p dily decreasing in length; the two of the terminal pa,r 8-1» cm. long, free at

partial inflorescences and a terminal filiform appendix which is aculeolate all round;

inflorescences flattened on the inner side, convex and strongly armed on the back
with solitary ot more or less aggregate claws; partial inflorescences not numerous,
iemote, inserted not very far inside the mouth of their own spathe and arising
erect from this; the largest, the lowest, 20-30 em. long, forming a rather dense
compound panicle, which bears few branchlets or compound spikes m its lower
portion and many simple apikelets in the upper part, the latter decreasing in
length from the base towards the summit; the upper inflorescences gradually
•smaller, the extreme only 6-8 cm. in length, undivided, and with 4-10 distichous
each side; secondary spatlies very narrowly tubular-infundibulilorm,
mgular. gradually decreasing in length from the base to the top of the
panicle, more or less obliquely truncate, decidnonsly ciliolate at the month and
p r o l o n ^ d at one side into a short, triangular, subulately acuminate often withered
point; Ispikelets inserted at the mouth of their own spathe, callous at their upper
aiilla, the largest (the lowest of each branchlet) 2-3-5 cm long, with 10-15 up to
20 flowers on each side, complanate, straight at flrst, arched or subscorpioid after
•the fall of the flowers; the uppermost not more than 1 cm. long ; spathels very
•closely packed, bracteiform, concave, very broad, embracing the flowers, horizontal
or slightly deflexed, striately veined eiteinally, often ciliolate, acute or apiculate at
one side; involucre included in its own spathel and laterally attached at the
base of the one above, dimidiately cupular or like a swallow's nest, truncate,
deeply Innately emarginate and acutely two-keeled and bidentate on the side next
-to the axis. Male fiowm perfectly bifarious, very crowded, the one in contact with
the next, inserted at a rather open angle, ovate, small, 2-5-3 mm. long, obtuse or
sub-apiculate; the calyx sub-campanulate, faintly striately veined externally, divided
down almost to the middle into three large acute lobes, with pale subscarious
margins; the coroHa twice as long as the calyx, divided down to its lower third
part into three ovate, acute and externally polished segments; the filaments of the
stamens rather stem and rigid, subulate with infiected apices when in the bud and
united |by their bases into a fleshy body as long as the undivided part of the
corolla; the anthers versatile, lancoolate and acute, their cells discrete at the base;
the rudimentary ovary formed by three subulate rigid bodies united by their bases
•and inserted in the fleshy infundibuliform disc formed by the base of the anthers.
FetitaU sfaiiz simply decompound, flagelliform like the male, but perhaps smaller,
about 70 cm. long, including a not very long aculeolate apical flagclluni; lowest
primary spathe tubular, somewhat flattened, acutely two-edged, very sparingly
spinulous; the upper spathes cylindraceous, often split on the ventral side at the
summit; partial inflorescences few, the lowest, the largest, 15-20 cm. long with a
straight rigid axis, and with 8-9 distichous spikelets on each side; secondary
suathcs as in the male spadix; spikelets arched, patent or slightly deflexed, more
or less dietinctly callous in their upper axilla; the lowest, the largest, 2-5-4 cm.
long, -with 12-18 distichous very crowded flowers on each side; the upper ones
.gradually shorter and more approximate; spathels very closely packed, bracteiform, a
little larger than but of the same shape as in the male spikelets; involucrophorum
embraced by its own spathel and attached at the base of the one above, with a
short concave unilaterally evolute limb; involucre concave, unilaterally evolute, subauriculiform,
obtuse; areola of the neuter flower nearly round, sharply defined by
