G. bicolor. | BECCARI. THE SPECIES OF CALAMUS.-- SUPPLEMENT. 197 
portion prickly only near the margins, otherwise they are smooth up to about 
the middle, and thence irregularly armed with unequal claws. Cirrus 1m. long or 
thereabout, very powerfully and densely armed with robust, long-pointed, half- 
whorled claws, and further furnished between the rows of these large claws 
with several other smaller claws, scattered or more or less confluent ; the cirrus has 
the peculiarity of being furnished up to the apex with several, distant, very rudi- 
meutary leaflets, represented by long and very slender filaments, ciliate on the edges- 
Leaflets |numerous, equidistant, 2:5-3-5 cm. apart, conspicuously discolorous, or green 
above (shiny rich green when fresh-Elmer), and covered with a thin, adherent 
chalky-white coating beneath; they are papyraceous and rather firm in texture, 
very narrowly lanceolate, tapering somewhat towards the base, and very gradually 
long-acuminate to a fine rigid tip which is produced into a capillary apex; 
the upper surface is smooth or furnished with only a few long straggling bristle. 
on the mid-costa, and also but more seldom, on one of the secondary nerves, of 
which there are 3 on each side; tertiary nerves not very prominent; on the lower 
surface the mid-costa is always (and occasionally one of the side-nerves also) 
furnished with bristles; transverse veinlets short, and much interrupted; margins 
rather closely ciliate with rigid, subspiny, ascendent hairs; the intermediate leaflets 
are 25-35 cm. long and 18-22 mm, broad, Male spadiz . . . Female 
spadix rigid, erect, non-flagelliferous ; it forms an elongate, cupressiform, acuminate, 
rather dense panicle, 40-60 cm, long, borne on an as long, or at times even 
somewhat longer peduncular part (an entire spadix seen by me is on the 
whole 1:40 cm. long, and the panicle alone about 60 cm.); the peduncular 
part is very rigid, somewhat flattened, equally convex on both faces and has the 
edges blunt lower down, and rather sharp above; it is densely covered all round 
with unequal, horizontal, scattered, rigid, usually short, straight spines; the primary © 
spathes at first entirely envelope the partial inflorescences, then split longitudinally 
down to their (bases and open flat, as in the species of the @. platyspathus group 
and appear broadly linear: finally they are slashed into several strips and fall into 
decay; the spathes are of a rather soft and thin texture, dull cinnamon-brown, 
glabrous and striate inside, covered externally with a very fine, soft, furfuraceous, 
brown indumentum; the lower primary spathes are 30-40 em. long, 2:5 em. broad, 
the others are smaller; the panicle is composed of a few (4-6) gradually decreas- 
ing partial inflorescences: its main axis is more or less prickly. The partial 
inflorescences are erect, dense, twice and in their lower parts even 3 times branched ; 
the largest (lowest 10-15 em. long, the others gradually smaller, covered more or 
Jess permanently in every part with a furfuraceous, tobacco-coloured scurf: they have 
a very short pedicellar part, conspicuously swollen at its base; all primary and 
secondary branches, and the spikelets also are conspicuously callous at their axillas; 
the secondary spathes have a very short, annular, entire limb, slightly apiculate 
at one side; the largest spikelets ithe lower ones) are 4-5 cm. long and have 5-8 
alternate flowers on each side; the axis of the spikelets is about 1 mm, thick, and 
is sinuous between the flowers; the spathels form part of the axis of the spikelets, 
and have only a very short entire annular limb slightly apiculate at one side; 
involucre almost laterally adnate at the base of the spathel above its own, irregular, 
almost explanate and usually bidentate on the posticous side; involuere subdiscoid,
