256 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [C. vestitus. 
cylindraceous, densely clawed on the back, narrowed at the base, where in the 
‘attenuated’ axial portion flat or. almost channelled on the inner side, convex and 
clawed on the back; secondary spathes 3-4 cm. long, very narrowly tubular, slightly 
enlarged and somewhat loosely sheathing above, where very minutely and sparsely 
aculeolate, suddenly narrowed and flattened towards the base, obliquely truncate 
and when young furfuraceous-ciliolate at the mouth and prolonged at one side 
into a short triangular acute point, Male spadiz ultra-decompound with not many, 
lax, rather remote partial inflorescences, these inserted inside the mouth of their own 
spathe, 5. in one incomplete specimen, 15-25 cm. apart and terminating in an 
inconspicuous filiform tail-like appendix; the largest inflorescences, the lowest, in the 
specimen mentioned above 50 em. in length and with 14 secondary spathes, of which 
the lower ones bear branched or compound spikes and the others simple spikelets ; 
spikelets. inserted. just above the mouth of their own spathe with an indistinct 
axillary callus; 5-6 cm, long with 14-16 flowers on each side; spathels broadly 
infundibuliform, horizontally truncate at the mouth, strongly ard sharply striately 
veined, prolonged at one side into a very short tip; involucre subdimidiately 
cupular, laterally attached to the base of the spathél above its own, truncate and 
slightly bidentate, on the side next to the axis. Male flowers small, about 3 mm. 
long, bifarious, slightly. outwardly curved, the calyx strongly striately veined, acutely 
3-toothed ; the corolla one-third longer than the calyx with narrow acute and externally 
polished segments. Female spadiz simply decompound ; partial inflorescences elongate 
with 6-7 (and sometimes perhaps more) vermicular spikelets on each side, and 
terminated by a short (4 cm. long), filiform, .aculeolate, tail-like appendix ; 
spikelets inserted just above the mouth of. their own spathe, not callous at. the 
axilla, flexuose or slightly arched, horizontal or deflexed, 6-9 cm. long, with 5-10 
rather remote flowers on each side;  spathels as in the. male. spikelets but a little 
larger and longer; involucrophorum dimidiately cupular, laterally attached to the base 
of the spathel above its own; involucre cupular, flat, two-keeled, and. bidentate on 
the side next to the axis; areola of, the neuter flower depressedly lunate. Female 
flowers about 4 mm. long, often slightly outwardly curved, subcylindraceous with a 
conical summit; the calyx strongly striately veined, shortly 3-toothed; the corolla 
as long as the calyx. Fruit unknown. :

OnsERvATIONS.—AÀ very well-marked species distinguished by tes very large thin 
exsuccous and ultimately  lacerated and fibrous ocreas (which entirely cover the 
younger part of the stem); by the almost epetiplate leaves with numerous equidistant 
narrow leaflets; and by the elongate flagelliform spadices which are longer than the 
leaves. | a.
