C. cambojensis] BECCARl. THE SPECIES OF CALAMUs.—8UPPLEMENT. 41 
Descripiion.—Apparently scandent or subscandent?, very slender. Sheathed stem 
6-8 mm. in diameter. Leaf-sheaths not or very obsoletely gibbous above, at times 
flagelliferous, armed with very unequal, scattered, light coloured spines, of which 
some are very short or tuberculiform and others 5-10 mm. long, slender yet very 
rigid and slightly deflexed. OUerea very short, membranous, truncate. Leaves short, 
35 em, long  non-cirriferous' with very few leaflets (12-14 in all, approximate into 
3-4 distant groups; petiole short, 1°5-3 cm. long, the edges acute, prickly, concave 
on the upper surface, convex and almost smooth or more or less prickly on the 
back; rachis angular, armed on the lower surface with small, solitary and very 
irregularly scattered claws; leaflets approximate in pairs on each side of the rachis, 
"the pairs of one side usually opposite to those of the other side; the two leaflets 
of the apex are connate in their basal part or up to about the middle; all leaflets 
are exactly elliptical-lanceolate or narrowly elliptical, taper equally to both ends, 
have the base acute and the apex briefly acuminate and bristly, are membranous or 
thinly papyraceous, light green when dry, slightly paler on the lower than on the 
upper. surface, are obsoletely 5-costulate, but the mid-costa alone is very sharp, although 
slender, the other costae are excessively fine, all are quite smooth on both surfaces, 
or occasionally the mid-costa alone has a straggling spinule on the upper; transverse 
veinlets extremely numerous, approximate and continuous, especially conspicuous and 
sharp on the upper surface; margins ciliate with small spreading spinules; the 
leaflets of the intermediate group are 10-11 cm. long, 2-3 cm, broad or at times 
less; the 3-4 leaflets of the apical group are slightly shorter, but not narrower; 
those near the base are usually the smallest. Male spadix ...... Female spadiz 
flagelliform, very slender and flaccid, simply branched, longer than the leaves 
inserted near the mouth of the leaf-sheaths with a distinct axillary callus, 0-8-1 m. 
long, inclusive of an excessively slender, 5-8 cm. long, aculeolate, terminal appendage, 
they have very few (3-4) distant, simple, partial inflorescences; primary spathes 
tubular, all very narrow, 2-3 mm. in diameter, very closely sheathing, entire and 
truncate at the mouth, slightly produced into a brief triangular acute point, more or 
less sparse;iy armed with small claws: the lowest shorter than the following, 8-10 cm. 
long and only very slightly broader than the upper, flattened and two-edged in its 
lower part, the edges more or less prickly ; partial inflorescences inserted above the 
mouth of their respective spathe with a conspicuous axillary callus, flaccid and with a 
slender axis: the lowest (largest) is 15-20 cm. long, or at times more, and bears 
distichally 5-7 alternate, curved and deflexed spikelets on each side; secondary spathes 
. 1-2 em. long, tubular, very narrowly infundibuliform and with a slender flattened 
base, unarmed, obliquely truncate and ciliate at the mouth, slightly produced at the 
apex into a triangular acute point; spikelets inserted at the mouth of their respective 
spathes with a distinct axillary callus, 2-3°5 cm. long; their axes are subterete, 1-5 mm 
thick, and carry distichally 5-8 not very approximate flowers (female on each 
side; spathels rather broadly infundibuliform, striately veined, truncate at the mouth, 
briefly produced at one side into a broad, triangular, acute point; involucrophorum 
concave, attached laterally to the base of the spathel above its own; involucre 
suborbicular, shallowly cupular; areola of the neuter flower lunate, flat, sharply 
edged. Female flowers ovoid; the calyx finely  striately veined. Neuter flowers 
conspicuous, very similar to the female and only slightly smaller. Other parts 
unknown.
