332 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. CC. hispidulus, 
sight glabrous, but under the lens they are bristly spinulous above on the wmid-costa 
and on a secondary nerve on each side of it, and beneath are densely hairy-hispidulous 
on all nerves and at the margins; in some of the recently-eollected specimens the 
bristly nerves are 5-7 above and in others the entire upper surface is more or less 
hairy-hispid, while the lower one is densely hairy and the margins closely and 
adpressedly ciliate. Griffith’s authentic specimen, which I have seen in the Herbarium 
at Kew, has a very slender stem 6-12 mm, in diam. and the partial inflorescences 
have only 2-3 very few-flowered spikelets on each side. 
The specimen No. 10259 of the Calc. Herb. has one leaf terminating in a 
rudimentary aculeolate cirrus, which is about 1 cm. long. and projects between the 
two apical leaflets. 
Prare 130.—Calamus exilis Grif. Portion of the sheathed stem with an entire 
fruiting spadix; an intermediate portion of a leaf (under surface); the summit of a 
leaf (upper surface); seeds (ventral and dorsal side), one longitudinally cut through 
the embryo.—From No. 2737 Herb. Cale. in H. Becc.

DescripTION.—Scandent, rather slender. Sheathed stem about 18 mm. in diam. 
Leaf-sheaths flagelliferous, very densely clothed when young with coarse yellowish or 
fulvous, long, spreading, deciduous hairs resting upon bulbous permanent bases, 
and rendering scabrid the surface of the older sheaths. Leaves not cirriferous, 
about £0 cm. long; petiole 8-10 cm, long, 6 mra. broad, flattish or slightly 
channelled above, feebly armed on the margins as well as along the centre of the 
round lower surface with a few very small and slender claws, which become closer 
and somewhat stronger, but always solitary, throughout the entire rachis; this and 
the petiole are furthermore rendered scabrid by the very short bulbous hairs with 
which they are covered; leaflets not many, 11-13 on each side, rather remotely 
equidistant, thinly papyraceous or subherbaceous, very narrowly lanceolate or linear- 
lanceolate, almost equally narrowed to both ends, but very finely acuminate at the 
apex, green aud concolorous on both surfaces even when dry; in the upper surface 
the mid-costa and 3 or 4 secondary nerves on each side of it bristly-spinulous ; 
in the lower one the secondary and tertiary nerves (about 13-14 on each side of 
the mid-costa) covered with very minute hairs; margins ciliated with rather long 
and distant bristles; transverse veinlets fine, remote, short; the largest leaflets, the 
mesial, 18-20 cm. long, 10-15" mm. broad. the two of the terminal pair 
occasionally not quite opposite, free at the base. Male spadiz . , . . Female 
spadiz simply decompound, slender, about 70 em. long, including a terminal filiform, 
very finely irregularly clawed fiagellum; primary spathes very finely scabrid-papillose, 
tubular, elongate, not very closely sheathing, slightly enlarged above, obliquely 
truncate entire and  ciliolate-hispid at the mouth, prolonged at one side into a 
triangular acute point; the lowest spathe slightly compressed and acutely two-edged 
in its lower portion, the edges smooth or with a prickle here and there; the upper 
primary spathes cylindraceous, narrowed to the base, rather densely armed on the 
outer side with small scattered claws; partial inflorescences few (3-4 ) short, arising
