Descripiion.—Scandent, rather slender, Sheathed stem 13-14 mm, in diam.  Leaf- 
sheaths rusty-brown furfuraceous, not or very slightly gibbous above, very un- 
equally and irregularly armed, especially on their lower and dorsal part, with rather 
large, very thinly laminar, deflexed, scattered spines, and with several short series 
of very small, crinitorm, black, ascendent spiculae; near their mouths and also 
at the base of the petiole, on the anticous aspect, the spines grow thicker and 
longer, and more slender, sometimes criniform, point in opposite directions, up and 
down, and are united by their bases so as to form a few membranous crests, 
which occasionally give shelter to colonies of ants Leaves elongate, about 1 im. 
long in the pinniferous part, and terminating iu a slender clawed cirrus; petiole 
about 25 cm. long, glabrous, polished, plano-convex near the base, slightly bieonvex 
in its upper part, the edges acute, and armed near the base on the upper surface 
with long (up to 4-5 cm.) very thinly laminar, narrow, subulate, straight, rather 
densely set spines, and on the intermediate portion with short prickles, the 
uppermost portion being unarmed; underneath, the petiole is smooth, or has 
only a few prickles near the base where it is armed with a line of long straight 
approximate spines and small remote claws higher up; the rachis in its lower 
portion is convex above, and has a narrow and deep groove on each side for the 
insertion of the leaflets; in the intermediate portion it is armed underneath, 
along the centre, with small solitary claws, which become ternate only towards 
the upper end and on the cirrus; on the upper surface the rachis is smooth and 
has an acute salient angle and flat side-faces; leaflets numerous, equidistant, 
2-3 cm. apart, broadly linear-lanceclate or linear-ensiform, 27-28 cm. long, and 
12-15 mm. in width, broadest about the middle, and thence tapering almost equally 
towards both ends, or gradually acuminate to a filamentous and bristly tip, and to 
an acute base, green on both surfaces, but paler beneath; on the upper surface 
the mid-costa is very slender and glabrous, slightly decurrent at its base along the 
salient angle of the rachis; there is also one slender secondary nerve on each 
side of the mid-costa which is occasionally furnished with a few black bristles, 
but otherwise is quite smooth; underneath, the leaflets are densely bristly- 
spinulous on 5 nerves, but more closely on the mid-costa; transverse  veinlets 
numerous, translucent and sharp on both surfaces; margins not very appressedly yet 
closely ciliate-spinulous. Male spadiz before flowering erect, slender, cylindraceous, 
as thick as a man's little finger, acuminate; primary spathes about 6, thirly 
papyraceous, exsuccous, brown and dull on both surfaces, all quite unarmed, glab- 
rous, finely striately veined externally, linear-lanceolate, acuminate, tubular before 
the anthesis, but soon split longitudinally on the ventral side; the outermost rather 
acutely two-keeled, 25 cm. long; the inner spathes do not protrude much beyond 
each other and are acutely keeled at the apex; the flowering panicle is strict, 
cupressiform, has about six partial inflorescences, is about 40 cm. long and is 
supported by a flattened peduncular part about 20 cm. long, 7-9 mm. broad, with 
very acute edges that bear a few flabby spiculae; the partial inflorescences are
