! Description.—Rather slender, high scandent. Sheathed stem 13-18 mm. in diam. 
Leaf-sheaths (non-flagelliferous) very obliquely truncate at the mouth, strongly gibbous 
above, the youngest marbled with green and white-mealy patches and more or less 
furfuraceous, the adult ones yellowish green (when dry) more or less distinctly longi- 
tudinally striate, armed with strong scattered, solitary, straight subulate, horizontal or 
slightly deflexed, slightly curved or almost claw-shaped large spines, 1-2 cm, long 
‘which have a base extraordinarily broad, callous, swollen above and concave beneath; 
sometimes with the larger spines near the summit of the sheath are intermingled 
others smaller, tuberculiform and ascendant; in youth all are cottony-furfuraceous 
at the margins, Ocrea very short, reduced to a small obtuse ligula and to a 
narrow naked rim at the moutn of the sheath. Leaves cirriferous, the pinniferóus 
part 60-80 em. long; petiole very short or almost wanting; rachis smooth above, 
where flat near the base but speedily acutely bifaced, slightly convex underneath, 
where in its lower portion armed along the middle and at the sides with 
solitary scattered light-based  black-tipped claws; these are 3-nate and higher 
up half-whorled, the half-whorls very regularly set at gradually shorter intervals 
on’ the cirrus; the cirrus itself about 1 metre in length; leaflets few, 16-24 
i all, very irregularly set, usually approximate in pairs on each side, the 
pairs 15-20 cm. apart, those of one side usually alternating with those of the 
other side or sometimes sub-opposite, more or less concavo-convex, oblong-lanceolate, 
gradually - tapering towards the base, which is acute, acuminate into a short 
‘spinulous apex, papyraceous, rigidulous, conspicuously discolorous (chiefly in recently 
expanded leaves), sub-shining, green and glabrous above, conspicuously mealy-glaucous 
beneath, acutely 4—5-eostulate with some other distinct secondary nerves interposed, 
all naked on both surfaces and very faint beneath; transverse veinlets very fine, very 
numerous and approximate on the upper surface, obliterate beneath; margins minutely 
and closely spinulous upwards, more remotely near the base; the lower margin 
bordered on the upper surface with a distinct shining stripe, similar stripes occurring 
also on the blade, chiefly near its summit; the largest leaflets, those of the middle, 
30-35 em. long, 5-6 cm. broad; the lower ones much narrower and more 
distinctly callous at their insertion; the upper ones saree but not much narrower.— 
Other parts unknown. 
Hasitat.—South Borneo, according to Blume, where the sterile specimens upon 
which the species was founded were collected by Henrici. 
I have referred to this species one specimen ( also sterile) collected by Scortechini - 
in the district of Perak in the Malayan Peninsula (No. 456 in Herb. Becc.), where
