyx; 4, petal; 5 and 6, stamens; 7, staminode ; 8, pistil and torus; 9, transverse section through same; 10, fruit; 11, transverse section through the fruit; 12, endocarp and an old ovule (inverted). All enlarged except 10 and 11, which are of natural size. N.B.—Most of the stamens in the fully expanded flower are relatively longer and arrower than in 5 and 6. The syncarpous appearance of 9 is due to the carpels being closely pressed against one another. * Pilger in Engl. & Prantl, Nat. Pflanzenfam. Nachtr. III. p- 109; Dalle Torre & Harms, Gen.

The capsule of Honckenya is terete and bristly all over, whereas that of Cephalonema has a broad wing opposite the middle of each loculus, and the bristles are confined to the margins of the wings. In Hone onckenya the loculi are subdivided by incomplete transverse septa between the seeds; these are wanting in Cephalonema. ep. According to Gentil, quoted by De Wildeman (Not. Pl. Util.

The genus Isoberlinia, one of the three species of which is here figured, may be distinguished from Berlinia by the longer panicles, the smaller subsessile flowers with a short receptacle, and more particularly by the five petals being subequal, shortly unguiculate and subequal to or only slightly exceeding the sepals. : The description of the pod is added, doubtfully, from a specimen collected by Mr. G.

The union of 2 the filaments, however, appears to be a character of sufficient importance to justify the formation of a new genus. The stamen bundles vary in number between 8 and 16 and it seems likely that the number increases by the splitting up of some of the coalescent portions as the flower becomes older, but even in fully opened flowers the bundles are quite distinct and have numerous free upper portions each bearing a bilocular anther. The arrangement and structure of the whole androecium support the view that the bundles represent united, not branched filaments. Throughout the family Myrtaceae we find a number of scattered genera with the stamens aggregated in phalanges, but as a rule the number of phalanges is definite and each phalange has a definite orientation with regard to a petal. In Tistania, for example, there are 5 groups of stamens opposite to the petals. For the material on which this account of the genus Pareugenia is based Kew is indebted to that distinguished naturalist and statesman Sir Everard im Thurn, K.C.M.G., by whom it was met in the course of his official duties while Governor of Fiji and High Commissioner of the Western Pacific. To his field note we owe our knowledge of the habit of the species ; the precise locality in Fiji in which the specimens were collected has not been recorded.—W. B. TurRRILL.

This circumstance probably accounts for the misinterpretation of its taxonomic position in the Genera Plantarum, again at t. 1180 of the present work, and once more in the Natiirlichen Pflanzenfamilien, which it is the object of the present description to adjust. The very characteristic hairs of the indumentum suggest a comparison of a species with Bor. oraginaceous rather than with Apocynaceous pl: and closer study of its salient characters aka it to be a Héiokaphaw 2 n which genus it is one of a group of probably four closely allied but bide distinct species aggregated by Bentham in the Flora Australiensis, vol. iv. p. 399, under H. tenuifolium, r. e contrast emphasised in the differential diagnosis is with specimens from the Gulf of Carpen- taria collected by Brown which form the basis of his species. If the printed label which accompanies the specimen delineated (Mr. Gosse’s xpedition. Interior of South Australia. Comm. R. Schomburgk, May 1874) could be taken literally, mh locality in which H. Gossei was collected ought to lie somewhere between the Mann and the Musgrave Ranges or within the latter range.

When Pierre described Plagiostyles (l.c., p- 1326), he said: ‘Au sommet latéral de la loge unique, on voit deux ovules collatéraux et anatropes 4 opercule trés petit, dont un seul devient fertile. L’ovule stérile prend la forme d’un petit disque induré et reste appliqué contre la graine tout prés de son funicle.’ This was in 1896. Later on, in 1899, he distributed specimens of Plagiostyles with this note ‘ Quand jai publié ce genre (Soc. Linn. Par. p. 1326) n’ayant . . . des fruits 3 ispositi 5 B 8 The case in question is illustrated by figs. 12 and 14. The funicle of the aborted ovule and that of the perfect one which developed into a normal seed sprang side by side from the normal point of attachment. The former was free and could easily be lifted up; the latter, in the mature seed, was adnate to the seed, forming its raphe. Hardly less remarkable is the transformation 3 which the ovary undergoes ee cies aa In the flower the and its orientation is in the tonigttadizal axis of the pistil. After that the longitudinal axis gets so displaced as to lie eventually at right angles to the pedicel with the persistent stigma at one end, whilst the seed experiences a displacement of its parts corresponding to figs. 9 and 10. The outer integument develops into a mainly crustaceous shell, the testa; the inner assumes oe pro- portions on the side opposite to the raphe and becomes of a spon consistence, with the sadrieee formation e lacunae wich are often large and irregular.—O.

