Hyparrhenia.\ clvii. gramine^e (Stapf). 
the sheath-auricles ; blades very narrowly linear from an equally 
wide or gradually attenuated base, tapering to a setaceous point, up to 
2 ft. by 1 lin., firm, more or less rigid, glaucous or pale green, with the 
margins often revolute, glabrous, smooth except along the scabrid 
margins. Spatheate panicle very narrow, interrupted and scanty, 
over 1 ft. long ; internodes about 3, gradually decreasing upwards ; 
primary branches forming 3-1 upwards very scanty tiers, some of 
the lowest rays compound, 1-2-noded, all the others simple, up to 
2 in. long, subtending leaves like the preceding but upwards with more 
or less widened sheaths and reduced blades. Spatheoles narrowly 
linear-lanceolate, long-acuminate, up to If in. long, scarious, reddish 
or purplish upwards, glabrous ; peduncles filiform, apparently never 
much above \ in. long, beset almost all along with white somewhat 
stiff minutely tubercle-based hairs up to 3 lin. long. Racemes 
subcontiguous, laterally exserted from the spatheoles, about 8 lin. 
long, greenish, 2-, rarely 3-, awned per pair ; bases unequal, 
pubescent in the fork, with a dense beard of yellowish hairs about 
3 lin. long, the lower very short, the upper about 1J lin. long, 
both with a linear-oblong unequally dentate scarious whitish 
appendage ; fertile joints (if present) like the pedicels, slender, 
filiform, up to 2 lin. long, shortish white-ciliate. Homogamous 
pair of spikelets 1 at the base of the lower raceme only. 
Fertile spikelets linear-lanceolate, acuminate, somewhat flattened 
on the back with a longitudinal groove and broadly rounded sides, 
4 lin. long including the callus, greenish, glabrous ; callus slender, 
acute, white-bearded, hairs J-f lin. long. Glumes equal, chartace- 
ous ; lower 2-denticulate, with very narrow tips, 9-nerved, middle 
nerve raised in the groove, the other nerves obscure except in trans- 
mitted light, margins involute below the acumen, then indexed, 
keels fine, scabrid ; upper glume truncate, mucronate, 3-nerved, 
reversedly ciliolate. Lower floret reduced to a linear-oblong faintly 
2-nerved reversedly ciliate hyaline valve. Upper floret ^ : valves 
stipitiform, 2-dentate (teeth J lin. long), ciliolate ; awn 1J in. long, 
column fulvous, shortly hirtellous. Anthers over 1 lin. long. Pedi- 
celled spikelets linear-lanceolate, about 4-J lin. long ; lower 
glume thinly subherbaceous, shortly aristulate, 9-nerved, keels spinu- 
lously ciliolate upwards ; upper glume very acute or mucronulate, 3- 
nerved, reversedly ciliate ; valves hyaline, reversedly ciliate, the lower 
narrowly oblong, faintly 3-nerved, 3J lin. long, the upper oblanceolate, 
emarginate, 1-nerved, slightly shorter ; anthers up to 1J lin. long.
