C. longispathus.] BECCARI. THE SPECIES OF CALAMUS.—SUPPLEMENT. 135 
thinly coriaceous, flattish or slightly concave on the axial side and has two 
very sharp spinous keels (the prolongations of the edges of the peduncular part): 
it is split longitudinally on the back, ends in a short triangular point, and 
is sprinkled throughout with small bulbous prickles; the other primary spathes are 
also very elongate, but gradually less than the first, tubular, slightly enlarged 
above from a narrow, somewhat flattened, two-edged, unarmed axial part: they are 
sprinkled with small bulbous prickles, are more or less split longitudinally in their 
upper part, and terminate in a short triangular dorsally-keeled point; the partial 
inflorescences are few (5), distant, inserted inside the mouth of their respective 
spathes, spreading, arched. the lowest about 20 cm. long and branched at the 
base:the upper ones gradually smaller: all bear & few spikelets (3-5) on each side; 
secondary spathes tubular, infundibuliform, closely sheathing, obliquely truncate 
and ciliolate at their mouths and produced at one side to a triangular acute point ; 
the spikelets have a thickish axial part and are inserted just at the mouths of 
their respective spathes with a distinct axillary callus; spathes briefly tubular- 
infundibuliform, truncate and ciliolate at the mouths; involucrophorum laterally 
adnate outside its own spathel at the base of the one above; it has a short 
annular limb and forms a short neck to the involucre which is orbicular and slightly 
concave; areola of the neuter flower lunate, sharply edged. Fruiting  perianth 
conspicuous, pedicelliform, campanulate, 5 mm. long; the calyx has a flat callous 
base and is parted down to about the middle into 3 broad acute lobes; the 
segments of the corolla are nearly twice as long as the calyx, ovate, acute, usually 
split. fruit fusiform, 15 mm. long including the  perianth and 6-7 mm. broad 
(immature): it narrows equally towards both ends and gradually tapers above to a 
stout conical beak which is surmounted by 3 short thick recurved stigmas; scales 
arranged in 12 longitudinal series, slightly convex, not grooved along the centre, 
straw-yellow with an intramarginal blackish line, and somewhat produced into 
a triangular blnntish lighter point: the margins finely erose. Sved |immature) also 
fusiform and acute at both ends, ` : 
HaBrrAT,—1 consider as typical the specimens of C. Jlongispathus forwarded to 
me by  Aidigy and bearing the No. $777. They were collected in Selangor (15th 
mile, Pahang track) near Semangkok Pass. 
OsnSERVATIONS.—I am not sure that the specimens from the other localities 
mentioned by Ridley really belong to €. longispathus, which appears to me to 
be a fine and distinct species, having only, perhaps, a certain affinity with C. 
conirostris. 
Ridley is inclined to consider the fusiform fruit of his No. 8777 as the young 
stage of the fruit of otker specimens, which in his diagnosis is described as ‘‘ large 
globose, shortly ! beaked, orange"; but although the fruit of No. 8777 is not 
perfectly mature, it has certainly almost attained its definitive form, and I do not 
think it possible that it can ever become globose, Mr. Ridley also quotes my 
authority [as to the peculiarity of the scales being ‘‘ obscurely” channelled, but 
I do not recollect having seen tili now the plant described above, and much less 
having given a description of it.
