234 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. (C. radicalis 
the plant probably climbs by the aid of the long-clawed flagellum which terminates 
the spadix. C. Moti possibly may not differ from C. radicalis which, however, is 
so imperfectly known that an exact comparison of the two is actually impossible. 
In the leaves of C. Moti I have not found any spiny bristles in the upper face of 
the rachis nor spinules on the coste of the under surface of the leaflets, but 
otherwise the ieaflets of the two plants are very much like each other. 
The characteristic marks of C. Moti are the leaf-sheaths densely armed with 
subseriate spreading spines; the large leaves with terete petiole and numerous large 
ensiform leaflets which are bristly on 3 coste above; and the spadix with a very 
long and strong terminal clawed flagellum.

flagelliferous and densely aculeate (Wendland & Drude), Leaves not cirriferous, with 
numerous equidistant leaflets (Wendland & Drude); in the small portion seen by 
me probably from the middle the rachis is fugaciously furfuraceous, flattish below, 
where armed along the middle with small solitary claws, bifaced above, where 
furnished on the acute angle with some very slender bristly spinules; leaflets 
alternate, 3 cm. apart, elongate-lanceolate or ensiform, rather suddenly plicate at the 
base, gradually long-acuminate into a subulate bristly-spinulous apex, 45 cm. long 
and 20-22 mm. broad, green even when dry, rather shining on both surfaces, 
hardly paler beneath thinly papyraceous, subtricostulate mainly near the base in the 
upper surface, where the mid-costa is acute and raised, and the side coste are 
very slender, evanescent and undistinguishable from some other secondary nerves 
towards the apex; the 3 costule are furnished above with a few long dark 
bristles; on the undersurface the mid-costa is not prominent, and on this as well 
as on 1-2 slender nerves on each side of it are some very small appressed 
spinules easily overlooked; margins wiih many very short approximate appressed. 
Spinules; lower margins slightly thickened by a slender nerve; transverse veinlets 
rather sharp, rather distant, much interrupted.— Other parts unknown.

OBSERVATIONS, — This Calamus has been described by its authors as stoloniferous, 
high scandent, with non-cirriferous leaves, which bear numerous equidistant leaflets 
and with flagelliferous densely aculeate leaf-sheaths; but the description is based on 
the specimen of only one leaf, a fragment of which I received from the late 
Baron Ferd. von Mueller, With such imperfect material it is very difficult to point
