D. mattanensis.] BECCARI THE SPECIES OF DAEMONOROPS. 117 
Blume (Rumphia l. c.) describes the outer spathe of D. ruber “aculeis crebris 
setiformibus echinata ”, probably because parts of other species had been mixed with 
the specimens studied by him, as all the species of the group of D. Draco, to 
which D. ruber belongs, have the outer spathe armed with short stout, digitate 
spines, while bristly spines on the spathes occur in species belonging to quite 
different groups. This circumstance may perhaps account for Blume not having 
recognized C. ruber Reinwardt in his own D. accedens. 
The red secretion of the fruit of D. ruber is very scanty and not worth collection.

Bot. Surv. Ind. ii, 
Description.—Scandent, of moderate size. Sheathed stem about 2 cm. in diam. Leaf- 
sheaths very slightly gibbous above, rusty-furfuraceous, not very densely armed with 
solitary, scattered, very unequal, short or long, flat,  brown-schistaceous spines ; 
the mouth sparingly spinous or at times smooth. Leaves about l:2 m, long in the pinni- 
ferous part and terminating in a rather slender cirrus; the petiole itself 30 cm, long (in 
one leaf), thickly biconvex, 8-10 mm. broad, with obtuse edges, armed beneath along the 
dorsum with rather feeble, straight, deflexed spines, and covered on the upper surface 
with numerous very small very sharp, ascendent prickles which rest on a tuberculiform 
base; the prickles longer near the base, especially on the margins; the rachis is convex 
on its upper surface and prickly in its lower portion and has a superficial furrow on 
each side where the leaflets are inserted; higher up it is bifaced and has the salient 
angle spinulous; on the lower surface it is armed along the dorsum with solitary, not 
very strong claws, which become first 3-nate, and finally 5-nate—half-whorled, but 
towards the apex only and on the cirrus; leaflets not very numerous ,36 in all in one 
specimen), sub-equidistant, remote (5-10 em. apart), papyraceous, green, slightly paler 
beneath, ensiform, gradually narrowing towards a rather acute base, and not very gradu- 
ally and rather shortly acuminate at the upper end to a subulate ciliate-spinulous tip; 
the mid-costa is acute and the side nerves slender and naked on both surfaces; the mid- 
costa alone has a few spinules on the upper surface near the apex; transverse veinlets very 
numerous, very minute and short, and under a lens give an almost granulate appearence 
to the upper surface; margins very minutely, appressedly and rather closely spinulous; 
the largest leaflets are the intermediate, 25-30 cm, long, 18-22 mm. broad. Male spadiz 
. + « + Female spadiz nodding, borne on a slender, almost unarmed, flattened, 
obtusely edged, 15-18 cm. long, peduncular part, Primary spathes . . . . . The 
flowering panicle itself is short, 16-18 cm. long, is covered in every part with a rusty- 
furfuraceous indumentum and carries a few (4—5) approximate, small, partial inflorescences, 
of which only the lower have 5-6 small spikelets in all and the upper only 1-3; 
ihe secondary spathes have a very short annular limb, slightly extended at one side 
into a short, broadly triangular point; spikelets short, the largest 2°5-3 cm. long and
