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,

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.

The genus Cephalonema is closely allied to Honckenya, from which 
it differs principally in the capsule. 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.

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. C. Dudgeon at Zaria, which consists of two leaves 
and is accompanied by a sketch of the pod.—W. G. Crars.

Potynesi4 : Fiji ;. without precise locality, im Thurn, 262. 


The plant here described i is undoubtedly allied to Eugenia, a genus 
well represented in Fiji and other Polynesian groups. 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.

Australia: South Australia; Interior, without precise locality, 
Gosse. 


The material of this species available for study is very scanty. 
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. But Gosse’s expedition also covered 
considerable ground in the south-western corner of the Northern 

erritory (from Reynold Range to Mann Range) and extended for 
a short distance into West te so that the precise tonality of 
the species is doubtful—O. Sra

his plant is remarkable on account of the very rare, if not unique, 
occasional presence of a second ovule, the family of Euphorbiaceae 
ing otherwise very sharply divided into strictly l-ovulate and 
strictly 2-ovulate genera. 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

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. Sta

Pseudolachnostylis is a small genus of Euphorbiaceous shrubs endemic 
to Africa, and especially abundant in Angola and the Zambesi basin. 
‘ It is distinguished in the tribe Phyllantheae by its shortly pedunculate 
cymose male inflorescences and the hard globose tardily septicidal 
capsules. The female flowers are axillary and solitary or subsolitary.

The genus ee Fenzl, is intermediate between Kaempferia, 
Linn., and Costus, Linn., with the former of which it has been united 
by Bentham aa ‘with as ie by Schumann. 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. 


C. Dalzielii is said by Dr. J. M. Dalziel to grow all over Northern 
Nigeria, except in the north, but to flower only rarely. It is called 
in ov Sane language * takalmin zomo’ or hare’s slipper.—C. H.

This Crotonogyne is very distinct in appearance from the other 
species of its genus, though in floral structure it agrees well with its 


2 


congeners. The difference in habit is Ateely due to the eerie 
under which it grows. Like Homonoia riparia, Lour., an 
member of the same natural family, it is to be found only on ate 
in river-beds which are completely submerged when the rivers are in 
ood. The transfer of the species from Manniophyton, a genus in 
which the leaves are palmately lobed, to Crotonogyne, — is its 
—e. place, unfortunately precludes the continued use of the 
e C. angustifolia bestowed by Dr. oak in ~igiee upon shore and

Usambara, Kwai, 1700 m., Fick. 


The above description has been drawn up exclusively from Battis- 
combe’s specimen, which has also served as the type of the plate. 
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. 

The genus Berberis apparently originated in the Northern Hemisphere, 
and has penetrated southwards in America, Africa and Asia as far as 
Tierra del Fuego, Usambara and the Malay Archipelago respectively.

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

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. In

latex is brought about by the natives by exposure to the sun and subse-

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

The genus Sladenia was referred to Ternstroemiaceae by Kurz and 
Thiselton-Dyer, Il.cc. 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. A. Spr ce

The genus Euryops is represented in South Africa by about 40 species, 
all of which are endemic. Of the remaining species of the genus, 
five or six occur at high altitudes in the mountains of Tropical East 
Africa, one extending into Arabia; there is one species, which is 
endemic, in Socotra.

The plant here figured is taller and has longer and broader leaves 
than any other species of the genus. It was first collected by Mrs. 
Dieterlen in Basutoland, and subsequently a few pho were found 
by Mr. W. J. Haygarth on moist and almost inaccessible places on 
nearly i rocks on the sides of Amawahqua mountain near 
Bulwer in Natal

The genus to which our illustration relates was described by = 
W. P. 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. Soyauxii, Stapf; species nova R. obliquifoliae aflinis, sed foliis 
minoribus pro longitudine latioribus subtus undique parce pilosis, 
papillis epidermatis ad areas quasdam inter venulas sitas repressis

The characters of the fruit of 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.—

Soutn West AustraiA: In the interior, Drummond, 55, 438. 
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.

flank of the Li-Kiang range, 27°30’N, 3000 m., Forrest, 12796. 


