Desckiption.—Scandent, of moderate size. Sheathed stsm 22-30 era. in diam. (in
cue specimen). Loaf-sheaths gibbous above, coriaceous and almost woody, rusty-fuvfuraceous,
strongly striata longituiHnally, the mouth obliquely truncate, and armed
with a number ot large, erect, straight, thinly laminar, elastic, 7 - 8 cm. long spines;
otherwise the entire surface, and the base of the petiole above the g-ibboaity ia
armed with numerous, rather large (2-3 cm long, 3-5 mm. broad), thinly laminar,
brown-schistaceons, spreading or dcflesed, usually solitary and scattered spines which
when young have fringed furfuraceous edges ;uid are set in a hao along the ventral
side; near the mouth the spinos are smaller, but very crowded and ascendent.
Ocrea inconspicuous. Leaves 1'5 m. loQg in the pinuiferous part an I terminatinii in
a slender, elongate cirrus; petiole elongata (51) cm. in ooe specimen), biconvex with
the edges very obtuse, escept at the base, \vhere tuey are rathe.- acate, and
armed with a few, straight, and long spines, otherwise the edges espjcially
on the upper surface, are armed with very small, short and straight, sohtary
or more or less aggregated prickles; underneath, the petiole has a few
straight spines at its base along its centre, otherwisa it is smooth bat
for some small, solitary prickles which appear only where the leaflets begin ;
the rachis is convex above in it? first portion, then, bit'acei, with a very
acute salient angle, smooth throughout ; unierneath the claws, at first solitary,
become as usual 3-nate and -5-nate upwards, and half-whorled oti the cirrus ;
leaflets numerous, equidistant, 2-3 cm. apart oa each side, papyraceous, green,
dull, paler beneath, linear-lanceoUto, broadest about the middle or a Utile below,
and thence gradually narrowing towards the base, and upwards into a finely
subulate and filamentous tip; they are distinctly 3-costaIate on the upper
surface where the mid-costa is slightly stronger thaa the 2 side nerves and all 3
or the middle one only hristly-spinulous from the middle upwards; on the undersurface
5 - 7 nerves are very closely covered wif.h very small bristly spiimles ; transverse
veinlets very distinct, rather ituinerous, much interrupted; margiiis minutely
and very appressedly spiiiulous, tüc lower margin on the upper surface bordered
by a very narrow shining band. íÁpndices before flowering erect, cylindraceous, as
t h i ck as a man's finger; primary spathes thickly coriaceous, almost woody, at
first tubular or narrowly ear-shaped, each projecting a good deal beyond that
immediately below; the outermost more persistent than the others, after flowering
opening flat, at least in its uppei- part spathulate-caneiform, gradually narrowing
to the base from near the upper end ; the apex broadly bidentate (in one specimen),
rusty-furfiu-iiceous externally and armed over the entire surface witli very short
and very broad, flat, often confluent or seriate or at times laciniate, slightly
deflesed, brownish spines, glabrous and shining internally ; inner spathes smaller,
deciduous, gradually less spinous, the ultimate smooth. Mah spadu erect,

very shortly podicellate, the flowering axis furfuraceous, very slender, strict
and cnpressiform-fastigiate, in one specimen 40 cm. long, with 6-7 also very
slenderly cupressiform, erect partial inflorescences; the main axis is as thick as
a pack-thread, aubterete; the branchlet.s arc numerous and carry 8-10 spikelets
which arc not bifariously «et, but turned outwards, are very small and have
a very slender filiform axis, are about I cm. ' long and have altogether 3 -4
unilaterally set flowers; spathels smd involucre inconspicuous. Fruiiinff ^padix
nodding, 85 cm. long (in one specimen), with 9-10 partial irflorescenccs and
a very short (3 cm.) unarmed, rather thick, clavaie peduncular p a r t ; all the axial
pHi-ts are covered with a thin persistent rusty-furfuraceous indumentun
main^ axis is subterete and rather ihick (6-7 mm. in diam.) in its low
and is irregularly an^iular higher up; secondary spathes small, annular,
partial inflorescences in th« fruiting stage erecto-patent, with a distinct a^^illary
callui", rather large; the intermediate are the largest and are 20 cm. long with
6 - 7 perfectly alternately bifarious and almost horizontal spikelets on each' side •
the lowest mflorescences are shghtly smaller; the ultimate are much reduced in
size and number of spikelets; the axis of the inflorescences is straight, rigid,
acutely and irregularly 3-4.gonous, almost wingod on the angles, and is gradutllynarrowed
towards the upper end; spikelets rigid, with a ciiatirct
the lower of, each of the partial inflorescences which are th.
and have 7 - 8 bifarious flowers on each side; their axes a
and somewhat sinuous ; spathels very short, annular, embra

narrowing towards the base, di,stinctly callous in its axilla, truncate, and with
a very short scale-like limb at one side at its upper end; involucre barely
protruding beyond the involucrophorum, perfectly flat-disciform with the limb reduced
to a very narrow annular rim; areola of the neuter flower smnll, pnnctiform.