From Kaempferia it differs in the lateral staminodia being rudimentary or suppressed, and from Costus in its acaulescent habit. Another species, C. spectabilis, Fenzl, which has been figured in Curtis’s Botanical Magazine, t. 7992, is ‘widely spread in the eastern half of es from Senaar southwards to Nyasaland, and differs from the present plant in its larger size, obovate-cuneate (more rarely suborbicular) leaves, and comparatively shorter and broader corolla- tube.

Kick’s Usambara specimen* has smaller, less coriaceous leaves with shown in the raceme next to fig. 5 of the plate, is that the lowermost one or two bracts are foliaceous, rather smaller than the leaves and with more pronounced nervation, but otherwise similar, possessing distinct vagina and adnate stipules. The lamina is sometimes considerably reduced, in one case practically to the midrib, so that it becomes subulate, but the vagina and stipules are hardly altered. The upper bracts are triangular, acuminate, under 0-5 cm. in length, and have neither vagina nor stipules. Only two species of Berberis are known from Tropical Africa, and one from Arabia. B. Petitiana, C. K. Schneider,t from Abyssinia, possesses the same foliaceous bracts as B. Holstii, and may have to be united with it when better known. B. Forskaliana, C. K. Schneider, a native of Yemen, appears to be specifically distinct, but its flowers are not yet known.

Portuguese East Africa ; Mozambique, in poor sandy soil near watercourses in flat savannah country near the Madanda Forest, Dawe, 431. In the Northern Transvaal, where it bears the native name ‘ muchuss,’ Entandrophragma. caudatum is a tree about 30 feet high. In Mozam- bique, however, where it is known as * mazozo, attains a height of 60 feet, and the trunk a circumference of 6-7 feet. According to Mr. Dawe’s notes made in the field it appears however to be some- at rare. The caudate-acuminate leaflets distinguish EH. caudatum from the other species. According to the classification adopted in Engler & Prantl, Die Natiir Tishaa” Pflanzenfamilien, H. caudatum should be referred to the genus Wulfhorstia, on account of having only 6 ovules in each loculus, and no partitions inside the staminal tube. Entandro- phragma has 8 or more ovules in each loculus, and the basal portion of the staminal tube is joined to the disk by means of 10 thin partitions. These partitions are very short, however, in H. speciosum, Harms, so that the generic difference between Entandrophragma and Wulfhorstia practically rene the presence of 3 ovules in each row instead re being hardly a generic character. Wulfhorstia may be retained, however, as a section of Po ee comprising Fic. 1, flower; 2, the same, petals removed; 3, pistil, disk and interior of staminal ‘tube ; - lo frag tudinal pai of pistil and disk; 5, Wansverte section of ovary; 6, ca ; 7, seed; 8, body of seed, and embryo ower part of a cotyledon, with iadicls and plumule.

Perrier de la Bathie. In the case of P. Thouarsii, there are at Kew two sheets of fruiting specimens, collected by the Rev. R. Baron in ‘ Central Madagascar,’ which the writer has no hesitation in referring to the species as defined by Roemer and Schultes. The follicles of Baron’s specimens are 20-23 em, long and about 7 mm. wide, and 3 have found to match with some specimens of Boivin’s. Their leaves are considerably larger than those of Petit Thouars’ plant and their venation is said to be ‘ bien visible en dessous.’ The inflorescence and the flowers, including the corolla, are described as slightly pubescent, and the corolla lobes as somewhat shorter than the tube and rather broad. In view of the differences indicated, some element of uncer- tainty as to the identity of their plant with that of Petit Thouars still remains. ‘The plant collected by Guillot, on the other hand, has been compared and identified by M. Hochreutiner with the plant of Thouars, which is the basis of the description drawn up by Hochreutiner. Baillon in Histoire des Plantes, l.c., says of Plectaneia, of which he knew but one species, viz. P. Thouarsit, ‘ fauce squamulis 5 cum staminibus alternantibus subobturata.’ Such scales or tubercules are shown in fig. 3 of this plate. But sections made through the corollas of P. Thouarsii as well as P. elastica show that the walls of by Baillon for throat scales such as exist in various other Apocynaceae. Neither Jumelle and Perrier, nor Hochreutiner mention such bodies in their descriptions of species of Plectaneia. According to Professor Jumelle and M. Perrier de la Bathie, P. elastica yields a rubber of good quality. They state that 1 litre of the latex of ‘ piraovaovao ’ yields 16-18 grammes of dry rubber. The Sakalaves cut the stems down in order to obtain the rubber, but the French authorities suggest that old stems which reach 20 cm.

