DESCRIPTION.—Very slender, scaadeat. Sheathf-d stem 6-7 cm. in diam. Leafsheaths
not cirriferous, covered like the spadix and Icaf-rachis -vvitli a rusty-furfuraceous
removable indumentum, longitudinally striate, gibbous above, obliquely truncate at the
mouth, irregularly armed with slender, flat, subulate, unequal, scattered, dark, straight,
slightly deflexed, 10-12 mm. long spines, with which are intermingled other very
small, and sometimes sub-tuborouliform spinules. Ocrea very short, roduced to a short
axillary iigule and to a narrow scabridous margin at the mouth of the sheath. Leaves
delicate, cirriferous, 35-50 cm. long in the pinniferoua part; tiie cirrus slender,
filiform, elongate, armed with solitary or more or less aggregate slender claws; petiole
short or very short ( 1 - 3 cm. l o n g ) , flat above, where sometimes spinulous as on the
first portion of the rachia, convex beneath, where armed with a few long and straight
spines which upwards on the rachis are transformed into scattered unequal and sometimes
very small claws; in it« upper part the rachis is bifaced and smooth; leaflets
not numerous ( 1 4 - 1 6 in all ) inserted at an angle of 40®, distinctly approximate in
distant pairs on each side, the pairs sub-op posits and therefore forming 4 very
•distincifc groups of 4, separated by a long ( 8 - 1 0 cm.) vacant space; thinly papyraceous,
rather rigid, somewhat plicate, chiefly at the base, otherwise explanate, green
even when dry, subconcolorous, slightly paler beneath, oblanceolate, gradually narrowed
and acute at the base, rather suddenly acuminate at the summit into a slender
tip, this bristly spinulous at the margins, with 3-5 slender costs which are almost
equally prominent and naked on both surfaces and with 1-2 rather distinct secondary
nerves between the main cost»; transverse veinlets v e i y distinct, rather crowded;
margins finely spinulous, the largest leaflets, the intermediate ones, 15-19 cm. long,
2 - 3 cm. broad, the uppermost and especially the lowest conaiderably smaller.
Male spadix Female spadix very elongate, slender, subflagelliform, simply
decompound, with many small remote partial inflorescences; lowest primary spathe
; upper primary spathes tubular, cylindraceous, very elongate, (ilosely
eheathing, obliquely truncate at the mouth, where prolonged at one side into a short
erect point, suddenly narrowed at the base into the very slender filiform flattened
obsoletely angular axial part, rather densely armed with very small deflexed prickles,
which have a light swollen base and a brown tip or are tuberculiform or slender and
subulate and oven 1 cm. long; partial Inflorescences 15-20 cm. apart, inserted at the
mouth of their respective spathe with a distinct axillary callus, spreading, small, the
largest 10-12 cm. long with 9-10 spikelots on cach side; secondary spathes short,
tubular-infundibulifonn, more or loss angular, somewhat loosely sheathing, entire,
truncate and subscarious at the mouth, barely apiculate at one side, unarmed and
finely longitudinally striate; spikelets inserted above the mouth of their respective
spathes witb a distinct axillary callus, recurved and subscorpioidly arched, the lower
ones, the largest, 2 ' 5 - 3 cm. long with 10-12 pairs of flowers; epathels narrow and
more or less angular at the base, suddenly expanded above into a short broadly
infundibuliform entire limb, which is prolonged at one side into a short usually
deflexed point; involucrophorum laterally attached outside its OWQ spathel at the
base of the one above, sessile or with a short neck, suborbicular, discoid with a

narrow and unequal margin; involucre also discoid, flat, orbicular; areola of the
neuter flower callous-spongy. Female flowers in two series not disposed distinctly on
one plane, but slightly turned upward, oblong, about 3 mm. in length; the calyx
tubular, slightly inflated in the middle, finely striately veined, with 3 very short
triangular acute teeth; segments of the corolla narrower and almost shorter than
those of the calyx. Neuter flowers as long as but narrower than the female ones,
with the calyx short, 3-gonous, acutely S-dentate and the corolla a good deal longer
than the calyx; the segments valvate and finely externally striate. Fruiiing perianth
distinctly pedicelliform. Fruit small, ovoid, distinctly suddenly mucronate, about 1
cm. long (including the mucro) and 6 mm. broad; scales in 17-18 series, reddish
brown, slightly convex, not or slightly channelled along the middle, subshining
s l i g h t l y prolonged into an obtuse point, with a relatively large dark intramarginal
l i n e ; margins erosely toothed. Seed ovoid, about 6 mm. long, coarsely and irregularly
pitted and grooved ; the chalazal fovea narrow, in the centre of the raphal
s i d e ; albumen equable, except for the superficial intrusions of the crustaceous integument
; embryo basal.
