Cymbopogon.\ clvji, gramine^; (Stapf). 
quite glabrous ; ligules scarious, 2-3 lin. long, rounded or truncate, 
glabrous ; blades narrow from a long-attenuated base (innovations 
and lower culm-leaves) or only very slightly so (most culm- 
leaves), tapering upwards to a long setaceous point, up to 2 ft. 
by 2 lin., green, very firm, rigid or flexuous upwards, quite 
glabrous, smooth except on the scabrid margins, midrib slender 
throughout or widened downwards and crescent-shaped in cross 
section, whitish on the upper surface, lateral nerves numerous, slender. 
Spatheate panicle decompound, narrow, densely contracted, |-1 ft. 
long, more or less interrupted downwards ; internodes 3-6, lowest 
to over 1 ft. long, upper rapidly decreasing in length, lowest 1 or 2, 
rarely 3, subtending leaves with herbaceous sheaths 2-4. in. long and 
normal often long blades ; primary branches all but the uppermost 
forming mixed tiers, the longest of their rays often long-exserted 
from the supporting sheath, 4-7-noded and bearing secondary tiers 
which before flowering imitate distichous ovate-oblong or oblong 
false spikes, axes often pubescent ; ultimate tiers usually 2-rayed, 
rays mostly 1J-2 lin. long, finely filiform, glabrous ; spathes lanceo- 
late-acute, § to £ lin. long, firmly subherbaceous with scarious 
reddish margins. Spatheoles very narrow, linear-lanceolate, finely 
acuminate, 6-8 lin. long, scarious, reddish or brownish-red ; ped- 
uncles filiform, 1J— 3 lin. long, glabrous. Racemes 2-nate, laterally 
exserted, ultimately often more or less divaricate, dense, 4—5 (or 
sometimes 6) lin. long, pale green, more or less tinged with red or 
brown, hardly villous at all, one subsessile, the other with a hairy 
bare base, J lin. long, the base of the subsessile raceme very 
short and somewhat stout, the adjacent pedicel very short, linear, 
not swollen ; fertile joints slender, filiform, £ lin. long, hairy on 
the back and sides, cilia up to J lin. long, tips cupular, minutely 
and unequally 2-auriculate ; adjacent pedicels very similar to the 
joints, £-1 lin. long. Homogamous pair of spikelets 1 at the 
base of the sessile raceme. Fertile spikelets oblong or oblan- 
ceolate-oblong, 2 j-3 lin. long, pale, reddish upwards, glabrous ; 
callus very short, obtuse, shortly bearded. Glumes subequal, 
thinly chartaceous, lower 2-toothed, flat on the back or very slightly 
depressed towards the base or with a faint shallow median groove ; 
keels distinctly winged above the middle, wings pale or reddish, intra- 
carinal nerves usually 2, percurrent from the base to near the tips, 
green like the keel-nerves ; upper glume boat-shaped, acute, acutely 
keeled and often narrowly winged, 1-nerved, hyaline margin narrow, 
ciliolate. Lower floret reduced to a lanceolate-oblong hyaline 
nerveless ciliate valve up to over 2 lin. long. Upper floret ^ : 
valve very narrow, subchartaceous and almost stipe-like below the 
insertion of the awn, 2-fid to one-third, segments finely subulate- 
ciliolate ; awn very fine, about 5 lin. long, bent at and twisted 
below the middle ; bristle spreading at right angles or almost so. 
Anthers 1£ lin. long. Pedicelled spikelets oblong, acute, 2|-3
