DzscRrPTION.— Probably scandent and of moderate. size. Stem . . . , . Leaf-sheaths 
* + + +, Leaves not seen entire, but probably cirriferous; petiole . . . . . (apparently 
very short); rachis in its basal portion slightly convex above, where very densely 
covered with unequal spines, some of them very short and tuberculiform, whereas others 
are 10-12 mm. long, scattered, solitary or aggregate, straight and erect on the surface 
or slightly deflexed, subulate, brownish with a light base, rather closely armed at 
the sides with slightly hooked prickles, slightly convex and quite smooth underneath; 
leaflets in the small basal portion seen by me inserted along a narrow longitudinal 
furrow at the side of the rachis, subequidistant, 3-5 cm. apart, alternate or sub- 
opposite, papyraceous, rigidulous, glabrous, rather opaque, subconcolorous on both 
surfaces, narrowly ensiform, gradually tapering towards a very narrow base, acuminate 
from the middle into a setose apex, 30-32 em. long, 15-20 mm. broad, with 3 
bristly-spinulous very distinct costae above; underneath, the nerves tenuous and 
naked; transverse veinlets very slender, rather crowded; margins ciliate with 
spreading rather strong spinules, the lower ene in the upper surface bordered by a 
shining stripe. Male spadizx . . . . . Female spadiz decompound, apparently large and 
diffuse (not seen entire), terminating in a small slender tail-like, sheathed, aculeolate 
appendix (this 9 em. long), with many approximate partial inflorescences; primary 
spathes (the lowermost not seen by me) tubular-cylindraceous, closely sheathing, slightly 
enlarged above, thinly coriaceous, greenish (when dry), almost polished, sprinkled 
with small brown scales (visible under a lens) entire and truncate at the mouth, 
where prolonged at one side into a triangular dorsally keeled and sparsely aculeolate 
point, otherwise unarmed; partial inflorescences inserted at the mouth of their own 
spathe with a distinct axillary callus, the largest amongst the few of the upper part 
of the spadices seen by me, 20 em. long, with 4-5 distichous spikelets on each 
side; secondary spathes sprinkled with brown scales, unarmed, elongate-infundibuli- 
form, narrowed towards the base, where flat or slightly concave on the inner side, 
rounded on the hack, obliquely truncate at the mouth, scarious and ciliate-paleaceous 
at the mouth, slightly prolonged at one side into an acute point; spikelets inserted 
just at the mouth of their own spathe with a distinct axillary callus, arched, 
spreading, 5-7 cm. long with about 6 flowers on each side; the upper ones 
somewhat shorter; spathels infundibuliform, narrowed a good deal towards the base, |
