14 ANNALS OF IHE ROYAL BOTANIC GARDEN, CALCUTTA. EG. laxiflorus: 
sharp, not very approximate; margins remotely minutely and very appressedly 
and therefore inconspicuously, spinulous; the intermediate leaflets 28-30 cm. long, 
12-13 mm. broad; the upper ones speedily decreasing in length, but not in breadth ; 
the two of the terminal pair, the smallest, free at the base. Male spadiz apparently 
long, very delicate, thrice branched; primary spathes. . . ; partial inflorescences 
elongate and lax, the only one seen by me (probably one of the lower part of 
the spadix) is 35 cm. long and twice branched, bears 2-4 branched or compound 
spikelets on each side in its basal part and 9-10 simple (also on each side) from 
the middle upwards; the axis of the partial inflorescences is filiform and in its upper 
part zig-zag sinuous; secondary spathes very tightly sheathing, very narrow and 
very slightly infundibuliform or a little enlarged at their upper end, scabridulous 
and striately veined, obliquely truncate and ciliolate at the mouth, apiculate at 
one side; the lower compound spikelets (or secondary branches of the partial 
inflorescence) are 8-10 cm. long, and have 7-8 secondary spikelets on each side; 
the other secondary branches are shorter and one after the other have fewer 
secondary spikelets, and when the simple spikelets follow these also decrease in 
length and number of flowers; all spikelets are filiform and very slender, inserted just 
outside the mouth of their respective spathes, and retained in a horizontal or even 
deflexed position by a distinct axillary callus; the largest primary spathes are 5-6 em. 
long and have 1.—13 flowers on each side; the secondary spikelets are 1-3 cm. long, 
and have proportionally fewer flowers; spathels infundibuliform, tapering a good deal 
towards the base, hairy-scabrid, truncate and entire at the mouth, produced at one 
side into a triangular acute or apiculate point; involucre almost completely exserted 
from its own spathel and laterally attached to the base of the one above, shallowly 
cupular, strongly striately veined, obscurely and obtusely bidentate on the posticous 
side. Male flowers bifariously horizontally inserted, 4-5 mm, apart on each side, 
narrow cylindraceous, 4 mm. long, and a little more than 1 mm, thick, obscurely 
apiculate; the calyx deeply cupular or urceolate, with 3 very broad and short 
acate teeth; to each tooth converge 5 very Strong, prominent nerves or ribs; the 
corolla 3 times as long as the calyx, its segments narrowly elliptic, apiculate, 
obsoletely striate externally. Female spadiz and frust unknown. S 6 
Hasnrrar.—Singapore, at Woodlands (Ridley No, 12607 in Herb, Beccari). 
OssERVATIONS.— lhis very slender species is evidently related to the Bornean 
C. zonatus, but it is at once distinguishable from that by the leaves having more 
numerous equidistant leaflets, bristly on 3 nerves on both surfaces. Good diagnostic 
characters also are the very delicate and lax male spadix; the partial inflor- 
escences very elongate, and, at least in part, twice branched ; the slender filiform 
axial parts; the secondary spathes scabrid, very narrow and elongate; the spikelets 
filiform and very delicate, with distichous and very remote flowers; the spathels 
scabridulous with an infundibuliform limb, and s very narrow base; the male 
flowers slender cylindraceous with a strongly costulate calyx, having 5 robust uerves 
or ribs converging to each of the 3 teeth; and the corolla twice as long as the 
calyx. : 
Ridley informs me that he considers his No. 12607 to be a form of C. luridus, 
and indeed this number is so quoted in Ridley's ‘‘Materials” for that species.
