84 ANNALS OF THE LOYAL BOTANIC GARDEN, CALCUTTA. (C. viridissimus. 
and asymmetrically infundibuliform, obsoletely striately veined, slightly produced 
and apiculate on the lower side, truncate and deciduously ciliolate at the mouth 3 
involuerophorum . very shallowly cupular, immersed within its own spathel, bidentate, 
and laterally adnate to the base of the spathel above its own; involucre shallowly 
and irregularly cupular; areola of the neuter flower very depressedly lunate. Fruiting 
perianth shortly but distinctly pedicelliform; the calyx parted down almost to the 
middle into 3 triangular, slightly  striately veined, acute lobes, and with a callous 
smooth base; the segments of the corolla triangular, barely shorter than the teeth of 
the calyx. Fruit small, spherical, abruptly and comparatively stoutly beaked, 6:5 mm. 
in diameter (when not quite ripe), with a small basal acute caudiculum, which penetrates 
within the perianth; scales in 18-20 longitudinal series, glossy, convex and not 
grooved along the centre, of a dirty  straw-yellowish colour with a reddish 
slightly-produced tip and a scarious erosely-toothed margin. Seed small, globose (not 
quite mature). 
Hasirat.—The Philippines: Balete on the Rio Baco in Mindoro, collected in 
April 1905 by R, C. MeGregor (No. 309, fruiting specimen in Herb. Manila. The male 
plant has been collected in June 1907 by M. L. Merrité also in Mindoro. It is a 
commercial Bejuco (Rotang); native name **Tumalin" (No, 6217 in the Herbarium at 
Manila). 
OBSERVATIONS,—AÀ very near ally of C. Moseleyanus, from which it differs in its 
larger dimensions, in the larger and more diffuse spadix with much longer spikelets, 
and especially in the smaller fruit with more numerous and more appressed scales, which 
are arranged in 18-20 longitudinal series, while they are in 12 series only in 
C. Moseleyanus, 
SuPPL. PLATE 46.—Calamus mindorensis Bece.  Leaf-sheath with the lower 
part of a leaf; intermediate portion of a leaf; portion of the leaf cirrus; partial 
inflorescence of the fruit spadix. From MacGregor’s No. 309 in Herb. Beccari, 
143b, CALAMUS VIRIDISSIMUS Becc, n. sp. 
Description.—Scandent and rather slender. Sheathed stem 25 mm. in diameter. 
Leaf-shealhs gibbous above, very obliquely truncate and smooth at the mouth, 
 greenish-brown when dry, dull and slightly rough to the touch, being very 
minutely scabrid on the exposed part, armed with scattered, very small (5-6 mm. 
long at most) horizontal spines, which have a semi-conical base and a very sharp 
point; ligule very short, glabrous. Leaves about 16 m. long in the  pinniferous 
part; petiole quite obsolete, the leaflets extending clear quite to the base; rachis 
12-13 mm. broad at its base, where it is flattish above and convex underneath; 
a little above the base it is more convex on the upper than on tbe lower 
surface, is not grocved along the sides, where the leaflets are inserted, and is 
furnished above near the edges at about its third lower part with a line of emall 
prickles similar to those on the leaf-sheaths, otherwise the upper surface is smooth 
and is very obsoletely bifaced with a very obtuse salient angle near the upper
