158 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [6. Leprieurif 
own spathe, not callous at the axilla, somewhat arched and flexuose, spreading or 
recurved, flattish, 8-10 cm. long (the uppermost slightly shorter than the lower ones) 
with 19-20 flowers on each side; spathels infundibuliform, narrowed a good deal at 
the base, rather approximate and with the base of the one partly included in the 
one below, not very distinctly striately veined, entire at the mouth and extended at 
one side into a very acute and patent point; involucre cupular, rather deep, almost 
totally concealed in its own spathel, very obliquely truncate externally, very acutely 
two-keeled and almost two-winged, bi-dentate and deeply emarginate on the side next 
to the axis. Male flowers perfectly bifarious, inserted at a rather acute angle and half 
concealed by their respective spathels, elongate, very slightly falcate, very acute; the 
calyx tubular-cylindraceous, slightly striately veined, with three short acute triangular 
teeth; the corolla one-third longer than the calyx with acute segments, polished 
externally.—Other parts unknown. 
Hasirat.—Sierra Leone: in swampy places near small streams on the laterite 
plateau of Falaba (Scott Elliot No. 4460 in Herb. Berol). 
OsnsERVATIONSs.— Of this species I have seen only a specimen of one partial inflores- 
cence and the upper portion (35 cm. in length) of a leaf. This same specimen 
was regarded by Prof. O. Drude (l. c.) as belonging to €. Baríerii, from which 
however it differs in the different arrangement of the leaflets, which in C. Barterii are, 
as in the Asiatic C. gracilis, distinctly clustered into a few patent spreading groups, 
and besides are thin and almost herbaceous in texture. In (€. /falabensis the leaflets 
are simply inequidistant, rigid and firm in texture, and inserted at a rather acute 
angle. C. Heudelotii seems to me a nearer ally to C. falabensis than €. Barterii, but 
of C. Heudelotii the female plant only is known, while we have only the male of 
falabensis, and consequently it is difficult to make an exact comparison of the two; 
but in €. Heudelotit the leaflets have the nerves naked beneath and only the mid- 
costa is spinulous, while in C. falabensis 3 nerves are spinulous beneath. It differs 
from C. Leprieurit, of which the male spadix much resembles that of @. falabensis, 
in the faleate male flowers and in the more rigid and more inequidistant leaflets.

Description.— Very probably scandent and not of large size. Stem . . . 
Leaf-sheaths . . . . . Leaves short, 35-40 cm. long, not cirriferous ; patiolé® 7-10 
em. long, rather thick, subcylindric and longitudinally wrinkled (when dry), more or 
less covered with greyish, removable, furfuraceous scurf, armed beneath and at the 
sides with some strong, straight, horizontal, dark-tipped spines; rachis more or less 
furfuraceous as is the petiole, rigid, and relatively thick, acutely bifaced above, 
roundish beneath, where armed one. the middle with solitary, straight, horizontal or 
slightly deflexed spines, which change into small claws towards the apex; leaflets 
rather many and crowded, inserted at an angle of about 45°, more or less inequidistant 
or interruptedly equidistant, being sometimes, mainly near the apex, divided by short 
vaeant spaces into 2-3 groups, where each leaflet is regularly about 15 mm. apart; 
furthermore the leaflets. are papyraceous, narrowly lanceolate, somewhat attenuate to
