Racemes reduced to a sessile and a pedicelled spikelet ; pedicel 
finely filiform, shortly ciliate, 14 lin. long. Sessile spikelet narrowly 
lanceolate, up to 2 lin. long, including the short bearded callus. 
Glumes subequal, acuminate, glabrous below the puberulous or 
scaberulous acumen or quite glabrous except for the short scabrid 
keels ; lower chartaceous, 2-mucronate or 2-aristuiate, very finely 
5-7-nerved, somewhat flat on the back, but with the sides rounded ; 
upper glume lanceolate, subtruncate, 1-3-nerved, with a very fine 
bristle about 3 lin. long. Lower floret reduced to an oblong very 
obtuse hyaline nerveless or very obscurely 2-nerved valve, 1 \ lin. 
long, ciliate upwards. Upper floret ^ : valve lanceolate, 2-fid 
to about the middle, 1 lin. long, awn about 10 lin. long, fine, scaberu- 
lous, kneed at and twisted below the middle ; valvule 0. Anthers 
purple, 1 J lin. long. Pedicelled spikelet £ or barren, narrowly lanceo - 
late, acuminate, 2 J-3 lin. long ; glumes very similar, the lower 7-9- 
nerved, the upper 5-nerved ; lower valve 3-nerved, upper, if 
present, narrowly linear-lanceolate, very acute, 1-nerved, ciliate, 
awnless, up to 1 lin. long. — Andro'pogon trepidarius, Stapf in Journ.

Culms up to 5 ft. high, erect, glabrous, many-noded below the 
panicle. Leaf -sheaths somewhat compressed, keeled and loose, 
very firm, glabrous ; ligule reduced to a ciliolate rim ; blades linear, 
from an equally wide slightly rounded base, long-tapering, 8-12 in. 
long by 2-24 lin., convolute in bud, then flat, somewhat rigid, green, 
at length brownish, glabrous or hairy above the ligule, smooth, 
scabrid along the margins, midrib slender, prominent below. Spa- 
theate panicle subfoliate, loose, decompound to the third degree, 
up to over 1 ft. long and 5 in. wide ; primary internodes 4-5, the 
lowest 3-4 in. long, the following gradually decreasing ; primary 
tiers of 4-6 mostly compound and very unequal rays, the longest 
of the lower tiers bearing 7-5 mixed and up to 6-rayed secondary 
tiers, their compound rays with up to 4 3-2-rayed tertiary tiers ; 
ultimate rays subcapillary, f-J in. long, more or less flexuous, at 
length slightly arched or straight ; subtending leaves like the pre- 
ceding ones with well-developed blades (of the lowest up to over 
3 in. by 2| lin.), but gradually shorter upwards. Spatheoles very 
narrow, acute, scarious, 7-10 lin. long, reddish, glabrous ; peduncles 
at length exserted by 3-6 lin., capillary, glabrous, very slightly 
thickened at the tips. Racemes up to 6 lin. long, lax, with 1-4 
sessile and as many pedicelled spikelets or with an additional but 
rudimentary terminal pedicelled spikelet or barren pedicel ; joints 
subcapillary, 1J-1 lin. long, shortly ciliate ; pedicels very similar, 
shorter. Sessile spikelets narrowly linear-lanceolate, 2-2 \ lin. long,