Although appa- rently identical in their vegetative parts, the two species may be readily distinguished by a remarkably interesting difference in the form of the inflorescence. male spike with two very short lateral branches at the base, which bear the female flowers. During the flowering stage of the male these and bear fruit. In the fruiting stage the large scar left by the male at the point where it articulated is always plainly visible in the sinus of the two infructescences. It seems probable then that the females become fully developed either at the end of the season and are pollinated by flowers from younger inflorescences, or at the begin - ning of the next flowering season when fresh male flowers are matured on other parts of the plant. e growth of the two species under cultivation has been observed to be different: the primary branches of S. Jenmani are directed upwards and form an acute angle with the stem, whilst those of S. cladogyne spread from it almost horizontally —J. Hurcuinson.

It agrees on the whole with the Oe ae of that family given in Bentham and Hooker’s Genera Plantaru but differs from all the other genera in its dichasial cymes. The external appearance of the ovary and fruit recalls Lophira Oe ; and the filaments resemble those of some Dipterocarpaceae. Mr. L, A Boodle, who has kindly examined material, reports that the anatomical characters of the leaf and stem are not specially distinctive. They are such as might be found in members of a ptéain ee of different families, one of the latter being the Ternstroemiaceae. The anatomy does not agree well with that of the a one ne important difference being the absence of cortical bundles in S According to Engler’s latest scheme of Mimaibalick: * Sladenia should be referred to Parietales-Theineae, but cannot be assigned to any of the families included in that group. When mature fruit and seeds are known, it may be necessary to found a new family for its reception. Examination of young fruits suggests that the fruit may split septicidally into three cocci. Gil escription, referred Sladenia tentatively to Dilleniaceae, in which he also included Actinidia, Saurawja and Clematoclethra + These three genera are, however, so distinct from the remaining Dilleniaceae, that it seems better either to leave them in Ternstroe- miaceae,t or to treat them as an independent family viper Sladenia cannot be retained in Dilleniaceae in either case, as ae little in common with the subfamily Dillenioideae—T.

Hiern in 1873 in his monograph of the family Ebenaceae, p lished in the emer ton of the Cambridge Philosophical shove (vol. xvii, pars 1, p. 65). No name is there bestowed on the genus, which, when susovuineie taken up by Dr. Giircke in the Pflanzen- familien, was termed Rhaphidanthe, the manuscript name which Hiern had inscribed on the sheets in the Kew herbarium containing specimens collected by Mr. G. Mann in the Rio Muni Territory. These 2 specimens have only male flowers and Hiern knew only flowers . = sex. But Giircke, who has treated Rhaphidanthe as, so far, a typic genus, has attributed to the solitary species, R. obi sinjolia, fruits of an oblong-ovoid shape, 15 cm. long. This circumstance indicates that Giircke had access to fruiting specimens obtained by some collector other than Mann, and the nena! is that these fruiting specimens were some collected by Soyaux on the Sibange Estate in the Munda district, about 50 miles to the wiih of the locality in which Mann’s plant was found; these Soyaux distributed as his n. 238. The example of Soyaux, 238, at Kew has been written up ‘an Rhaphidanthe Hiern MSS ?° and a fruiting twig of this songee is here figured (figs. B, 5-9).« The plant of Soyaux is so like that Mann that there can be no doubt as to their being congeneric. There is, however, considerable doubt as to their being conspecific; the leaves of = csibenge plant are much smaller and are uniformly sparingly hairy beneath. The characteristic papillae which impart a uniformly glaucous specs to the underside of the leaves in Mann’s specimens are, in the plant of Soyaux, confined to certain patches of epidermal cells ; they are absent from relatively wide areas along the nerves and veins, which therefore show up more distinctly. The conclusion to which the facts point is that Soyaux n. 238 represents a — species, closely allied to R. obliquifolia, based on Mann n. 1800, w ay be known as R. Soyauxii, and may be described as follows : _ R.

