C. marginatus.) BECCARI. THE SPECIES OF CALAMUS.—SUPPLEMENT. 53 
side faces: leaflets numerous, equidistant, 17-20 mm. apart on each side of the 
rachis, very regularly inserted at an angle of 45°, almost glossy on the upper 
surface, paler and dull on the lower, thinly papyraceous, rigidulous, linear- 
lanceolate or linear-ensiform, very acuminate to a slightly bristly tip, furnished 
on the upper surface with 3 sharp prominent smooth costae; on the lower surface 
the costae are not prominent and are covered throughout with very approximate 
small spinules; transverse  veinlets very fing and very approximate; margins 
quite devoid of bristles or spinules, more or less distinctly thickened, especially the 
upper, and with the marginal nerve very minutely  shagreened on the lower 
surface, when seen under a good lens; the intermediate leaflets 25-30 cm. long, 
14-16 mm. broad, the upper gradually smaller, the two of the terminal pair free at 
the base. Male spadiz , . . Female spadiz simple-decompound, flagelliform, about 
as long as the leaf-sheath flagella, and like these equally slender and differing 
only in being furnished with very few (3 in one specimen), very distant, partial 
inflorescences; the primary spathes tubular, very strictly sheathing, thinly coriaceous, 
the lowest 40 cm. long, 8-10 mm. broad, flattened, acutely two-edged, obliquely 
truncate at the mouth and with glabrous entire rim, produced at. one side 
into a triangular dorsally keeled point; the edges spinulous in the lower part, 
smooth above; the external surface is smooth and polished lower down and sprinkied 
with very small tubereuliform spinules from the middle upwards; the inner or axial 
surface is quite smooth; the following spathes are less flattened and have blunt 
edges, and the upper are almost cylindrical and minutely prickly in their upper part; 
all are entire, obliquely truncate, glabrous and smooth at the mouth; the elongate 
axial parts between two partial inflorescences are armed at almost regularly inter- 
vals with 3-nate claws; the terminal clawed flagellum is very slender. Partial 
inflorescences spring erect from inside but very near the mouth of their respective 
spathes, slender, elongate; the lowest the largest, 30-40 cm. long, terminates in a slender 
tail-like appendage and bears only 4-5 spikelets on each side; the upper partial inflores- 
cences are shorter, and have 6-7 spikelets in all; scondary spathes about 3 em, long, 
very narrowly tubular, slightly enlarged above or subclavate, very strictly sheathing, 
obliquely truncate and glabrous at the mouth, sprinkled with very minute tuberculi- 
form spinules. Spikelets attached just above the mouth of their respective spathes, 
slightiy arched, spreading or recurved, all almost of one size, about 2°5-3 cm. long, with 
5-6 flowers on each side; spathels infundibuliform, tapering to a narrow base, 
truncate at the mouth, produced at one side into a triangular, subulate, spreading 
point; involucrophorum irregularly cupular; involucre also irregularly cupular, immersed 
within and at the same level with the involucrophorum; areola of the neuter 
flower depressedly lunate, sharply edged. Female flowers, judging from the fruiting 
perianth, about 4 mm. long; the calyx and corolla apparently rusty furfuraceous. Fruiting 
perianth pedicelliform, subeampanulate; the calyx smooth and callous at the base, split 
down about to the middle into 3 semi-ovate, striately veined lobes; the segments 
of the corolla very slightly longer than the calyx, Fruit small, 12-13 mm, long, 
including the mucro and perianth, 7 mm. broad, obovoid, tapering considerably towards 
the base, and suddenly contracted above into a stout muero, 2 mm. long which is 
crowned by the  narrow-acuminate, circinate stigmas; scales arranged in 16-17 
longitudinal series, yellowish brown, with relatively broad darker reddish edges,
