Description.—Scandent, slender. Shevthed stem 1-2 cm. in diam. Leaf-sheaths 
flagelliferous when not spadicigerous, gibbous above, densely bristly at the mouth, 
furfuraceous when young, more or less armed with straight slender spines which 
leave rather deep impressions on the surface of the sheath. Ocrea very short, 
spinulous. Leaves not cirriferous, broadly ovate in outline, rather short, 40-70 cm, 
long; petiole rather short, flat above and very sparingly spinulous; rachis fugaciously 
furfuraceous, acutely bifaced and smooth above, flattish beneath where armed with 
solitary black-tipped claws; leaflets subequidistant and not very regularly alternate in 
the upper part of the leaf; usually inequidistant but not distinctly grouped nearer 
the base, narrowly lanceolate or linear-lanceolate, gradually acuminate into a bristly 
tip; attenuate at the base, glabrous, thinly chartaceous, not shining above, almost of 
the same colour on both surfaces, the mid-costa very acute and  spinulous above, 
where accompanied by 3-4 rather weak, usually naked secondary nerves, of which 
sometimes one on each side of the mid-costa is sparsely spinulous and somewhat 
stronger than the others, in this case (the leaflets) faintly 3-costulate; beneath the 
mid-costa not prominent, but also bristly-spinulous as, very sparingly, is often one 
of the secondary weak nerves on each side of it; transverse veinlets distinct, much 
interrupted and not very crowded; margins very slightly thickened by a very 
slender nerve and rather strongly spreadingly spinulous-serrulate; the largest leaflets, 
those a little above the base 20-40 cm. long, 22-25 mm. broad, the others rather 
speedily decreasing in length; the two of the terminal pair 8-15 em. long, free at 
the base. Male spadix elongate, flagelliform, ultradecompound, with not many distant 
partial inflorescences and a terminal filiform appendix which is aculeolate all round; 
primary spathes very long, the lowest flattened; the upper ones tubular, very 
closely sheathing, thinly coriaceous and armed with many small recurved aculei, 
often more or less withered at the apex and furnished, when young, at the mouth 
with many paleaceous bristles; the axial unsheathed portions between two partial
