those of Daemonorops Hystrix. Leaves large, 1:8-2'5 m, long (King's collector), terminat- 
ing in a short, robust, strongly and irregularly clawed cirrus, which is furnished to 
its extreme summit with diminutive leaflets; petiole rather long, rounded and naked 
beneath, channelled above, armed at the sides with short straight and often divergent 
spines; rachis in its first portion somewhat flattened, slightly convex and clawed at 
the sides beneath, channelled at the sides above where are inserted the leaflets, in 
its upper part acutely bifaced and smooth above and irregularly armed beneath with 
scattered or more or less aggregate and towards the summit ternate black-tipped 
claws; ieaflets numerous, equidistant, about 3 cm. apart on each side, linear-ensiform, 
somewhat narrowed towards the base, very gradually acuminate at the summit into 
a long caudate bristly apex, thinly papyraceous, green on both surfaces, slightly 
paler beneath, with 3 costae which are very distinct, acute and bristly in the upper 
surface, and indistinct underneath where only that of the centre is bristly towards 
the summit; transverse veinlets indistinct; margins remotely, very finely and 
adpressedly spinulous; the lower margin in the upper surface often bordered with 
a very narrow shining band; the largest leaflets, those a little above the base, 
45 cm. long. 25-28 mm. broad; the upper ones gradually smaller and more distant; 
those of the cirrus abortive, 2-3 em. long and a few mm. broad.  Spadices of both 
sexes very similar in size, number and form of the spathes; with a short robust flattened 
acutely two-edged and strongly prickly peduncular part bearing very few approximate 
partial inflorescences and terminating in a long slender sparsely and irregularly 
clawed flagellum, which in its lower part is rather loosely sheathed by 2-3 strongly 
prickly spathes; primary spathes coriaceous, tubular and closely sheathing at the 
base, open on the ventral side and slightly ventricose, with a narrowly elongate sub- 
auriculiform limb upwards; this strongly armed with scattered, slender, straight- 
spreading, acicular spines; the lowest or first spathe larger than the upper ones, flattened, 
acutely two-edged and unarmed at the base, the edges gradually transformed upwards 
into two acute keels on the back of the blade; partial inflorescences very few, often. 
only oue, especially in the female spadix, and 2-3 at most in the male spadix, erect, 
densely panicled-thyrsoid, somewhat unilateral, often with the lower spikelets branched 
in the male spadix, always simple in the female one; the lowest inflorescence, the 
largest, 15-18 em. long with many very approximate gradually decreasing spikelets 
on each side and finally with solitary bifarious flowers at its summit ; the upper ones 
smaller; secondary spathes short, angular by mutual pressure, infundibuliform, truncate 
at the mouth, prolonged at one side into a triangular very acute or cinesi point. 
Male spikelets ascendent, scorpioid; the largest, the lower ones (when simple) 20-25 mm. 
long with 2 slightly convergent series of 14—15 flowers each; spathels bracteiform, 
very approximate, very broad; concave, striately veined, ciliate, the point triangular, 
longer than the involucre, this irregularly cupular, j rather deep, usually 
= pee longate or almost boat-shaped and acute at both sides. Male flowers very 
transversely i us buse immersed in the involucre and subtended by the point 
veni s 5-6 mm. long, ovoid, obsoletely trigonous; the calyx campanulate, 
of its iam Y eter divided midway down into 3 broad rather obtuse triangular 
us "on s iu poked outside, a third longer than the calyx. Female spikelets 
a x Hen ioid, short and thick, inserted just at the mouth of their own spathe ; 
ap : nid bs largest, 20-25 mm. long with two convergent series of 8-10