Soyauzii afford an opportunity of supplementing the description of the genus Rhaphidanthe if it were certain that the genus could be maintained. This, however, is in any case questionable; if we accept the genus Diospyros as circum- scribed by Hiern in his monograph and by Giircke in the Pflanzen- familien, it is indeed inadmissible, because there is no character left ourselves led to the section Noltia, the basis of which is N. tricolor, Schum. & Thonn., a plant known only from the Gold Coast, and, imperfect as our acquaintance with that species is, there seems little doubt that Rhaphidanthe approaches the Gold Coast plant more nearly than it does any other species of Diospyros. But Noltia is a rather heterogeneous group and may, like the genus Diospyros itself, have to be revised and readjusted. Such a readjustment is, however, beyond the scope of the present note, which has as its aim the bringing - together all that is known at present regarding Rhaphidanthe.— O. Starr. A.

This species was originally placed in Threlkeldia in Chenopodiaceae by but moved it back to Chenopodiaceae assigning it a place next to Threlkeldia in Chenoleae. Volckens in Engler and Prantl’s Natiirliche Pflanzenfamilien enumerates it at the end of Chenopodiaceae as a genus of doubtful affinity. In the writer’s opinion there can be no doubt that its affinity is with the Gyrostemoneae in Phytolaccaceae. It shares with them all the vegetative characters to a high degree and also the structure of the seed, apart from the extreme reduction of the aril. It appears, however, highly specialised in that it possesses only one carpel which develops into a peculiarly shaped hard nut. he rudimentary perianth is open on the side facing the supporting leaf, but is otherwise of the same nature as in the other Gyrostemoneae. e stout, cavernous and ultimately quite hollow style which is open upwards, and has a much divided fringed stigma, is very peculiar, but the stigmatic character finds its counterpart in Tersonia, although the somewhat fleshy or waxy divisions are less numerous and more regularly arranged in that genus. Although reduced to a single carpel, the gynaecium of Cypselocarpus shows traces of the symmetry of the carpels of its polymerous allies. The very light and yet hard- shelled smooth fruits seem to be equally well adapted for transport by wind (rolling) and by water —O. Starr.

In some of the specimens obtained by Mr. Forrest in 1914 a few of the lower leaves are entire 2 and in one gathering only entire leaves are present so that the plant bears a considerable resemblance to those specimens of M. laneifolia, Franch., in which the central raceme-like cyme, which is normal in that species, is replaced by a number of simple 1-flowered radical scapes. In M. lancifolia we have the same grey anthers that occur in M. concinna, so that care has to be exercised in discriminating between the abnormal simple-scaped state of the former and the abnormal entire-leaved state of the latter.

Three stages in the evolution of the androecium may be traced in both genera: 1, stamens all free; 2, stamens united in five phalanges alternating with one or more free filaments ; 3, stamens arranged in phalanges which are connate below in a staminal tube.

Spatalla is a genus of small erect or spreading Proteaceous shrubs endemic to the Cape, and with a single exception, S. barbigera, Knight, confined to the South Western Region of the Colony. 5S. barbigera extends into the Prince Albert Division in the Karroo. The genus 2 as defined in the Flora Capensis contains 21 species, but as understood by the earlier authorities, such as R. Brown and Meisner, it embraced 5 others, two of which occur in the Karroo. These ive species eee been made by Phillips the types of a separate genus, Spatallopsis, on account of their strictly actinomorphic as opposed to slightly zygomorphic perianth, and of slight differences in the ovary and stigmatic disk. The species here figured, S. squamata, Meisn., is remarkable in the genus Spatalla in having conspicuous, more or less membranous, glabrescent involucres, which are provided with a curious line of hairs inside below the middle lobe; another distinct feature is the spirally coiled and reflexed anticous (abaxial) = segments with their long-appendaged limbs J.

