Q. Reinwardtii] BEOCARI. MONOGRAPH OF THE GENUS CALAMUS. 937, 
Description,—Scandent. Sheathed stem 1°5-2°5 cm. in diam, Leafsheaths densely 
armed with straight elongate light-coloured spines, Leaves 1-l'5 m, long; petiole 
elongate, channelled above, rounded beneath, armed, chiefly at the margins, with 
scattered horizontal or spreading, elongate-subulate, rather strong spines which are inter- 
mingled with others, smaller, short-conical and having a tendency to change into claws; 
rachis bifaced above, armed beneath with irregularly scattered, rather long, straight, 
slightly deflexed solitary spines sometimes intermingled with small claws; the spines of 
the petiole and rachis light-coloured like those of the sheaths ; leaflets rather numerous, 
subequidistant, 2-4 cm. apart, linear-ensiform, thinly papyraceous but rather rigid, 
concolorous on both surfaces, shining above, attenuate at the base, gradually subulately 
acuminate into a bristly apex, distinctly tricostate, the 3 coste equally spinulous 
above, beneath the mid-costa spinulous and not very prominent, and the other nerver 
faint and naked ; transverse veinlets not very crowded, much interrupted and rather 
sharp; margins finely and appressedly spinulous; the largest leaflets, those a little above 
the base, 25-35 em. long, 15-20 mm. broad; the two of the terminal pair free at the 
base, shorter but not narrower, more obtuse and more bristly at the apex than the 
others, Male spadiz ultradecompound in its lower portion, simply decompound upwards 
elongate-flagelliform, 1-2 m. long, ending in a slender  sculeolate flagellum and 
bearing 5-8 remote partial inflorescences, which are inserted by means of a distinct 
axillary callus with a distinct transversal rima at, or a little above or shortly inside, 
the mouth of their own spathe; upper primary spathes very long, narrowly tubular, 
cylindraceous, very slightly enlarged above, prickly chiefly externally in their attenuated 
part, often split longitudinally at their summit and terminating in a narrow lanceolate 
limb, whieh is often withered and marcescent at the margins and at the apex; the 
lower partial inflorescences (the largest) 30-35 cm. long, branched again at their base; 
the upper ones gradually shorter and with a variable number of spikelets; secondary 
$pathes narrowly tubular-infundibuliform, unarmed, obliquely truncate and ciliate at the 
mouth and prolonged at’ one side into a triangular acute point; this usually withered 
and ultimately marcescent. ‘Male spikelets 2-4 cm. long, slender, filiform, patent or 
horizontal, more or less arched downwards, attached at the mouth of their own spathe 
and callous at the axilla; spathels very shortly asymmetrically infundibuliform, apiculate 
at one side, strongly veined, entire and ciliate at the margin; inyolucre cupular, rather 
shallow, exserted from its own spathel and laterally adnate to the base of ‘the one 
above. Male flowers horizontally inserted. Female spadiz more robust than the male 
one, simply decompound, flagelliform, elongate, with not many very remote partial 
inflorescences; primary and secondary spathes as in the male spadix ; partial inflores- 
€ences issuing erect from the split summit of. their respective spathe, then more or 
less spreading, rather rigid; the lower ones, the largest, as much as 45 cm. long and 
in luxuriant specimens with 15-17 spikelets on each side; the upper ones gradually 
shorter, 15-20 cm. long, with 4-8 spikelets on each side; spikelets rather. rigid, 
horizontally inserted with a distinct axillary callus, more or less arched and often 
deflexed; the lower ones, in vigorous specimens, as much as 12-13 em. in length with 
25-30 flowers on each side, but usually 6-7 cm. long with proportionally Zee. 
flowers; spathels suddenly expanded into a very short, -broadly infundibuliform, 
truncate, obtuse and, coarsely veined limb; involucrophorum: cupular, shallow, exserted 
from its own spathel and laterally. attached . to the cylindraceous’ base of its
