338 ANNALS. OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [(. tomentosus. 
The var. 8 rigida has been made by me the type of C. Biumei. The female 
spadix and fruit described by Blume as belonging to C. rAomboideus very probably 
are parts of a quite different species, apparently of C. Scipionum or of a very 
nearly allied species. The leaf I have seen terminates with two leaflets without 
any vestige of a cirrus between, but very probably sometimes the rachis is slightly 
"— beyond the two terminal leaflets as in C. tomeniosus. 
C. rhomboideus is very remarkable amongst all the congeners by its large 
rhomboid radiately many ccstate leaflets, it is only very closely related to and 
perhaps not specifically distinct from ©. tomentosus Bece.

I have seen no specimen of this variety, of which Miquel says that the male 
spadix has very long partial inflorescences with the lowest spikelets bearing 
21 secondary spikelets at their base (ameutis inferioribus ternis binisve) 3 inches 
(7-5 em.) long.

DzscRIPTION.—Scandent, of moderate size, 10-12 met. long (Seortechini)  Sheathed 
stem about 2 cm. in diam. Leaf.sheaths appressedly and densely covered like the 
petioles, rachises, flagella and spadices, with a white and sometimes also fuscescent 
adherent soft almost flocculent tomentum, slightly gibbous above, thick in texture 
and almost woody, faintly longitudinally costate under the insertion of the flagellum 
or of the spadix, more or less armed, chiefly in their upper part, with very 
short spines, which have a very broad swollen mammillate base covered by the 
indumentum and a very small pungent ascendent point.  Leaf-sheath flagella very 
long, in one specimen 3'ó m. in length, plano-convex in its basal portion, cylin- 
draceous upwards, where armed with black-tipped usually ternate claws. ^ Ocrea large, 
4-5 cm. long, membranous, tomentose, unarmed, prolonged externally (not in the 
axilla of the petiole) into a broadly triangular limb, this often bilobed at the summit, 
ultimately marcescent and deciduous. ^ Leaves relatively short and robust and with few 
leaflets, not cirriferous or terminating in a very short rigid unarmed or aculeolate 
prolongation of the rachis which protrudes about 1 cm. beyond the terminal pair of 
leaflets; petiole subterete or slightly compressed, with very obtuse angles, but always 
convex above, of very variable length (from 12 to 40 cm.) armed with a few 
seattered short broad-based, biack-tipped claws; rachis subterete in its first portion, 
obsoletely angular upwards where not distinctly bifaced above, and rather strongly 
armed beneath with solitary, ternate or half-whorled and even scattered claws; leaflets 
alternate or subopposite, erecto-patent, rather remote, 8-'2 «cm. apart, papyraceous,
