€. manillensis.) BECCARI. THE SPECIES OF CALAMUS.—SUPPLEM ENT. 99 
on Mount Apo, Distriet of Davao, at 1150 m. elevation (Elmer No. 10560, May 1909, 
specimens with almost mature fruits, native name *'Lintocan;")aud in the same locality, 
in dense humid forests along the Mainit Creek at about 1200 m. (Eimer No. 11714, 
September 1909, specimens with young fruits, native name “ Sarani"). 
It is described by Elmer as looping and climbing to the tops of the highest 
trees and extending occasionally far beyond them. It is a large and robust kind, 
with sheathed stems 5—5:5 cm. in diameter. The naked canes are about 3 cm. in 
diameter, hard, with a smooth yellowish surface and with internodes 25-30 em. long. 
Leafsheaths strongly gibbous above, armed with numerous, scattered, small spines, having 
a short (2-4 mm, long) sharp point resting on a bulbous base; ligula very short, 
glabrous. Leaves large, 2:5-3 m. long in the pinniferous part, and terminating in a 
robust clawed cirrus about as long; the petiolar part is flattened, about 45 em. 
long, 3 em. broad at its base, somewhat convex below, prickly, especially on its 
lower portion, and more strongly near the margins, and smooth along the central 
line; on the upper surface it is flat at the buse, slightly convex higher up and 
densely covered throughout with rigid, blackish, unequal, very small, or at most 
8-10 mm. long, slightly ascendant spines; the rachis is slightly convex on the 
upper surface, and also densely prickly from the base to about the middle, but higher 
up becomes almost smooth and strongly convex, finally exhibiting a not very sharp 
salient sngle, to which are attached the ultimate leaflets; on the under surface the 
rachis is slightly convex and armed near the end of the pinniferous part only 
with at first solitary, then ternate, and finally half-whorled very robust claws; on 
the long and strong cirrus, the half-or three-quarter whorls of robust claws are 
almost regularly 4-5 cm. apart. The leaflets are rather numerous, inserted at an 
angle of about 45°, not very approximate, almost equidistant, alternate or subopposite; 
on the lower and intermediate portion they are 6-8 cm. apart on each side, higher 
up more distant; they are papyraceous, tough and rigid, corrugated or plicate longi- 
tudinally, dull concolorous on both surfaces,  narrowly-lanceolate, almost equally 
attenuate towards both ends, the base acute, gradually acuminate above to a rigid 
very coarsely bristly apex, obscarely 5-7-costulate, or perhaps they may be said to be 
l-costate with 2-3 secondary nerves on each side; the mid-costa is slender and sharp, 
with usually 1-3 conspicuous rigid spinules on the upper surface at the base, otherwise 
all nerves are smooth on both surfaces; transverse veinlets very numerous, sharp and 
almost continuous across the blade; the margins rather remotely ciliate with rigid 
appressed spinules; the intermediate leaflets about 50 cm. long, 4~4°5 mm. broad: 
the lower narrower and slightly shorter: the uppermost considerably smaller. 
Male spadig . . . . Female spadix inserted near the mouth of its leaf-sheath, and 
spuriously axillary: it forms a large, diffuse, non-flagelliferous panicle, 1-1°5 m. long, 
branched into several partial inflorescences; primary spathes tightly sheathing, armed 
rather densely with very small, subbulbous, straight prickles; the lowest spathe 
somewhat flattened, 15-25 cm. long, 3 cm. broad, above very sharply edged or 
almost two-winged; the upper spathes are elongate-infundibuliform, entire, truncate and 
glabrous at the mouths and produced on one side to a dorsally keeled acuminate 
point; the partial inflorescences rise erect from inside, but near, the mouth of their 
respective spathes, and are then spreading arched: the lower ones are 70-80 cm. long 
and carry a few (6-8 on each side), rather distant spikelets, and terminate in a
