298 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [C. nematospadix 
OssERvATIONS.— The description of this species is based upon some specimens of 
the Calcutta Herbarium labelled: “I. Borneo, Lobb,” and consisting of the upper 
portion of a leaf and portions of a female spadix with immature fruit; the specimen 
of the leaf is glued on a separate sheet from that of the spadix, but I have no 
Special reason to doubt of their belonging, leaf and spadix, to the same species; 
nevertheless I think it advisable to state that I consider the species founded only on 
the specimens of the female spadix, Besides the quoted specimens of the Calcutta 
Herbarium, I have seen some others, apparently of the same gathering, preserved at 
Kew and one in the Herbarium at Berlin, which bear the label ‘‘Madras—Herb. 
Ind. Or.—Hook. f. & Th.” Another specimen of the female spadix not differing from 
the above is labelled in the Kew Herbarium: “ Courtalum, Wight. Febr. 1835 
(No. 1142);" this specimen is accompanied on the same sheet (No. 183) with a portion 
of a leaf different from that united to the fruit-spadix in the Calcutta Herbarium. 
C. Hookerianus is distinguished from C, pseudo-tenuis by the fruiting perianth 
being more distinctly callous at the base and by the very long partial inflorescence 
with long secondary spathes and with numerous and remote spikelets which are 
pushed downwards by a very conspicuous axillary callus. 
C. borneensis Miq. has been reduced by me to C. javensis var. tetrastichus, but 
owing to the uncertainty as to the native country of €. Hookerianus I have thought 
‘well not to keep the name borneensis for it.

of a spadix with immature fruit, from the specimens in the Calcutta Herbarium

Descriprion.—Scandent, rather slender. Sheathed stem 19-15 mm. in diam. 
Leaf-sheath flagelliferous, obliquely truncate at the mouth, finely striate longitudi- 
nally, rather densely armed with short (57 mm, long), flat, relatively broad, elongate- 
iriangular, slightly deflexed, scattered or subseriate Spines, which are fringed at the 
margins with scurfy scales. Leaf-sheath flagella very slender. crea glabrous, very 
shortly liguliform and narrowly bordering the mouth of the sheaths, Leaves not 
cirriferous, 80-90 cm. long; petiole rather long, somewhat flattened ; broadly and 
very superficially channelled above where entirely smooth, armed at the margins with 
remote short claws, of which some appear also on its convex back; rachis more or 
less fugaciously furfuraceous, bifaced and smooth above, convex beneath, where not 
very regularly armed along the middle with small, usually solitary claws; leaflets very 
variable in number, from 15 to 30 on each side, equidistant, linear-ensiform, 20-30 em. 
long, 1-2 cm. broad, papyraceous, dull and concolorous on both surfaces, narrowed to 
the base, gradually acuminate into a very acute tip, which is ciliate at the sides and 
prolonged into a sometimes very slender long filament, subtricostulate, or with the 
mid-costa acute and smooth (or nearly so) above and a weaker spinulous costula on each 
Side of it; beneath the mid-costa alone spinulous and the side nerves naked ; transverse 
‘yeinlets very minute, very approximate and. much anastamosing; margins smooth in 
the lower portion and inconspicuously but very finely spinulous towards the apex,
