size, light-coloured with a brownish tip, horizontal, subulate 8-15. mm, long,  Ocréa 
very short, liguliform and forming a narrow rim to the mouth of the sheath. - Leaves 
elongate in outline, about 1 metre long in the pinniferous part, terminating in a 
slender cirrus, this armed with approximate half-whorls of small _ black-tipped claws; 
petiole obsolete; rachis in the upper surface flattish near ‘the base, ` ` angular 
upwards and more or less armed throughout with unequal and rather robust prickles ; 
in the lower surface clawed along the middle; leaflets numerous, very ` distinctly 
approximate in many fascicles, each of these 3-7 cm. apart ind forméd on each 
side by 3-9 very approximate leaflets, the fascicles of one side often sub-opposite 1o 
those of the other side; furthermore the leaflets are thin in texture, subherbaceous, 
green and concolorous on both surfaces, linear, narrowed towards the base, gradually 
acuminate at the summit into a finely subulate tip, 20-25 em, long, about 1 cm. 
broad with the mid-costa acute above, and this often accompanied there on each 
side by another secondary | nerve and thence sub-3- costulate, all nerves naked on both 
surfaces; transverse veinlets remote, much interrupted, ` inconspicuous ; margins very 
indistinctly and adpressedly spinulous; the upper leaflets gradually decreasing in size, 
less, distinctly grouped and irregularly set. Male spadiz ... ... .. Female spadiz 
inserted about midway on its sheath, 1 m. long with 6 partial inflorescences in one 
specimen. and terminating in a slender filiform tail-like appendix; ultradecompound, 
much branched, panicled, loose, quite unarmed in every. part; lowest primary spathe 
tubular, elongate, very closely sheathing, flattened,. acutely two-edged; upper spathes 
more cylindraceous, closely sheathing, rather thin in texture, narrowed at the base 
into the flattened axial part, prolonged at the summit into a rather elongate acumi- 
nate point; partial inflorescences inserted at the mouth of their own spathes, diffusely 
panicled: pyramidate, the lower ones the largest 30 cm. long with 6-7 gradually 
diminishing branchlets on each side, besides a few simple spikelets in the terminal 
parts, the lower branchlets 10-12 mm. long, pyramidal in outline, with 8-9 gradually 
diminishing spikelets on each side ; secondary spatues very small, tubular-infundibuli- 
form, scarious in their upper part, truacate and entire at the mouth and. prolonged 
.at one side into an erect triangular point; spikelets horizontally inserted above the 
mouth of their respective spathes, slightly arched, very slender, the larger ones, the 
lowest of each branchlet 4-5 cm. long, with 5-7 flowers on each side; spathes closely 
sheathing, tubular, slightly enlarged and exsuccous or subscarious in their upper part; 
involucre laterally attached at the base of the spathel above its own and quite 
exsert from this, cupular; . involucre exactly cupular, entire; areola of the neuter 
flower lunate. Female flowers very small, 2*5 wm. long; the calyx with 3 broadly 
triangular lobes; the segments of the corolla barely narrower than the teeth of 
calyx and about as long. Fruiting períanth distinctly — pedicelliform with a flat 
base. Fruit very small when very young globular shortly beaked; scales in 15 
longitudinal series, straw-yellow coloured with a red-brown marginal line, not 
channelled along the middle.
