232 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA: [C. Moti. 
saymmetrically evolute, bidentate and also lunately emarginate on the side next to 
e axis; areola of the neuter flower broadly  lunate, very acute at both 
sides and sharply bordered. Female flowers small, 3:5 mm. long, ovate, acute, some- 
what ventricose when in bud; the calyx deeply divided into 3 ovate, concave, acute, 
strongly striately veined lobes; the corolla with segments smooth outside, slightly 
longer than the calyx. Fruiting perianth  explanate. Fruit subspheric, about 14 
mm. in diam, minutely apiculate; scales light-yellowish, subshining, slightly 
channelled alosg the middle, with a very narrow rusty iutramarginal lice, and a 
scarious erosely toothed margin. Seed subglobose-ovoid, about 9 mm. long and 7'5 
mm, in diameter, with an even, not pitted surface and a rather deep chalazal 
fovea placed above the centre on the raphal side ; albumen equable; embryo basal,

OsseRvATIONS.—In some of the more apparent characters this approaches C. 
pseudo-tenuis of Ceylon and Lower India. It is distinguished amongst the species of 
the group by its densely criniferous leaf-sheaths, short leaves with subequidistant 
lanceolate leaflets, which are narrowed and suddenly plicate at the base, unicostate 
or plieate subtricostulate with the nerves smooth on both surfaces. I have 
referred to C. australis, the C. Jaboolum of Bailey after inspoction of the specimens 
collected by Diels and so named in the Herbarium at Berlin. Baileys €. Moti 
is an allied, but distinct species.

DzscnrPTION.— Sheafhed stem about 2:5 cm. in diam.  Leaf-sheaths cylindraceous, 
very obliquely truneate at the mouth, very densely armed with not very large 
(10-15 mm. long) spreading fulvous acicular spines, which are confluent by their 
irregularly and very closely  seriate rather swollen bases. ^ Ocreg very short, at 
first truncate, later forming a narrow border to the mouth of the Sheath where it is 
armed with crowded slender fulvescent spicule, Leaf-sheath flagella eras 
Leaves large, not cirriferous (one entire 1'8 m. in length); petiole covered (like the 
rachis) with dark furfuraceous seales, stout, about 20 em. long, almost perfectly 
cylindrical in its lower portion, narrowly and deeply channelled upwards above. 
furnished at the sides with small prickles (some of these appearing also at the sides 
of the rachis) and armed beneath along the middle with rather strong, straight, 
about 1 cm. long, slightly deflexed aculei which extend lower down along the back 
of the sheath and higher up pass into the rachis where they are transformed into 
small claws; the claws disappear in the intermediate portion of the leaf and
