D. intermedius.) BECCARI. THE SPECIES OF DAEMONOROPS. 73 
D. trichrous is extremely like D. angustifolius of the Malayan Peninsula, and 
perhaps may be considered as a representative form in Sumatra and Bangka. It 
differs, however, from D. angustifolius. in the second spathe being more covered with 
spines; and in the more globular seed. The fruit of D. angustifolius is perhaps 
also more  conieally-beaked than that of D.  írichrous, and the petiole and rachis 
in this seem less prickly than in the other.

in length. 
Leaf-sheaths strongly gibbous above, more or 
less covered with a  tobaeco-coloured adherent scurf, and armed with comb-like or 
interruptedly and obliquely seriate, laminar, lanceolate, 2-3 cm. long spines, some- 
times with smaller and incomplete rows of smaller spines between the larger 
ones; the mouth obliquely truncate, not or very sparingly spinous. Leaves 
elongate, 1:6-2 m. long in the pinniferous part; petiole about 30 em. long in 
the leaves of the upper part of the plant and a good deal longer (50-60 cm. 
and more) in the lower ones, plano-convex, smooth above ín the central part, 
but usually strongly armed near and on the margins with rather long, ascendent 
or divergent, straight spines; the margins also are furnished with a few 
remote, long, stout, straight, horizontal spines which emerge from the under. 
surface; rachis smooth throughout on its upper surface, where it is convex and 
with broad side faces for the insertion of the leaflets in its first portion, with an 
obtuse salient angle in the intermediate part, that becomes very acute towards the 
apex; on the lower surface the rachis is armed at first with solitary and 
upwards with 3-5-nate claws, which become half-whorled on the terminal cirrus, 
Leaflets numerous, equidistant, not very closely set, 3-5 cm. apart, papyraceous, 
dull on both surfaces, elongate-ensiform, broad as compared with most of the species 
of the group, 35-50 cm. long, 20-35 mm, broad (the upper ones shorter and the 
lowest narrower) rather suddenly narrowing to the base and gradually acuminate 
to a filamentose tip; the  mid-costa acute, sparingly bristly towards the apex and 
with a slender nerve on each side of it (barely distinguishable from many other 
secondary nerves) more abundantly furnished with rather long bristles; on the lower 
suriace the mid-costa rather closely bristly throughout; the margins minutely 
and appressedly spinulous, the lower one bordered on the upper surface by a 
polished, very neat band.  Spadices erect, sessile or almost so, and frequently spuriously 
axillary, ventricose-fusiform, gradually narrowing into a long beak and with a slender 
base, 45-50 cm. long on the whole; outer spathe acutely two-keeled, narrowly
