edge only; on the under surface it is smooth a long way up, but shortly below 
the cirrus it is armed with ternate claws; the cirrus is rather slender, about 
l m. long, with a few reduced and scattered leaflets along its lower portion, 
otherwise powerfully armed at almost regular distances of 15-20 mm. with 
half-whorls of not very robust but very sharp claws. Leuflets not very numerous, 
about 50 on the whole, very inequidistant, usually very conspicuously approximate 
in pairs on each side of the rachis, occasionally with solitary ones between the 
pairs (vacant spaces between the pairs 6-10 cm. long): the two of each pair 
very approximate (1-3 cm. apart); leaflets lanceolate-elliptical, tapering equally 
from their middle downwards to an acute base and upwards to a gracually very 
acuminate quite glabrous and smooth tip, they are thinly pupyraceous, deep green, 
and almost equally shiny on both surfaces, quite devoid of hairs or spinules in 
every part, including the margins and the apex, and only at times furnished 
with a solitary, erect and relatively robust spinule on the mid-costa near the base: 
they are faintly 5 costulate, all the  costulae being very slender: the central 
is slightly stronger than the side ones, which are scarcely more prominent than a 
few secondary nerves interposed between them; transverse veinlets slender but very 
distinct, pellucid, rather numerous, very sinuous ; the intermediate leaflets are 18-25 cm. 
Jong, 3-4 em. broad, those of both ends much reduced. Male spadiz rises erect 
some centimetres below the mouth of the leaf-sheaths, is ultra-decompound with several 
partial inflorescences; it forms a very lax, diffuse and recurved partial inflorescence 
1-1:50 m. long on the whole. The lowest primary spathe is about 15 em. long: 
it. sheaths the entire peduncular part of the spadix, and carries just at its 
mouth a partial inflorescence like the upper spathes: it is strongly flattened, 
acutely two-edged, 15 mm. broad in its upper part, slightly narrowing towards the 
base, obliquely truncate at the mouth and produced at one side into a rather 
elongate point: it is prickly only at the end of its dorsal keel; upper primary spathes 
closely sheathing, more cylindraceous and shorter than the lower, also prolonged into 
an elongate acuminate point which is acutely keeled on its back and provided 
with a few spinules, otherwise the entire surface of all the spathes is smooth; 
partial inflorescences inserted just at the mouths of their respective spathes; the 
lowest about 60 em. long with 3-4 spreading branches on each side in its lower 
part and several simple spikelets from the middle upwards; upper primary  inflorea- 
cences reduced in length and number of secondary branches; secondary  spathes 
tubular, slightly enlarged above, closely sheathing, smooth, very obliquely trun- 
cate and ciliate at the mouth, produced at one side into a broadly triangular acute 
point; they are usually shorter than the space interposed between two branches, 
or in other words the branches (and the spikelets also) are inserted somewhat above 
the mouth of their respective spathes; lower branches 15-18 cm. long with about 
12 spikelets, very regularly and distichally set on each side; the lower spikelets of 
the branches are about 3 cm. long, somewhat arched, when loaded with flowers 
flattened and pectinate, about 7 mm. broad, and with 15-18 very approximate 
or contiguous flowers on each side, and spathels extremely approximate, concave, 
bracteiform, horizontal or somewhat deflexed, but subtending the base of their 
respective flowers with their acute ascendent points; involucre sub-dimidiately cupular, 
more or less distinctly bidentate on'the posticous side; both spathes and involucre 
are minutely ciliate on the edges; the spikelets of the terminal part of the partial
