336 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA.  |(. rhomboideus. 
margins remotely inconspicuously spinulous. The leaf-sheaths are not scabrid as in 
€. pilosellus, but this has numerous equidistant smali leaflets besides other 
characteristic marks. | | 
I consider as belonging to this species a specimen of a leaf and of an entire 
male spadix preserved in the Calcutta Herbarium and collected by Lobb in 
Sarawak. ‘The leaf is 75 cm. long and bears 28 equidistant leaflets, of which 
the largest are 25-26 cm. long and 17-18. mm. broad, not differing from those 
described above, but a little more densely ciliate on both surfaces; the small portion 
of the sheath attached to the leaf is unarmed; the rachis is rusty-lanuginose and 
ciliate upwards. The spadix is more than a metre in length and is terminated 
with a small aculeolate flagellum; the spathes and spathels are glabrous and not in 
the least degree scabrid; the partial inflorescences are branched in their lower portion 
and bear many arched spreading spikelets; the male flowers are oblong, 4-5 mm. 
long, with the calyx urceolate-campanulate, broadly 3-toothed, finely striately veined ; 
the corolla twice and twice and a half as long as the calyx. 
Another male spadix from which all the flowers have fallen away, collected by 
me in Sarawak (P. B. No. 348), apparently also belongs here; it has the primary 
spathes as in C. pilosellus, but they are not scabrid; the secondary spathes and the 
spathels infundibuliform, loosely sheathing, in their upper part glabrous and smooth; 
the involucre shallowly cupular, sessile, just outside its own spathel at the base of 
the one above.

Description.—Scandent ; of moderate size; covered on the leaf-sheaths, petiole 
leaf-rachis and spadix with a greyish short adherent furfuraceous-tomentose indumen- 
tum. Sheathed stem about 3 cm. in diam. Leaf-sheaths gibbous above, longitudinally 
striolate, sprinkled here and there with very short, conic, subtubercular spines. 
Leaves not cirriferous (or sometimes terminating in a very small and short rudi- 
mentary cirrus beyond the two end pinne) *7-1 m. long (Blume); petiole about 
30 em. long, deeply channelled and unarmed above (Blume), rounded and armed with 
scattered solitary or confluent claws beneath; rachis smooth and not very acutely 
bifaced above, rounded and sparingly armed beneath witb small claws; leaflets 
very few, 4-7 on each side, papyraceous, rather firm, opaque, green above, 
slightly | paler beneath, alternate or  subopposite, erecto-patent, broadly ovate, 
thomboidal, almost equally narrowed to both ends, cuneately attenuated, acute and
