206 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [C. uiminalis 
The male spadix of €. viminalis may be considered simply decompound like the 
female one, if we consider the partial inflorescences as bearing simple spikelets 
charged with a glomerule of flowers at each spathel; but if we consider these 
glomerules as true abbreviate spikelets, as sometimes they really are, then the 
male spadix must be called ultradecompound.

Description.—No special characters distinguish the Javan form of ©. viminalis 
from the var. fasciculatus, which name I have, assigned to all extra-Javan forms of 
€. viminalis; these forms however never are perfectly like each other when the 
specimens come from different and remote localities. In the following notes I have 
registered what I have found more worthy of observation regarding them. | 
Subvar. BENGALENSIS. Leaflets very distinctly fascicled, usually very narrowly 
lanceolate, almost equally attenuate at both ends, very variable in size, some of 
them 2 cm. long and 1'5 cm. broad, others 12 em. long and 2 cm. broad 
always densely spinulous at the margins and on the mid-costa above, but naked a 
the latter beneath, sometimes however not only the mid-costa, but one nerve on 
each side of it is also spinulose underneath. ‘The fascicles are usually composed of 
2-3 and sometimes of 4-6 leaflets on each side and are often alternate with a 
solitary leaflet interposed; all point different ways. At the apex of the leaf ver 
few leaflets are regularly approximate and in one plane; the lowest Td 
spathes are 2-keeled and armed on the margins with straight horizontal iiie : A 
upper primary  spathes tubular-cylindrical, clawed mainly on the back: the ls est 
fruiting spikelets of the largest partial inflorescences 10-12 cm. long Yap

scales in 16-18 series, shining straw-coloured or dirty-yellowish not | or dew e
