Portion of the stem with a spadix in fruit and the seed in the lower part

(Herb. Kew.'; spadix with two detached fruits and portion of leaf from 
a specimen collected by Warburg also in the Aru Islands (Herb. Berol.).

Description —Rather robust. Leaf-sheaths covered with an almost black, removable, 
crustaceous scurf and densely armed with unequal more or less broadly laminar and 
often seriate black spines. Leaves exactly like those of C. melanochaetes, but sometimes 
bristly on 5 nerves above. Spadices 40-60 cm. long, including the beak which is about 
as long as the body or shorter, and spinous only at its base; otherwise the spadices 
are exactly like those of OC. melanochaetes except that the outer spathe is densely 
armed with many, more or less broadly laminar, black spines, which are usually 
confluent by their bases and more or less partially or interruptedly transversely 
seriate; some of these spines are 3-4 mm. broad at their bases and 4-5 cm. long, 
intermingled with smaller ones; those of the basal part of the body ure reversed, 
those of the middle horizontal, the upper ones, and especially those of the base 
of the beak, ascendent and often longer than the others; the second and third spathe 
also spinous, but in a far less degree. Fruit spherical, 16-18 mm. in diameter; 
scales slightly channelled along the middle, with a dark marginal line and a 
very slightly produced obtuse tip. Seed irregularly globular, strongly ventricose on 
the raphal side. 
Hasrrat.—Sumatra, in the province of Palembang. 
OBSERVATIONS.—Probably D. pulembanicus must be considered as a variety of 
D, melanochaetes, of which it possesses all the characteristics except that the spines 
clothing the outer spathe are a good deal broader and more distinctly laminar than 
in the typical forms of D. melanochaetes from Java, and also are more or less 
coalescent by their bases and interruptedly seriate. 
Of the type specimen of D. palembanicus I have seen a snl portion of 
a leaf and portions of a spadix with male flowers. The leaflets in this specimen 
are exactly like those of D. melanochaetes, are 43 cm. long, 18 mm. broad, with 
long bristles on 3 nerves above, and sparsely bristly only near the apex beneath; 
the margins are appressedly bristly-spinulous up to the apex. The spikelets of 
the male spadix are densely covered on their axial part with a rusty-furfuraceous 
.pulverulent scurf, which, if observed with a good lens, appears adherent to many, .