There is, no doubt, a considerable superficial resemblance between the two genera ; but the former has panicoid and the latter typically poaoid spikelets, as was pointed out by Hackel himself. The affinity of Poecilostachys lies clearly with Oplismenus, Beauv., from which it differs in its slender, 3 laterally much compressed spikelets, its similarly compressed fertile floret and its thin valve and valvule. e awns are also less developed respects. In the Kew collections 5 species referable to Poecilostachys are present. k Their characters are set out in the following key :-— Spiculae omnes vel saltem nonnullae aristatae, glumae (saltem superior) spiculam mediam plane superantes.

Several inflorescences (some of them with the uppermost leaf attached to the peduncles) collected by A. Whyte in Nyasaland on the Masuku Plateau, between 6500 and 7000 feet, may represent another species of the genus described here. The panicles are less distinctly secund, the tips of the glumes more herbaceous and spreading, and the spikelets more gaping during flowering, thus imparting a slightly different facies to the plant. There is also frequently a g flower with the lower floret. The name is intended to indicate the more or less herbaceous nature of the outer parts of the spikelets (xAoy, herb ; &yvy, chaff)—O. Srapr.

From Sierra Leone to the Sudan and southwards to Angola. The species was originally described from a specimen collected by Biichner at Malange, Angola. The only other species known so far to belong to Chasmopodium is C. Afzelii, Stapf, a grass confined to Sierra Leone and the lower Senegal, which is very closely allied to C. caudatum. The difference between Chasmopodium and Rottboellia (sens. angust.) is chiefly in the structure of the axes of the raceme and their adaptation to receive the fertile (sessile) spikelets. In Rottboellia each joint is fused with the adjoining pedicel, forming an anticously open receptacle in which the sessile spikelet is lodged. In hasmopodium, on the other hand, joint and pedicel are clearly separate, leaving an oblong open space between them, within which the upper glume of the sessile spikelet is exposed.—O. STAPF.

The standard specimen of R. gracilis consists of a bundle of closely packed, but separate simple culms; in other cases the primary axis 1s branched from the very base, forming a tuft of erect culms, each of them flowering. The latter growth-form seems to be usual for the allied R. triaristata, Stapf (Lepturopsis triaristata, Steud.), which 2 is, however, a more robust plant and also differs in the pepere of larger — with the lower glume very sharply wrinkled up to the broadly triangular more conspicuously ciliolate tip and with mostly 2-aristulate peat cels. I have followed K. Schumann in accepting Schweinfurth’s No. 2485 (the original of Hackel’s R. triseta) as identical with Steudel’s Lepturopsis triaristata, but I have not seen the original of the latter and am somewhat doubtful as to the correctness of with extravaginal innovations. I have not been able to find such or to see traces of a rhizome in the Kew specimen of Schweinfurth’s plant, which is merely a densely tufted annual. R. gracilis and R. triaristata are the only annual species of the genus, the others being typically caespitose perennials with closely pa ake aad , long, persisting basal sheaths and wiry culms.— O.

Angola; Malange District, Gossweiler, 807. Rhodesia: Livingstone, Craster, 33; islands in the Zambesi, near Victoria Falls, Gibbs (original) ; Rogers, 5315. Five species referable to Miscanthidium have been described so far, M. capense, M. Sorghum and M. junceum under Erianthus (see Flora Capensis, vol. vi. p. 322), M. teretifolium, which may be accepted as the standard species or type, and M. Gossweilert under Miscan- thidium (see Flora of Tropical Africa, vol. ix, part i. p. 89). MM. capense and M. Sorghum have also been referred to Saccharum by Steudel, and the former to Miscanthus by Andersson, whilst M. Gossweileri was originally described by Hackel as a species of Cleistachne. In ackel’s Monograph of the Andropogoneae only M. capense and M. Sorghum are accounted for. There they form a small group of Erianthus characterised by the tough axes of the panicle and the presence of a ‘‘perfect’’ awn. Circumscribed as above, Miscan- thidium agrees more closely with Miscanthus than Frianthus. Com- 0 M. junceum, Stapf, from Rhodesia, has been selected to represent the arrangement and structure of the basal leaves, which are very similar in both species—O. Srapr.

