DesckipTion,—Scandent, of moderate size. Sheathed stem 3 em. in diam. Leaf- 
sheaths flagelliferous, gibbous above, more or less covered with a greyish-brown scurf, 
especially abundant in the younger parts, including the spines; densely armed with 
solitary or approximate and even subseriate flat subulate sublanceolate straight deflexed 
or slightly hooked spines, which are intermingled with others smaller and very 
slender, also scattered or subseriate; the largest spines are 10-15 mm. long, their base 
is broad, swollen above and concave beneath, Ocrea very short, coriaceous, truncate, 
Leaj-sheath flagella compressed in their lower portion, where armed with straight 
slender spines on the edges. Leaves rather large, not cirriferrous ; petiole green, even 
when dry, about 25 cm. long; rather stout, almost equally convex on both surfaces, 
but more undernesth where armed along the middle with Spines similar to those of 
the spathes, but gradually transformed into claws upwards; margins rather acute and 
furnished with unequal spines, solitary or grouped, straight and ascendent or deflexed ; 
rachis acutely bifaced above from near its base, armed below along the middle with 
a single series of solitary claws; leaflets numerous, equidistant, usually Opposite especi- 
ally towards the summit, narrowly ensiform, somewhat attenuaie at the base, very 
long-acuminate into a bristly penicillate tip, subshining on both surfaces, slightly 
paler beneath, where quite naked or with a few long bristles scattered along the 
mid-costa, distinctly 3-carinate above, where the mid-costa is very acute and much 
more prominent than the side-nerves; these usually more than the central one 
sprinkled with long or short bristles or more rarely naked; margins acute, very 
distinctly  ciliolate-spinulous; transverse veinlets indistinct; the largest leaflets, up to 
70 cm. long but usually 40-50 em. and 2:5-3 em. wide; the upper ones smaller; 
the two of the terminal pair less acuminate than the others, 12-15 cm, long, quite 
free at the base. Male spadix . . . . . Female spadiz very elongate, terminating 
in a very strong and excessively long flagellum (3 m., 6rififh) which is powerfully 
armed with strong broad-based solitary or variously confluent half-whorled or some- 
. times nearly completely whorled claws; the axis of the spadix straight, rigid, robust, 
bearing a few very distant partial inflorescences; lower primary spathes somewhat 
compressed and two-keeled, more or less armed with straight, short, solitary, more or 
less horizontal, broad-based spines; upper primary spathes very elongate, some of them
