«allous above at thoii- insertion and also furnished beneath with another sometimes
distinct callus inside the basal plica, rather shortly and suddenly acumiiiate in a
slightly bristly-spinulous tip, papyraceous, rather firm, glabrous and dull on both
surfaces, paler beneath, with an acute mid-costa and a few slendei" side-nerve-* (juite
naked on both surfaces; margins acute, smooth, except towards the apex, where very
finely spinulous, often bordered in the upper surface with a polished band ; transverse
veinlets crowded, fine and much contiuuous; the side-leaflets 2o-30 cm. long and
4-5 cm. in width; those of the lowest group narrower (3-5-3 cai.) and those of
the terminal group shorter (17-20 cm.J but not narrower; the two of the terminal
pair confluent and forming a forked flabeilum. Male spadLc somewhat shorter than the
leaves, forming a rather dense cupressiform panicle, in one specimen with 7 approximate
partial inflorescences, terminating in a short tail-like appendix which is sheathed
-with aculeolate spathes; primary spathes tubular, the bwest elongate cm. long),
very closely sheathing, somewhat flattened, biconvex in section, with the edges
acute and quite smooth, obliquely truncate at the month and prolonged at one side
into a triangular acuminate point; upper primary spathes much shorter, thinly
coriaceous, cylindraeoous, slightly enlarged above, truncate and entire at the mouth
where prolonged at one side into a triangular acute point, armed with a few
very small rccurved aculei; partial inflorescences inserted inside the n;outh of their
own spathe, arising erect from these and then spreading and arched, furnished with
many eecoodary infloresceuces which gradually decrease in length and number of
spikelets from the base towards the summit; the largest secondary inflorescences have
various (6-7) spikelets oii each side and these also decrease in size and number of
flowers from the base upwards; the lowest partial infloresccnce 2(J cm, in length,
the upper ones gradually shorter; secondary and tertiary spathes infundibuliform
unarmed, finely striolate longitudinally, truncate at the mouth and prolonged at one
side into a triangular subulately acuminate point; spikelets slender, inserted at the
mouth of their own spathe with a distinct axillary callus, spreading or horizontal
slightly arched, comb-like when charged with flowers; the largest, the lowest, 2-3 cm
long with 13-15 flowers on each side, the upper ones gradually shorter; spathels very
rowded, bracteiform, concave and almost boatshaped, strongly striately veined acute
or obtuse; involucre cupular, truncate, entire, not distinctly two-keeled or bidentate
on the side next to the axis. Male flowers very approximate or one in contact with
the other, perfectly bifarious in one plane, almost horizontally inserted, oblongslightly
apiculate at the summit, 3-5 mm. long; the calyx thick in texture, black
when dry, indistinctly and coarsely veined, with 3 li-ht-bordered broad acute" teeth •
the corolla twice as long as the calyx, polished outside. Other parts unknown '

DESCRIPTION.—Scandent, of moderate size. Sheathed stem about 2 cm. in diam.
2-4 cm. Lauterbach. Leaf-shcatlts flagellifevous, light-gceenish when dry, gibbous
above, marke(i from the insertion of the flagella lower down with an obtusely raised
costa, rather densely armed with light-coloured spines of which some are very small and
subtubercuiiform and others laminar, slender, deflesed, of variable size, short or
up to 15-20 mm. long, these last usually present near the mouth. Leaf-sheath Jlagelhi
filiform, almost unarmed in their lower portion, higher up very densely covered with
very small usually scattered claws. Ocrea i-ather large, 8-10 cm. in length, liguliform,
obtuse, membranous, exsuccous and very finely spinulous on the axillary side
(between the petiole and the stem), and disintegrated into reticulate fibres or filiiments
on the outer side. Leaves not cirriferous, about 1 m. in length; petiole rather
short (12 cm, in ono loaf), rounded beneath, where armed near the margins and
along the middle with many small scattered prickica; rachis flattish above in the
lower third-part and bifaced upwards, convex beneath where armed along the
middle and at the sides, from the base to the summit, even between the two
terminal leaflets, with uniform, short, solitary, light-coloured or slightly brown-tipped
claws; leaflets not very numerous, in one leaf conspicuously approximate into 6 opposite
bundles of two to three pairs each with vacant spaces of 10-15 cm. between each
bundle; the leaflets are thinly papyraceous, rigidulous, dull and concolorous on both
faces, ensiform or very naiTowIy lanceolate-ensiform, somewhat narrowed to the base
where attached to the rachis with a small axillary callus, gradually acuminate from
the middle upwards into a tip, which is bristly spinulous at the sides, tricostulato
with the mid-costa acute and the side costao more slender, all three furnished above
with a few short fulvous bristles; beneath all the nerves less prominent and only the
mid-costa with a few bristly spinules towards the apex; margins not thickened, appressedly
spinulous; transverse veinlets very slender, much interrupted; the largest leaflets
up to 35 cm. in length and 2-2-5 cm. in width, but except those of tho terminal
group which are shorter they are all of about the same dimensions; the two of the
terminal pair confluent up to the middle and forming a small forked flabeilum.
Other parts unknown.

River, Lautsrhauh No. 1560, 24th Nov. 1S90, in the Berlin Herbarium.
OBSERVATIONS.—I have seen of this only one sterile specimen with a portion of
the stem and an entire leaf. It has the same kind of armature on the leafsheatha
as C. veslitiis and it is evidently closely related to C. ralumensis from which
it difiers in the densely spinous leaf-sheaths, shorter and obtuse ocrea, and in the
leaflets very distinctly approximate in bundles.
