the base, gradually subulately acuminate at the apex, opaque, slightly paler beneath 
than above, their mid-costa sparingly spinulous on both surfaces or smooth beneath ; 
the secondary nerves slender and naked; the transverse veinlets sharp, much 
interrupted; the margins rather closely spinulous, not or very slightly thickened by a 
marginal nerve; the largest 15-17 em. long, 15 mm. broad, the upper ones shorter ; 
the two of the terminal pair quite free at the base. Male spadiz flagelliform, very 
elongate, simply decompound, the one seen (wanting the base) | m. long and in 
addition produced into a rather long finely clawed flagellum; primary spathes very 
narrow-tubular, cylindraceous or somewhat flattened, strictly sheathing, chartaceous, 
sparsely aculeolate, obliquely truncate at the mouth and produced at one side into a 
triangular acute point ; partial inflorescences terminating in a caudate sheathed unarmed 
appendix, in the spadix seen by me 5 in number, of which the largest, the lowest, is 
30 cm. long with 7-8 spikelets on each side, the others shorter and with fewer 
Spikelets; secondary spathes elongate-infundibuliform, unarmed, finely striately veined, 
obliquely truncate and naked at the mouth and produced at one side into a broad 
triangular acute point; spikelets attached a little below the mouth of their own spathey 
narrower at the base than above (with the spathels there very closely imbricate, 
flowerless and smaller than higher up), flattened, arched, spreading, the largest 6 
em. long with about 12 flowers on each side, which are erecto-patent and half 
immersed in their own  spathels;  spathels very asymmetrically ^ infundibuliform, 
subspathaceous, entire, truncate and naked at the mouth; finely striately veined, pro- 
duced at one side into a rather acute tip; involucre dimidiately cupular or shaped like 
a swallow's nest, anticously truncate, posticously deeply lunately emarginate, acutely 
two-keeled and bi-dentate next to the axis. Male flowers narrowly ovate, obtuse, 
slightly curved or asymmetric; the calyx striately-veined, with 3 broad lobes; the 
corolla one-third longer than the calyx—its segments polished externally, apiculate or 
almost obtuse. Female spadiz elongate with rather many remote (about 40 cm. apart) 
partial inflorescences; primary spathes as in the male spadix, the lowest about 25 em. 
long, split longitudinally on the ventral side and acutely bicarinate on the back, the 
carin; armed with small remote ascendent spines; axial portions of the spadix 
(between two partial inflorescences) concave on the inuer side at their base and 
convex and sparingly clawed dorsally; partial inflorescences very elongate, 30-50 cm. 
long, terminated by a short, filiform, unarmed, tail-like appendix, the largest with 12 
spikelets on each side; secondary spathes elongate-infundibuliform, unarmed and 
almost polished, truncate at the mouth and extended on one side into a broadly 
triangular and rather acuminate point; spikelets inserted a little inside the mouth of 
their respective spathes, rather thick, arched and recurved, the largest, the lowest, 
10-20 cm. long with 10-18 flowers on each side, the upper ones gradually decreasing 
in length and number of flowers, the uppermost half the length of the lower ones; 
spathels infundibuliform, unarmed, indistinctly striately veined, truncate and entire at 
the mouth and prolonged at one side into a short triangular ultimately withered 
spreading point; involucrophorum inserted at the bottom of its own  spathel, 
subspathaceous or obliquely cupular, acutely bicarinate, bi-dentate and emarginate on 
the side next to the axis, almost entirely enclosed in its own spathel; involucre 
unilaterally cupular, rather deep, my with the areola of the sterile flower ovate, 
sharply defined, Female flowers about 5 mm, long, ovate. Fruiting pertanth not
