Description.— Scandent, rather robust. Sheathed stem 45-5 cm. in diameter 
Leaf-sheaths strongly gibbous above, dull green and quite smooth on their surface 
and at the mouth; ocrea obsolete. Leaves large, about 2 m. long in the pinni- 
ferous part; petiole short and robust, about 3 em. broad at its strongly  flattened 
base, flattisa above, coavex underneath, armed with very small prickles near 
the bluntish edges only, otherwise smooth; the rachis, in its first portion, is also 
flattish above and convex below and equally smooth, and has narrow flattish edges, 
where the lowermost leaflets are inserted: higher up it is convex above or with the 
salient angle obtuse and never sharp, even towards the end: underneath, in the 
upper portion, it is armed with robust claws, at first solitary, then confluent in groups. 
of 3-5 and 5-8; the cirrus is very robust, about 1:5 m. long and very power- 
fully clawed. Leaflets numerous, sub-equidistant, 6-10 cm. apart on each side, 
2longate-lanceolate, equally and gradually taperiog towards an acute base and an 
acuminate, slightly bristly tip, firmly papyraceous, sublucid, equally green and quite 
glabrous on both surfaces; the mid-costa very slender and somewhat stronger than 
2-3 other costulae, which are only a little more conspicuous than the secondary 
nerves interposed between them; transverse veinlets very numerous, sharp and 
continuous; margins remotely, very minutely and appressedly spinulous; the inter, 
mediate leaflets about 40-50 cm. long and 4-5 cm. broad. Male spadiz large and 
diffuse, apparently ultra-decompound, with several partial inflorescences, which carry 
humerous secondary branches, of which the, spathes are 4 cm, long, tubular, slightly 
infundibuliform, smooth, obliquely truncate and ciliate with fine paleolae at their 
mouths, and produced at one side into a triangular acute point; -the spikelet-bearing 
branches are inserted just at the mouths of their respective spathes: those seen 
by me are 25-28 cm. long, and carry distichally with great regularity 14 spikelets 
on each side; the spathes of the branches are narrowly infundibuliform, 10-12 mm. 
long, sprinkled with very small adherent thin scales, and are truncate and ciliate 
with fine paleolae at their mouths; spikelets inserted just at the mouth of their res- 
pective spathes, archad, when loaded with flowers flattened, pectinate and abuut 
8 mm. broad, when the flowers have fallen acutely tetragonous and about 3 mm. 
thick; spathels extremely approximate, concave, bracteiform, horizontal or somewhat 
deflexed, but subtending the bases of their respective flowers with their acute ascen- 
dent points ; the involucre is dimidiately cupular or like a swallows nest; the 
spathes and involucra are scaly furfuraceous externally and more or less minutely 
ciliate on the edges. Male flowers almost horizontally inserted, ovoid, acute, 
3 mm. long. Female spadix simply  decompoupd, inserted a few centimetres 
above a leaf azil, about 1:5 m, long on the whole; it forms a diffuse
