28 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. (C. filispadix. 
times longer, and with more numerous flowers : the leaflets have no bristles on 
the mid-costa on the lower surface; but, as I have already said, Meebold’s speci- 
men has only a radical leaf, and it is not therefore exactly comparable with 
those of the type specimen. 
Wright’s specimen from Courtallum (in Kew Herbarium) has spherical fruits, 8 
mm. in diameter, surmounted by a cylindrieal beak ; the seed is erbicular, 5 mm. 
in diameter, coarsely pitted, and with a deep chalazal fovea in the centre of the 
raphal side.

Descrrption.—Slender. Sheathed stem about 2-2°5 cm. in diameter. Naked canes 
13-14 cm. in diameter with a straw coloured polished surface and internodes 14 em. 
long. Leafsheaths strongly gibbous above, densely armed with very uneqnal spines, 
of which some are lerge, arranged in horizontal approximate rows, and confluent 
by their bases, laminar, lanceolate or elongate-triangular, 12-20 mm. long and at 
times longer, dark brown with a lighter, slightly swollen, 6-7 mm. broad base; 
the spaces between the rows of large spines are covered with similar spines but 
much smaller, very unequal, and scattered or slightly confluent; the mouth of the 
sheath is edged by a narrow membranous rim, representing the  ocrea. Leaves 
elongate (non cirriferous’, about 15 m. long (in one specimen) in the 
pinniferous part; petivle about -25 cm. long, concave on the upper surface near 
the base, flattish higher up and more or less prickly throughout; the lower 
surface is convex with a line of small claws along the centre and with the edges 
acute and armed with several rather large horizontal spines; the first portion 
of the rachis is convex and irregularly armed on the lower surface with several 
robust claws; on the upper it has a deep furrow on both sides for the insertion 
of the leaflets and a narrow, flat, and at times slightly prickly surface; along the 
centre, higher up, the rachis is more regularly armed with 2-3-nate claws under- 
neath and on the upper surface has a very sharp salient angle smooth or minutely 
and sparingly prickly. /caflets numerous, equidistant, rather closely set, 25—35 
cm. apart on each side of the rachis, regularly alternate, papyraceous, rigidulous, 
almcst of the same colour on both surfaces, linear-ensiform, tapering lower down 
towards a rather acute base, gradually acuminate towards the apex from below 
the middle, sharply 3-eostulate; the 3 costs are very sharp and sparingly bristly 
only from above the middle on the upper surface, and on the lower are slender 
and closely covered with short fulvous bristles; the margins, especially the lower, - 
are slightly thickened and very minutely and inconspicuously spinulous ; transverse, 
veinlets fine and rather numerous; the intermediate leaflets (largest) are 50 cm, 
long, 18-20 mm. broad, and have a very acuminate and bristly apex; those 
near the base are narrower but not shorter; the upper ones gradually shorter;
