‘or rounded at the apex and with an erose denticulate margin. Seed very irregularly 
globular and acutely angular, 10-12 mm. in diam.; chalazal fovea indistinct; albumen 
equable; embryo basilar, 
Hasirat.—Borneo; near Kutcingat Siul, in Sarawak (Beccari P. B. No, 23). 
OpsERVATIONS.—Of this very distinct species I have seen only one very incomplete 
specimen consisting of one leaf and a portion of a spadix as to which I am uncertain 
whether if it is simply decompound with very small partial inflorescences bearing very 
abbreviate spikelets, or if it is supradecompound with spikelets 3-4 cm. long and 
bearing few glomerulate flowers at each spathel. The main characters of this species 
are the leaflets with few, broad, 5-costulate leatlets; the very abbreviated spikelets with 
very closely packed secund flowers; the rather large fruit with a conical point and 
not furrowed scales, and the angular seed.

Description.—Gregarious, trailing at first, then not very high scandent, 3-6 m. 
long (€. B. Clarke). Sheathed stem 2-25 cm. in diam. or exceptionally 
smaller; naked canes 7-15 mm. in diam. with a polished surface.  Leaf-sheaths 
sometimes flagelliferous, more or less gibbous above, very densely covered with 
spines of two kinds; some of them large, 2-3 cm. long, narrow, flat, subulate, 
horizontal or deflexed, scattered. and solitary or more or less confluent and subseriate; 
others (by far the more numerous) much smaller and often reduced to sub-spiny bristles 
with a sub-bulbous base; all dark. brown, at least af, their apex, and with a 
light base.  Ocrea with a short ovate liguliform limb, 10-15 mm. long and densely 
covered with brown rigid bristles. Leaf-sheath flagella elongate, irregulerly armed 
with very unequal and sometimes long-tipped claws. Leaves comparatively short? | 
usually 6-1 m. in length, not cirriferous; petiole robust, channelled above 
in its first portion, flat upwards, rounded below, very irregularly armed at the 
margins with a few stout, straight, 1-4 cm. long, rigid, horizontal or deflexed 
spines, which are swollen or sub-bulbous at the base; in addition the petiole is 
rather densely covered throughout on both faces with small, short, straight spines, 
which are subulate from a broad conical base and sometimes reduced to small spiny 
tubercles; of this last kind of spine some appear also on the rachis, chiefiy at the 
sides; rachis spinulous on the upper aspect (or sometimes smooth ?) where it is acutely 
bifaced in the upper, and obtusely in the first portion, remotely armed beneath 
(where flattish near the apex and rounded in the remainder) with a few stout 
and long spines which, like those of the petiole, are sub-bulbous at the base but 
suddenly deflexed and intermingled with scattered solitam small claws; leaflets few,
