the apex? Upper (second) glume bicuspidate and awned between the teeth, 
Awn of the upper hermaphrodite floret 4 times as long as the spikelet. » —

Spikelets narrow lanceolate, 3 together, terminating the branches of an 
erect panicle, the central one sessile and hermaphrodite, the two lateral 
ones pedicellate and male. Glumes and flowers of Andropogon, from the 
paniculate species of which this genus differs in all the spikes being 
reduced to the terminal joint 
A genus dispersed over onsen and hye song Asia, Africa and Australia, with one 
species extending into southern 
1, C. aciculatus, Trin. Vinson p. 88. ~- Stems creeping and rooting 
at the base, then erect and stiff, about 1 ft. high, ae or branched, 
with 5—6 gine | in the lower half. Leaves crowded below, 6—3' X 3—2", 
the upper ones short with long sheaths, plane, Sisieie’ at the margins of 
the sheaths, otherwise glabrous. Ligule very short. Panicle stiff, narrow, 
2—3’ long, the erect rays about 2/s‘, pubescent, with a tuft of longer 
hairs below the spikelets. Spikelets purplish, slender, acute, glabrous, 
the lateral ones 2'/2—3” long, on pedicels 2/s the length of the sessile 
spikelet, which measures about 2”. Sessile spikelet: two outer glumes 
chartaceous, of nearly equal length, the lower lanceolate, shortly bifid, 
indistinctly nerved, biplicate slong the prominent lateral nerves and 
spinuloso-serrate along the keels, the second with one distinct nerve and 
a short mucro or awnlet, the keel spinuloso-serrate; third and fourth 
glumes shorter, hyaline, the former acute lanceolate, 3-nerved, the latter 
out into a spinulose awn 2—3” beyond the spikelet. No paleae. 
Stigmas protruding at the middle of the spikelet. Pedicellate spikelets 
lowest glume entire, second shortly mucronate, third and fourth hyaline, 
both awnless, the former ciliate at the margins. — Benth. Fl. Hongk.
