318 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. (C. gracilis. 
A very handsome species related only to C. Huegehanus, from which it differs in the 
sub-obpyriform fruit with rather deeply channelled scales which have a narrow 
very dark marginal line and an adpressed, very finely erosely toothed point. Some other 
specimens in the Herbarium at Kew, which probably belong to this species, have the 
leaf with numerous equidistant leaflets. One male spadix is ultradecompound recalling 
much that of C. acanthospathus, with long, 15 mm. broad, tubular closely sheathing 
spathes, armed with broad-based straight horizontal spines; the partial inflorescences 
arise erect from inside their respective spathes, then are arched with many gradually 
diminishing branchlets. 
Prate 123.—Calamus Gamblei Bece. An intermediate portion of a leaf; partial 
inflorescence with female flowers after fertilisation ; partial inflorescence with mature 
fruit, from Gamble’s type-specimen in Herb. Kew. Summit of an inflorescence of 
the var. sphaerocarpus with mature fruit, one seed entire and one longitudinally cut 
through the embryo, from Wight’s specimen in Herb. Kew. 
CALAMUS GAMBLEI var. SPHAEROCARPUS Becc. l. c. 
Fruit spherical, not tapering to the base, 18 mm. in diam.; seed also almost 
spherical. | 
Hasrar.—Nilghiri Hills, Wight in Herb, Kew; collected also by Gamble in the 
same locality.

Description.—Slender, scandent. Sheathed stem 15-20 mm.; naked canes 10-12 
mm, in diam. Leaf-sheaths green even when dry, more or less densely covered with 
a fugacious and detachable dark furfuraceous scurf, not distinctly gibbous above 
obliquely trencate and smooth at the mouth, very sparsely armed with very short 
solitary horizontal or slightly ascendent semiconic black-tipped broad-based 
sometimes almost smooth,  Leaf-sheath flagella elongate, slender, flattened and almost 
unarmed in their basal portion. Ocrea indistinct. Leaves not cirriferous, rather short 
(50-60 cm. long); petiole very short (1-3 cm. long), obsoletely trigonous, flat 
prickles ; 
above, or almost obsolete; rachis acutely bifaced and smooth above, irregularly 
armed beneath along the middle in its basal portion and also at the sides with 
solitary claws; leaflets few, all in one plane (not pointing in different directions) 
approximate into 3-4 usually opposite groups of 3-5 on each side of the rashia, 
each group separated by a long (10-15 em.) vacant space, thinly chattnodbes or 
subherbaceous, green even when dry, concolorous or barely paler beneath than above,
