D. virescens) BECCARI. THE SPECIES OF DAEMONOROPS. 201 
diameter; the seed is almost regularly globular and 12-13 mm. in diameter or 
slightly longer than broad. Bangka specimens have a small panicle borne on a 
slender and long pedicellar part, slightly prickly only on the edges. In Ridley’s 
Singapore specimen No. 10408 the fruit is 15 mm. in diameter. Ridley’s No. 6284 has 
a male spadix with panicle 70 cm. long; the outermost spathe is 15 cm. long, the 
second 20 cm. and more acuminate.

Drscriprion.—Robust, scandent, 20—25 m. long.  Leaf-sheaihe armed with large 
robust, laminar, brown, solitary or seriate spines. Leaves large; petiole elongate, 
convex in the basal part of the lower surface, and armed along the centre of the 
dorsum with long spines, flat and prickly on the upper surface, higher up 
biconvex, armed throughout on the margins with small groups of divergent, short 
prickles; rachis clawed as usual on the back, acutely bifaced on the upper 
surface, smooth or with a spinule here and there on the salient angle. Leaflets 
numerous, inequidistant, two are often more approximate than the others but usually 
they are 4-6 cm. apart; they are ensiform, 40-50 cm. long, 2:5-3 em. broad, 
papyraceous, rather rigid, green and subconcolorous on both surfaces, sub-3-costulate or 
with the mid-costa acute and the side-costae very slender, all three very sparingly 
bristly-spinulous near the apex; on the under surface the mid-costa alone bears short 
bristles from the middle upwards; transverse veinlets excessively minute and 
numerous, but not very distinct; margins rather closely spinulous, the lower margin 
on the upper surface bordered with a narrow polished band. Mak &padiz ,........ 
Female spadiz nodding, in one specimen 75 cm. long; the panicle rather 
short and lax, and with only three partial inflorescences borne on a slender, 40 
cm. long, flattened, acutely 2-edged and smooth peduncular part; primary spathes 
deciduous...... (not seen by me); lowest partial inflorescences 20 cm. long, erect, with 
a distinct axillary callus at their insertion and with six pinnately set, gradually 
diminishing spikelets on each side; upper inflorescences much smaller, secondary 
spathes annular, sub-scarious, shortly apiculate at one side; spikelets inserted at an
