304 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [@. platyspathus. 
shallow, bracteiform, irregularly trigonous-tridentate; areola of the neuter flower. 
punctiform, sometimes accompanied by two very small bracteolae, Female flowers 
elongate-conic, acute, 2:5 mm. long; the calyx finely striately veined, shortly and 
acutely 3-dentate; the corolla barely longer than the calyx, its segments lanceolate, 
acuminate, finely striately veined; filaments of the stamens united by their bases 
and forming a cup which is crowned by 6 triangular teeth; these with subulate 
and inflected apex; anthers halbert-sagittate, flattened and sterile. Neuter flowers 
almost as large as the female ones. Fruiting perianth shortly pedicelliform. Frucié 
very small (not seen perfectly ripe). 
Hasirat.—Tavoy in Tenasserim, Wallich No. 8609 in Herb. Kew.; Helfer Nos. 
6390, 6396, 6398 in Herb. Kew.; the No. 6390 also in St. Pet. Herb. 
OBSERYVATIONS.— Very similar to but distinct from C. Guruba by its lanceolate 
leaflets with 5 bristly nerves above, the mid-costa only acute and the side-nerves very 
slender; from other species and mainly from C, platyspathus, to which it is also related 
and which it much resembles in the spadices, this differs in the lanceolate closely 
set equidistant numerous concolorous leaflets and in the spathes somewhat lenger than 
the inflorescences. The description of the female spadix is derived from  Wallich's 
specimen with immature fruit (No. 8609 in Herb. Kew.). 
Pirate 116.—Calamus nitidus Mart. The summit of a leaf (lower surface); a pair 
of leaflets (upper surface); two portions of male spadices.—From Helfer's specimens

Drscription.—Slender, scandent, Sheathed stem 7 cm, in diam. (in one specimen), 
Leaf-sheaihs armed with ratber numerous, very unequal, straight flat subulate narrow 
norizontal spines. Ocrea elongate, membranous, exsuccous. Leaves short, non-cirriferous : 
petiole short, rachis bifaced, very acute and smooth above, roundish beneath in ith 
first portion, where armed with a few long (1-2 cm.), straight, rather strong, usually 
solitary, slightly deflexed, subulate, dark-tipped spines, which leave deep impressions on 
the rachis, have a broad base and are transformed upwards into relatively robust 
irregularly and remotely scattered claws; these with a rather long and strongly 
deflexed point; leaflets very few, 8-12 cm. apart, all about of the same size and 
shape, the larger ones 30 cm. long and 25-28 cm. broad; the two of the terminal 
pair a few cm. shorter and quite free at the base, elongate-lanceolate or broadly 
ensiform, attenuate at the base, gradually acuminate into a subulate apex, streaked 
above with a few narrow longitudinal shining bands of which one is near the lower 
margin; otherwise the upper surface is opaque with 5-6 not very strong but acute
