upwards, clavate, pinkish above, pale below, with an oblique mem- 
branous minutely denticulate or almost entire appendage, which is 
tubular at the base and J to over 1 lin. long, hairy on the back up 
to or beyond the middle, hairs white, up to 1J lin. long ; pedicels 
slender, sublinear, slightly shorter than the joint, hairs as on the 
joint. Sessile spikelet narrowly linear-lanceolate, slightly convex 
on the back, including the bearded callus up to 4 lin. long, greenish 
or turning red. Glumes equal ; the lower subcoriaceous, more or 
less convolute, lanceolate when flattened out, produced into a narrow 
more or less 2-dentate acumen, with long white hairs on the back 
to beyond the middle, scaberulous along the keels of the beak, intra- 
carinal nerves 2, very faint or quite obscure ; upper linear, subulate 
in profile, with a long fine point, membranous, 1 -nerved, keeled 
above the middle. Lower floret reduced to a linear-lanceolate acute 
hyaline ciliolate nerveless valve, up to 2 lin. long. Upper floret $ : 
valve 2-fid. to a quarter from the base, not quite 2 lin. long, segments 
acute, glabrous ; awn 6-10 lin. long, kneed at or slightly below the 
middle, column brown, bristle white. Stamens 2 (?) ; anthers 
narrowly linear, |-1 lin. long, often much smaller. Grain very 
slender, linear, almost 2 lin. long ; embryo about half of its length. 
Pedicelled spikelet reduced to a lanceolate-subulate glume, which 
is 2-keeled with 1 intracarinal nerve and produced into a bristle- 
like awn, 3-4 lin. long, with or without minute mucros at its base, 
very rarely a rudimentary second glume. — Andropogon exilis , Hochst.
