Ç. Cawa) BECCARIL MONOGRAPH OF THE GENUS CALAMUS. 357 
narrow and unequal margin; involucre also discoid, flat, orbicular; areola of the 
neuter flower callous-spongy. Female flowers in two series not disposed distinctly on 
one plane, but slightly turned upward, oblong, about 3 mm. in length; the calyx 
tubular, slightly inflated in the middle, finely striately veined, with 3 very short 
triangular acute teeth; segments of the corolla narrower and almost shorter than 
those of the calyx. Neuter flowers as long as but narrower than the female ones, 
with the calyx short, 3-gonous, acutely 3-dentate and the corolla a good deal’ longer 
than the calyx; the segments valvate and finely externally striate. Fruiting perianth 
distinctly pedicelliform. Fruit small, ovoid, distinctly suddenly mucronate, about 1 
cm, long (including the muero) and 6 mm. broad; scales in 17-18 series, reddish 
brown, slightly convex, not or slightly channelled along the middle, subshining, 
slightly prolonged into an obtuse point, with a relatively large dark intramarginal 
line; margins erosely toothed. Seed ovoid, about 6 mm. long, coarsely and irregu- 
larly pitted and grooved; the chalazal fovea narrow, in the centre of the raphal 
side; albumen equable, except for the superficial intrusions of. the crustaceous integu- 
ment; embryo basal.

Osservations.—A very near ally of C. Cawa ( Rumph. Herb. Amb. pl. 57 fig. 
1. A. B.) from which it differs in the grouped leaflets, and perhaps stil more like 
C. equesiris ( Rumph. 1. c. pl 56) which has grouped leaflets, but apparently 
unarmed leaf-sheaths or nearly so. The discovery of this species permits us to 
establish the exact position and the affinities of the two last mentioned Calams, 
which have not been found again by modern botanists, but which I consider to be 
very distinct species which doubtless still grow in the localities given by Rumph.
