the lower elongate axial parts, rigid and erect in its lowest portion, nodding in 
the upper, with 4-5 much spaced, gradually diminishing primary or compound partial 
inflorescences and with a very slender, almost capillary, unarmed appendage; at its 
upper end the lowest compound partial inflorescence is about 50 cm. long and bears 
about 10—12 gradually diminishing spreading secondary or spikelet bearing branchlets 
on each side; the upper secondary branches are gradually shorter and with fewer 
spikelets, and those towards the end are reduced to simple spikelets, but more 
elongate than usual; primary spathes strongly flattened, very narrow, subcoriaceous, 
rigid, split and open on one side almost to the base, dotted with small rusty 
scales; secondary spathes narrowly tubular infundibuliform, truncate and deciduously 
ciliolate-paleaceous at the mouth, produced at one side into a short triangular 
acute point; the spikelet-bearing branchlets are inserted just at the mouth of their 
respective spathes, and have a distinct axillary callus with transverse rima: the lowest 
is 10-15 cm. long and bears on each side 12-18 spreading, gradually diminishing 
spikelets and is tail-like with simply  bifarious flowers at its end; tertiary spathes 
short and loosely infundibuliform; the spikelets of the lower part of the branchlets 
of the lower partial inflorescences are 12-15 mm. long and have 8-10 flowers on 
each side; those of the upper part of the largest inflorescences and those of the 
‘inflorescences towards the ead of the spadix are 2-3 times as long and proportionally 
with more flowers; spathels very closely packed, braeteiform, concave, horizontal 
or slightly deflexed, strongly striately veined, ciliolate, their points acute and 
longer than their respective involucre which is dimidiately cupular, bidentate on the 
side next to the axis ard striately veined. Male flowers horizontal and in contact 
with one another causing the spikelets to assume a pectinate appearance, very 
narrow, terete acute, 5-5: mm. long, 1-5 mm. thick; the calyx tubular, briefly 
3-toothed,  striately veined; the corolla polished, twice as long as the calyx.

of about 6 gradually diminishing partial inflorescences; primary  spathes rigid-

thence into an auriculiform, lanceolate, acuminate, entire limb; they are tubular in their 
lower part, which gradually narrows and pass into the slender but rigid, strongly