This neat little species was first met with by Mr. G. Forrest in 1913, 
and in both gatherings of that year, to which belong the two specimens 
figured, all the plants have lobulate leaves. 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. If this care be exercised, however, the possibility of 


is long, simple and fusiform as in M. Forrestii, not short and tufted 
it i cinna. This species affects open stony or limy pastures 
and the ledges of limestone cliffs—D, PRatn.

M. concinna from Yunnan, with which it agrees as regards capsules,

According to Beccari, Malesia, vol. iii. p. 253, the only constant 
difference between Durio and Boschia is in the shape and dehiscence 
of the anthers ; these are reniform in Durio, dehiscing by a long curved 


2 


slit, and subglobose in Boschia, opening by a terminal, circular or 
elliptic pore. 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. 
The third type of androecium is characteristic of Boschia Mansoni and 
several species of Durio—T. A. SPRAGUE.

feature of the species, which is present also in a few others, is that the 
limb of the posticous perianth-segment is glabrous or nearly so, whereas 
those of the lateral and anticous segments are adorned on the back 
with a beard of long hairs. The plant appears to be of very restricted 
distribution, having so far been found only in the neighbourhood of 
French Hoek.—J. Hutcurnson.

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. Hurc

This species, which was discovered by Hildebrandt in 1877 and 
then found again by F. Thomas in 1896, was more recently (1910) 
collected by Mr. E. Battiscombe in excellent specimens from which 
the above description has been drawn up. ey are accompanied 
by the following note :—“ 207 Tana River. Poplar Tree. Deciduous. 
Very abundant on the banks of the river. Grows to a height of 60- 
80 feet, average 70 feet. Bark at first smooth, white, on old trees 
the bark is dark in colour, rough with deep fissures ; petioles twisted 
so that the leaves hang vertically. Wood soft, light, about 25 Ibs. 
a cubic foot, heartwood light brown. Coppices freely. Used by 
natives for ‘dug-out’ canoes. Altitude from 1500 feet to sea-level.”

one (G. Benthami, F. Muell.) is described from Queensland, and one 
from the New Hebrides, but till now G. ternata, A. Gray, has been the 


Kandavu, Lakemba, Ngau and Moturiki. It is a timber tree 40-50 
feet high and has scarlet flowers. : 

The species here figured was collected by Sir Everard im Thurn 
while Governor of Fiji, and was described, along with other novelties 
found by him, in the Journ. Linn. Soc. vol. xlii. p. 19. e native 
name is given as ‘common vunga’ and the collector states that it 1s 
this tree on which the little crimson parakeets are fond of feeding. —

Canary IsLANnpDs: Fuerteventura’ near a Burchard. 


The Flora of most of the Canary Islands has been comparatively 
well-explored ; but that of the two low eastern islands nearest the 
African continent, Fuerteventura and Lanzaroté, is not so well known 
as that of the others, chiefly on account of their geographical position 
and unattractiveness, consequent on lower altitude and more arid 
climate. It is not surprising, ‘Deaaclote. that an occasional new species 
is found in these islands, and still more might be brought to light by 
a thorough investigation during a whole season,

a shrub growing by rocky streams, J. M. Dalziel, 1000; Makump, 
120 m., N. W. Thomas, 933 


The genus Oncostemma was described and figured by Schumann in 
Engl. Jahrb. vol. xvii. p. 148, t. vi. fig. R-T. Although the description 
of that genus does not agree with Schumann’s figures, it seems to be 
the one nearest to that described here, which, on account of the erect 
opaque pollinia without pellucid margins, also finds a place in the tribe 
Marsdenieae. 


The nature of this outer corona (“corollinische corona” of Schumann 
in Engler’s Pflanzenfamilien, vol. iv. 2, p. ) in Dalzielia favours 


__ the pollinia in Dalzielia are cylindric-ellipsoid and not subglobose 
like those of Oncostemma. The shape of the pollen-carrier (cor- 
pusculum) is different in the two genera; in our genus it is obtusely 
Sagittate, projects between the two erect pollinia, and is equal to two- 
thirds their length. According to Thomas, D. oblanceolata is known 
in Sierra Leone as Nyinawe.—W. B. Turrtt.

can be found. More recently a sixth species, P. ecristata, Rolfe, a 
native of Florida, has been added, this being a plant that has occupied

