478 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [C.- microcarpus 
or pergamentaceous, glabrous, finely longitudinally striolate, prolonged at the summit 
into a short triangular acute point, shortiy split on the ventral side at the summit, 
naked at the mouth; partial inflorescences inserted far inside the mouth of their 
respective spathe with a distinct elongate pedicelliform part, short, diffuse, with few 
(3-4) spikelets on each side, of which the lower ones occasionally branched; their axis 
rigid, zig-zag-sinuous; secondary spathes tubular, slightly infundibuliform not very 
closely sheathing in their upper part, finely longitudinally striate, horizontally truncate, 
entire, and scarious at the margiu, very shortly apiculate at one side; spikelets 
spreading, attached far above the mouth of their respective spathe or about midway 
up the axial part between two spathes. filiform, rigid, cylindraceous, slightly zig-zag- 
sinuous between the flowers, 4-5 cm, long, with 10-12 horizontal flowers on each 
side; spathels tubular-cylindraceous at the base, suddenly expanded at the summit into 
a short annular truncate scarious limb; involucrophorum laterally attached outside its 
own spathel at the base of the one above, sessile, explanate,  scale-like; involucre 
irregular, also scale-like with a broad, circular, flat area for the insertion of the flower ; 
areola of the neuter flower small, depressed, callous. Female flowers very small (3 mm. 
long); calyx tubular with 3 short very broad triangular teeth; segments of the corolla 
ovate, somewhat longer than the calyx. Fruiting perianth distinctly pedicelliform, the 
base flat. Fruit very small, globose, 6-7 mm. in diam., with a very shortly conic 
mucro; scales comparatively large and few, in 12 series, greyish, shining, deeply 
channelled along the middle and distinctly gibbous near the point, this obtuse, the 
margin scarious, ciliolate, Seed very small, globular, 4 mm. in diam: coarsely and 
rather deeply alveolate on the surface, with a small round and deep chalazal fovea; 
albumen bony, equable but with superficial intrusions of the integument; embryo 
basal. 
Hasirat.—The Philippines : Luzon in the Prov. Camarinas Sur, (Vidal No. 3952 
in Herb. Becc. and Kew); Central Luzon, (Loher No. 1360 and 1368 in Herb. Kew). 
. . Osservations.—Allied to C. siphonospathus from which it differs in the less 
inflated spathes, distinctly grouped leaflets, in the less branched partial inflorescences, 
and in the fruit with very deeply channelled scales. 
In the Herbarium of Berlin I have seen a specimen collected in 1841 by 
T. Jagor in Luzon which as to the leaves apparently belongs to C. microcarpus, 
with a male spadix, which hardly differs from that of the type-specimens of (€, 
siphonospathus, in the more cylindraceous and less inflated primary spathes. From 
what I can judge, the male spadices of C. siphonospathus and microcarpus are barely 
distinguishable from each other. 
Vidal’s specimen No. 3952 in my Herbarium is the upper part of a leaf and 
of a portion of a female spadix with almost mature fruit; the leaflets have the 3 
costae with long bristles above.  Loher's specimens are more complete and bear 
mature fruit; the leaflets with the costae spinulous, or with very short bristles. 
PrarE 218.--Calamus microcarpus Becc. Intermediate portion of a leaf (under 
surface); basal portion of a spadix with almost mature fruit.—From Vidal’s No. 3952
