Description.—Seandent, very slender. Sheathed stem 6 mm. in diam,  Leaf- 
sheaths light yellowish like the other parts of the plant when dry, flagelliferous, 
gibbous above, sprinkled with small rusty seales, armed with very small short ascendent 
black-tipped prickles which rest on a broad and tumescent base and are flat 
underneath. (crea short, thinly coriaceous, obliquely truncate, naked. Leas-sheath 
flagella slender, callous at their insertion, armed from the base with at first 
scattered and upwards half-whorled claws. Leaves impari- or sub-imparipinnate, or 
subcirriferous and terminating in a rudimentary leaflet, small, 35-40 cm. long, 
epetiolate ; rachis more or less obsoletely trigonous, rather densely and irregularly 
armed thoughout to the base of the terminal leaflet with rather robust black- 
tipped solitary or even geminate and ternate claws ; leaflets very few, about 10 in 
all, remote, very inequidistant, but not with a tendency to be approximate in 
groups, narrowly elliptic-lanceolate or oblanceolate, gradually tapering lower down 
towards a very acute base, usually broader above the middle, and thence rather 
suddenly narrowed to a subulate tip, which terminates in a emall brush of a few 
black bristles, firmly but thinly papyraceous; opaque and yellowish-green on both 
surfaces (when dry), sub-5-costulate ; the mid-costa slender acute, the side costae 
still more slender and often indistinguishable from other secondary nerves, two 
of which almost marginant, all naked on both surfaces; transverse veinlets very 
sharp and distinct on both surfaces, very close together and continuous across the 
blade; margins quite smooth; the largest leaflets, the intermediate, 14-15 cm, 
long, 18-20 mm. broad; the two of the lowermost pair horizontal, smaller, 
inserted just at the mouth of the sheath, the upper ones somewhat smaller, the 
one at the summit the smallest; often the leaf terminates in two unequal leaflets, 
the one decurrent on the other. Male spadix very slender; longer than its leaf, 
with 3-4 remote partial inflorescences and terminating in a filiform aculeolate 
flagellum ; primary spathes tubular, very narrow, very closely sheathing, rather 
densely and sparsely clawed, obliquely truncate and naked at the mouth where 
prolonged at one side into a short triangular point, their base gradually passing 
into a slender elongate, externally clawed, axial part; partial inflorescences lax, 
elongate, inserted with a conspicuous arillary callus above the mouth of their 
respective spathes; the largest, the lowest, 15 cm. long, with 4-5 spikelets on each 
side; secondary spathes smooth, excessively narrow, very closely sheathing, ered 
een above, or  sübelavate, truncate and apiculate at one side the 
mouth ; spikelets horizontally inserted outside the mouth of their own spathe pA a 
distinct axillary callus, their axis very slender, slightly sinuous between the flowers;