In dry, open situations and in deciduous forest and sunny jungle, locall abundant, often imitating small bamboos. J. D. Hooker, l.c. 177, has already pointed out that Bentham and Hackel were mistaken in their conception of Andropogon montanus, Roxb., and he placed the latter correctly near A. intermedius, R.Br., and A. odoratus, Lisb. (Amphilophis intermedia, Stapf, and A. odorata, Stapf). Hance’s specimen, quoted by Bentham from Hongkong under montanus, is a somewhat robust state of the spicigerous form of florum (A. villosulus and A. parvispicus, Steud.) and auvdy Amphilophis glabra, Stapf (Rhaphis stricta, Nees), and the description may be taken also to cover to some extent the plant figured here. Hackel dis- tinguishes two varieties of his ‘ Andropogon montanus’’—one with 3 species are of wide distribution, namely, C. glaucopsis and C. parvi- florum. The latter, which extends from North-West India to Japan, Australia and Polynesia, and westwards to Abyssinia, is the only one with a distinct tendency to marked racial differentiation, parti- cularly in the eastern section of its area. The other species referable to Capillipedium are C. Schmidii (Andropogon Schmidii, Hook. 1.), C. pteropechys (A. pteropechys, C. B. Cl.), C. Hugelii (A. Hugeli Hack.), C. filiculme (A. filiculmis, Hook. f.), and possibly one or two other as yet imperfectly known species. All these are confined to the Deccan and Rajputana.—O. Srapr.

Two other sheets, however, in Vanderyst’s collections (nos. 2661 and 3832) from the Kwango and Stanley Pool Dis- tricts of the Belgian Congo belong clearly to a distinct species of the genus, so that Diheteropogon is so far known from at least three species. The nearest approach to Diheteropogon may be found in Andropogon filifolius, and it is, in fact, a moot question whether it should not be transferred to Andropogon. Nees, led no doubt by a superficial resemblance with Heteropogon, actually described it as Heteropogon filifolius. It lacks, however, the extreme differentiation into homo- gamous and heterogamous pairs of spikelets which is so conspicuous a feature in Diheteropogon, although it possesses generally one or two homogamous pairs at the base of the peduncled or of both racemes, a character present in a less pronounced degree in most species of the section Piestiwm.—O.

Tropica, Arrica. Belgian Congo: Katanga, Homblé. Bentham in Journ. Linn. Soc. vol. xix. p. 101 (1881), pointed out the “ mixed ” character of the genus Cynodon, referring especially to the Australian species “ with the spikelets of M icrochloa, but with the 2 inflorescence of Cynodon.’’ Subsequently in Genera Plantarum, vol. iii. p. 1164 (1883), he emphasised this point and distinguished the ustralian group as a section, Brachyachne, from the rest of Cynodon (section Fibichia), adding these words: “sectiones . . . VIX non pro generibus propriis habendae,” and under Brachyachne, ‘‘Sectio a Microchloa vix nisi habitu et inflorescentia differt.” To those Australian species have now to be added M. obtusiflora, Benth., and the species figured here, both African. The spikelets of all those species imilar in struct d g t that they have to be grouped together in one superior unit, and this should be, in my opinion, of genericrank. The sharply keeled, not dorsally rounded upper glume, and the peculiar orientation of the spikelets, distinguish it from Microchloa and Rendlia, whilst the inversion of the proportion of the sizes of the glumes and the floret, as well as the delicate texture of the latter, exclude it from Cynodon. The rhachilla is continued more or less beyond the floret in all the species, as is also the case in Microchloa and Cynodon Dactylon, Pers., and C. transvaalensis, Burtt-Davy, but not in C. incompletus, Nees.—O.

Afr, . ii, p. 232, and Stapf in Fl. Cap. vol. vii. p. 593), whilst Pilger in Engl. Bot. Jahrb. vol. xlii. p. 95 proposed a new subgenus Herpodiplachne of Diplachne for the latter. But a complete revision of the genus Diplachne has convinced me that Odyssea has while at the same time it is easily recognised and remember : Diplachne Jaegeri, Pilg. 1.c. p. 94, from Lake Eyasi, East Africa, seems to be a third species of Odyssea.—O.
