126 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA, CC. bicolor: 
green above, and white beneath, exactly as in the type, from which, however, they 
differ in being smaller and in having a few bristles above on the mid-costa only, 
while the under surface is sprinkled all over, except at the base, with scattered, 
small,  spadiceous,  subspiny bristles; the largest leaflets, the mesials, are 
20-22 mm. long, and 9-10 mm. broad. Male spadiz apparently rather large, with 
several partial inflorescences each of which forms a rather dense panicle, 
20-30 cm. long, twice-branched and covered with a soft detachable whitish 
seurf on the spathes: secondary spathes! infundibuliform, rather loosely sheathing ; 
branches 10-12 em. long or at times less, bearing a few gradually decreasing 
branchlets, which carry distichally 4-6 spikelets on each side; the spikelets are 
inserted at the mouths of their respective spathes: they are 2-3 cm. long, flattened, 
comb-like, with perfectly  bifarious, horizontal, contiguous flowers; the axis of the 
spikelets is slender, not brittle; spathels very short, concave, apiculate at one side; 
very strongly and finely striately veined; involucre cupular, obliquely truncate, 
2-dentate on the axial side. Flowers small, ovoid; the calyx sharply and finely 
striately veined like the spathels, teeth 3 acute. 
HanrrAr.— The Philippines: at Cadis in Western Negros. Collected by F. 
Danao at about 50 m. above the sea No. 12452, Herb. Forestry Bureau, Manila). 
The vernacular name is “ Limoran.” 
OxssExvaTions.—The specimen upon which this variety is established consists 
only of the upper part of a leaf and of a few partial inflorescences of a male 
spadix. There is not however all the requisite evidence to prove that this specimen 
really represents the male plant of C. discolor, as the male spadix of the type, 
and the female one of this supposed variety are unknown; the leaf however of 
the plant from Negros Island, with its leaflets white beneath, though endowed with 
some peculiarities of its own, leaves little doubt as to its specific identity with 
or at least of its great affinity to 0. discolor. 
SuPPL, Puate 72.—Calamus discolor var. negrosensis Bece. Portion of a leaf; 
two partial inflorescences of a male spadix. From No, 12432 in the Herbarium 
at Manila. 
199a. CALAMUS BICOLOR Becc. n. sp. 
D:scRrPTION.— High scandent, of middling size. Naked s/e5,15-20 mm. in diameter. 
Sheathed stem 4 cm. in diameter.  Leaf-sheaths non-flagelliferous| thickish, woody, very 
densely covered with very slender, almost hair-like, unequal, elastic, brownish spines, 
4-5 em. long or less; near the mouths the spines are even longer and more 
thread-like. Leaves elongate, cirriferous, apparently about 1'5 m. long in the 
pinniferous part; the petiolar part is 15-25 cm. long, 12-15 mm. broad, somewhat 
flattened, with the two faces equally convex, and the edges bluntish; the rachis 
is convex on the upper surface a long way up from the hase and has rather 
broadly yet not deéply channelled sides where the leaflets are inserted; higher 
up it is bifaced with a prominent and prickly salient angie; petiole and rachis are 
both more or less thinly and fugaciously furfuraceous and strongly armed above 
with erect or slightly ascendent, unequal, rigid, very short or at most 8-10 mm. 
long spines; underneath petiole and rachis are slightly convex and in their lower
