438 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [0. inermis. 
ovate, somewhat flattened, 18-19 mm. long, 15 mm. broad and 12 mm, thick, 
strongly pitted all over its surface, the chalazal fovea central, punctiform, not very 
distinct and with a narrow channel descending from there down to the embryo; 
albumen superficially ruminate; embryo basal The fruit described above slightly 
differs from that of C. khasianus; it is larger, more ovoid and with more numerous 
scales; the seed is also more flattened and larger. I am however unable to decide 
whether it really belongs to the same species as the male plant upon which I 
consider C, nambariensis to be based.—See observations under C. quinquenervius Roxb. 
Pirate 193.—Calamus nambariensis Becc. Leaf-sheath with the base of a leaf 
and cf a male spadix; an intermediate portion of a leaf (under-surface); the 
summit of a male spadix.—From Mann’s specimen in Herb. Becc. 
PrarE 194.—Calamus nambariensis Bece. Portion of the lower part of a 
fruit-spadix and summit of the same spadix; seed from dorsal and raphal side; one 
seed longitudinally cut in two halves through the embryo; another seed transversely 
cut.—From Mann’s specimen in Herb. Becc.

Description.—High scandent and very robust. Sheathed stem 5-6 cm. in diam. 
naked canes 3 cm. in diam. with internodes 25 cm. long. Leaf-sheaths strongly 
gibbous above, light-coloured when dry, unarmed, almost polished, not or indistinctly 
longitudinally striate, obliquely truncate and naked at the mouth. Ocrea very short 
axillary, liguliform and narrowly bordering the mouth of the sheath, glabrous. Leaves 
of the upper part of the adult plant cirriferous, very large, 3 metres in length in the 
pinniferous part; the cirrus itself 2 m. long, very robust, armed at almost regular 
but gradually shortening intervals with half or three-fourth-whorls of very stout 
light based and black-tipped claws; petiole very robust, short or very short, up to 
2:5 cm. broad, quite unarmed, flat above; rachis in its first or basal portion 
rounded beneath (as is the petiole), flat above and quite unarmed all round even 
at the margins; in the intermediate portion very obsoletely angular above and 
armed beneath along the middle with a few very robust solitary claws; in its 
upper portion very obtusely bifaced above and armed beneath with 3-nate and 
when passing into the cirrus 5-6-nate confluent claws; leaflets about 80 in all, 
usually in twos on each side of the rachis, so that the leaflets of each pair are 
very close one to the other, and the pairs stand about 10 cm. apart and those of 
one side usually sub-opposite to or not very distant from those of the other side ; 
in the lower part of the leaf sometimes the leaflets form groups of 3-4 on a side, 
whilst in the upper part they are less regularly paired and are often solitary or 
almost regularly alternate, 7-8 cm. apart; those of the summit always solitary and 
more remote than the others; they are papyraceous, not very firm, rather shining 
above, opaque and slightly paler beneath, distinctly callous at their insertion, not 
very strongly 3-5-costulate; the mid-costa distinct, the other nerves slender, all 
naked on both surfaces; transverse veinlets very slender, margins rather densely