The genus Alpinia as described by Schumann in the ¢ Pflanzenreich * 
contains a heterogeneous collection of about 140 species arranged in 
six sections ; several of these sections appear to be sufficiently distinct 
to be treated as genera. One of these groups is the genus Eriolopha, 
which includes about 16 species. It is peculiar to New Guinea and 


2 


a few adjacent islands, and is characterised by the large, broad and 
thick anther crest, which is also very hairy. In most of the species, 
if not in all, the development of the flower spike is very peculiar. 
The inflorescence, having developed to its full length or nearly so, 
produces spikes containing one or two flowers enclosed in long, stiff 
bracts. These spikes then elongate, as more and more flowers are 
produced, into a long cylindric spike covered with short, hard, 
imbricating bracts. I know of nothing like this form of development 
in any of the Zingiberaceae—H. N. Riviry.

The genus Poecilostachys was considered by its author to be allied 
to Lophatherum, and one of Hackel’s species, viz. P. geminata, was in 
fact described “originally as Lophatherum geminatum. 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.

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.

Although the close affinity of Danthoniopsis with Trichopteryx 1s 
beyond doubt, I have not been able to connect it more particularly 
with any of the known species of T'richopteryz. The more herbaceous 
texture of the glumes and valves, the readiness with which the lower 
floret disarticulates, and the peculiar wing-like appendage of the palea 
of the fertile floret seem to separate Danthoniopsis most generally from 
Trichopteryx, while the deeply bifid, transversely bearded valve of 
the fertile floret and its very short and obtuse callus distinguish it 
from almost all the species of Trichopteryx. T. Dregeana and its 
immediate allies alone exhibit a similar structure, but they have on

The standard species of the genus Coelorrhachis as understood here 
is C. muricata, Brongn. in Duperry, Voy. Coquille, Bot. vol. 1. p. 65, 
t. 14 (1829), which in 1833 was redescribed independently in Mém. 
Acad. Petersb. ser. 6, vol. ii. p. 250 as Coelorrhachis glandulosa, Trin. 
Coelorrhachis comprises twelve species, six of which are confined to the 
tropics of the Old World, and as many are found exclusively in the 
New World. Of the Rottboelliae of Hackel’s monograph the species 
numbered 17-27 belong here, with the exception of 20, 22 and 23, 
which might more appropriately constitute a distinct American 
genus, ranging from the central and southern United States to 
Brazil.—O. Srapr.

TroprcaL AFRICA. 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.—

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-

Inp1a, Curna, and Java. In India, from the lower Himalayas to 
16 N. lat. in the Deccan Peninsula, and eastwards through the Khasia 
Hills to Lower and Central Burma, thence to Siam, Tonking, Yunnan, 
Kwangtung, and the Yangtse Kiang valley: also in Java. 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.

A very similar plant was collected by Dybowsky in the French 
Gaboon in 1891, but the specimen is too incomplete to admit of its

precise determination. 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. Svar.

by the laterally much compressed spikelets and the peculiar shape of 
the fruiting floret, to which the tightly enclosed caryopsis conforms. 
The fruiting floret, or ‘ false fruit,’ is so much curved or gibbous on 
the back that it has even been described as semilunar. The back is

Xyochlaena comprises a number of species which might be classed 
either with Tricholaena or with Melinis if their characters were 


X. capensis (T. capensis, Nees), and possibly X. vestita (Panicum

and X. capensis are natives of the drier parts of South Africa, whilst 
X. vestita is confined to Socotra. They are, like X. monachne, emi- 
nently xerophytic grasses, and often found under conditions of desert 
type. The name Xyochlaena is intended to allude to the reduction 
or absence of the silky indumentum of the spikelets of T'richolaena. 
The epithet monachne has nothing to do with the genus Monachne 
of Beauvais, which is by his description and by fig. ix. of tab. x. of 
his Agrostographia a species of Friochloa, but is, by fig. x. of the same

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. Starr.

grass described here. In the course of time it has become connected 
with no fewer than nine mostly widely different genera—a veritable 
Odyssey, hence the name—but it may be hoped that it has at last 
reached a safe port. Bentham was the first to suggest an approxl- 
mately correct affinity, when he placed it in his new section Sclero- 


other species of the new genus mentioned above (see Rendle in Cat.
