454 ANNALS OF THE ROYAL- BOTANIC GARDEN, CALCUTTA.  .— iQ. ramulosus. 
broad,..3- ‘or sometimes .sub-5-costulate; all the costae very slender and naked on 
both surfaces; transverse veinlets rather distinct in the upper surface, not. very 
approximate, much interrupted. Male spadiz . . . . . Female spadic inserted far 
below the mouth of its sheath, about as long as the pinniferous part of the 
leaves, simply decompound, with 5-6 partial inflorescences, and terminating in a 
filiform tail-like appendix, quite unarmed in every part; primary spathes elongate, 
closely sheathing, papyraceous, Shortly opened at the summit on the ventral side and 
prolonged into a more or less elongate triangular point; the first flattened and 
rather acutely two-edged, the upper ones more cylindraceous; partial. inflores- 
cences ovate, panicled, spreading, inserted at the mouth of their respective spathes, 
the lower ones about 15 cm, long with 7-8 gradually diminishing spikelets on each 
side, the upper ones somewhat shorter and with fewer spikelets; secondary spathes 
tubular, slightly infundibuliform, closely sheathing, truncate at the .mouth, apiculate 
at one side; spikelets inserted far above the mouth of their own spathes, spreading, 
filiform, . the lower ones of each inflorescence about 5-6 cm. long with 10-12 
flatly bifarious horizontal flowers on each side;  spathels cylindraceous, slightly 
enlarged at the. mouth, truncate, entire, glabrous, apiculate at one side; involu- 
erophorum  disciform, laterally attached at the base of the spathei above its own 
and quite exsert from this; involucre disciform, orbicular, very: slightly concave, 
entire; areola of the neuter flower depressed, slightly callous, tumescent. Female 
flowers very small, about 2'5 mm. long, the calyx with 3 broadly ‘triangular teeth ; 
the segments of the corolla ovate, slightly longer than the calyx. ^ Fruiting ‘perianth 
distinctly pedicelliform with a flat base. Fruit very: "small, spheric, shortly but 
distinctly beaked, of the size of a coriander seed (when nearly mature); scales in 
18 longitudinal - series, A coloured. with a. red-brown e line, slightly 
channelled along the middle.

OssERvATIONs.—Related to C., ramulosus, but easily distiaguisiath by its, Ciincol 
leaf-sheaths, fescicled narrowly lanceolate leaflets, simply decompound spadix | and 
very small round fruit. Like C. ramuiosus by its natural affinities it ought to be 
included in the group with C. aruensis, but the involucrophorum is not pedicellate, 
and. on this ground it has been placed rather artificially in the group with C, inermis 
where however all the species have very large fruit. !

7 Descriprion.—Scandent, rather slender. Sheathed stem about 2 cm. in dini. iain 
sheaths cylindraceous ; gibbous above, obliquely truncate at the mouth, rather densely 
armed with seattered but somewhat regularly distributed spines which leave above 
them a deep impression on the surface of the sheath and are all of about the same.
