Cymbopogon.] clvii. gramine^ (Stapf). 
peduncles 3-5 lin. long, glabrous. Racemes 2-nate, finally spreading 
at right angles or epinastically deflexed, moderately dense, 7-12 
lin. long, pale, variously tinged with dull purple, loosely villous, 
one subsessile, the other with a slender filiform bare base, almost 
1 lin. long and hairy, the pedicel of the homogamous pair also 
slender, though short; fertile joints filiform, slender, 1-1J lin. long, 
ciliate on both sides, cilia increasing upwards to more than 1 lin., 
tips obliquely auriculate and cupular ; adjacent pedicels very similar. 
Homogamous pair of spikelets 1 at the base of the sessile raceme, 
its sessile member usually slightly differing in shape from the fertile 
spikelets. Fertile spikelets linear or linear-lanceolate, acutely acumi- 
nate, 2J-3 lin. long, reddish, glabrous ; callus short, obtuse, minutely 
bearded. Glumes subequal ; lower subchartaceous, slightly de- 
pressed towards the base, otherwise flat on the back, keels acute, 
scaberulous above ; intracarinal nerves 0 or 1, short or indistinct ; 
upper glume boat-shaped, slightly curved on the back, acute, keeled 
upwards. Lower floret reduced to a hyaline linear-oblong or almost 
linear sub-2-nerved valve, ciliolate above, slightly shorter than thre 
glumes. Upper floret ^ : valve narrowly linear, acute, about 2 
lin. long, usually entire and awnless, rarely more or less 2-fid with 
a small bristle from the sinus. Anthers 1 lin. long. Pedicelled 
spikelets $ or neuter, linear to subulate-lanceolate, as long as the 
sessile, reddish, glabrous ; lower glume 5-9-nerved, upper 3-nerved ; 
valve shorter to much shorter than the glumes, hyaline, ciliolate, 
of upper floret very narrowly linear, nerveless if present at all. —

Only known in the cultivated state, very probably of Indian origin ; grown 
for the extraction of lemon oil and as a potherb. Barren specimens received 
from Uganda through the Imperial Institute also belong here.
