C. Schlechterianus.] BECCARI THE SPECIES OF CALAMUS.—SUPPLEMENT. 119 
spikelets, which are rigid and thickish; spathels and involucrnphorum as in the other 
forms; involucre distinctly diseoid-orbieular, flat or slightly convex, Fruit larger 
than in type, globose-ovoid, 13 mm. long, about 10 mm. broad, borne on a short 
but distinctly pedicelliform cylindraccous fruiting perianth; seales shining, arranged in 
15 longitudinal series, lightly farrowed along the middle, brown with a darker 
uniform margin all round, the point blunt. 
Hasirat.—Collected by H. M. Curran and M. L. Merritt on an exposed mountain 
top in Elfinwoods at Zambales, Luzon, in 1907. Very common and the only 
Calamus found there, according to the collectors. 
Oxservations.—It differs from the type and also from the var. montalbanicus in 
its more robust stem and in its very rigid leaflets, which bear subspiny bristles on 
the mid-costa above and have conspicuous spreading spinules on the margins. The 
fruit is larger, more distinctly pedicellate, and with more distinctly furrowed scales 
than in type. Perhaps this should be regarded rather as a subspecies of C. dimor- 
phacanthus, than as a mere variety of it. 
187a. CALAMUS SCHLECHTERIANUS Becc. n. sp. 
DzscnrPTION.— Apparently scandent. Sheathed stem about 2 em. in diameter. Leaf- 
sheaths gibbous above, very densely hispid or closely beset with elastic, coarse, 
subspiny bristles from 5 to 20 mm. long, spreading or ascendent, polished and 
blackish but often discoloured; the gibbosity up to the base of the petiole is 
smooth; the ligule is about 15 mm. long and very densely hispid. Leaves 
large and elongate, almost certainly cirriferous, but the upper end is wanting in 
‘the portions of the one leaf seen by me; petiole 13 cm. long, about 1 cm. 
broad, convex and smooth below, concave above, prickly on the edges; the rachis 
in its lower part is deeply grooved at the sides, where the leaflets are inserted and 
is armed underneath with rather robust, scattered, brownisk claws; higher up the 
rachis has on the upper surface an acute salient angle and flat side faces; petiole 
and rachis are very thinly and partially rusty-furfuraceous. Leaflets numerous, 
equidistant, about 2 cm. apart on each side of the rachis, thinly but rather firmly 
papyraceous, almost equally green on both surfaces, linear-lanceolate; they narrow a little 
near the base, where the margins are suddenly reduplicate, and are gradually acuminate 
above to a fine capillary tip; they are 3-costulate, and have on the upper surface 
the side-costae more furnished with bristles than the mid-costa; on the lower surface 
the mid-costa alone is more or less bristly spinulous ; transverse veinlets numerous and 
very distinct; margins distinctly ciliate: the cilia spinuliform in the lower part, 
longer, more spreading, more approximate and more hair-like towards the apex: 
frequently and especially towards the apex the marginal hairs are accompanied at 
their base by a spinule; the intermediate leaflets are about 30 cm. long and 15-16 
mm. broad: the lowest are somewhat shorter and narrower. Male spadiz non- 
cirriferous, much shorter than the leaves, narrowly panicled, subcupressiform, composed 
of 5-6 gradually diminishing partial inflorescences issuing from subinflated, approximate 
spathes, and terminating in a narrow tail-like unarmed appendage, which is formed 
by very reduced, tubular, narrow, closely sheathing spathes; the primary spathes are 
thinly coriaceous, tubular and narrow in their lower part, but broaden and become
