Andropogon. 
subclavate, 1J-2 lin. long, glossy and yellow, glabrous on the back, 
densely ciliate along the sides, hairs dirty white to yellowish, those 
of the outer edge up to 2 lin. long, tips slightly oblique, obscurely 
2-auriculate ; pedicels very similar. Sessile spikelets wedged in 
tightly between joint and pedicel, linear in face view, including 
the very small shortly bearded callus 2^-3 lin. long, yellowish below, 
greenish upwards. Glumes equal ; lower chartaceous below and 
along the rounded sides, membranous towards the middle and the 
tips, 2-mucronate or 2-aristulate, deeply grooved up to near the tips, 
densely pubescent on the back in the groove and puberulous all over 
the tips and the sides on the inner face, 2-keeled above the middle, 
with the keels scabrid, intracar inal nerves 6, close to the keels ; 
upper glume boat-shaped, emarginate, with a fine bristle about 2 lin. 
long from the notch, membranous, ciliate, 3-nerved, lateral nerves 
submarginal. Lower floret reduced to a linear-oblong valve, con- 
cave on the back, 2J lin. long, hyaline, somewhat firmer below, 
ciliate, 2-nerved. Upper floret ^ : valve broadly oblong, 2-fid to 
the middle, 2J lin. long, hyaline, 3-nerved, ciliate, segments ovate- 
lanceolate, acute, awn up to 9-10 lin. long, more or less kneed at and 
twisted below the middle, column dark, very minutely puberulous, 
bristle pale, scabrid ; valvule linear-oblong, hyaline, sub-2-nerved 
or nerveless, ciliate upwards and 1J lin. long. Anthers 2 lin. long. 
Grain oblong, 1 lin. long, subterete ; scutellum elliptic, half the 
length of the grain. Pedicelled spikelet $ , broadly oblong- 
lanceolate, subacuminate, somewhat purplish, 2J-3 lin. long : glumes 
subequal ; lower aristulate, rather flat on the back, about 13-nerved, 
keels acute, rigidly ciliolate, bristle up to 2 lin. long ; upper glume 
sub membranous, lanceolate, acute, 5-nerved, ciliolate ; valves 
linear-oblong, acute, 3-nerved, upper accompanied by a valvule like

erect, 5- or more-noded, with 2-nate or solitary barren appressed 
branches from most or all nodes, wiry, glabrous, smooth. Leaf- 
sheaths firm, the upper herbaceous, very tight, terete, produced at 
the mouth into short auricles ; ligules scarious, truncate, laterally 
adnate to the auricles of the sheath, up to \ lin. long ; blades very 
narrow, linear, long-tapering to a fine point, 3-6 in. long, up to 1J 
lin. wide, usually much narrower, dull dark green, glabrous, smooth, 
margins slightly rough ; midrib and lateral nerves fine ; subtending 
leaf with a soon convolute and very narrow sheath 1J in. long, and 
a rudimentary blade. Peduncle finely filiform, about 2 in. long,
