at length flat, linear, tapering to a fine point, not or only slightly 
constricted at the base, often curved, from a few to 6 in. long, £-1 lin. 
wide (when flattened out), glabrous except for a few hairs near the 
base, slightly glaucous when young, turning brown when old, slightly 
rough above and on the margins, smooth below. Inflorescence 
made up of few distant flowering branches, rising solitary from the 
axils of mostly well developed leaves ; branches of 3-4 internodes, 
erect or obliquely spreading, filiform, glabrous ; spathe almost 
filiform, very acute or continued in a short subulate blade, about 
1 in. long, glabrous, at length reddish ; peduncles enclosed, filiform, 
glabrous, with minutely cupular tips. Racemes exserted from near 
the mouth of the spathe, up to 1 in. long, slender, 6-7- jointed ; 
joints clavate, cuneate from a filiform base, up to 2 lin. long, with 
urceolate crenulate tips, shortly ciliate on the outer angle from the 
base upwards, on the inner face from the middle upwards to near the 
tips, the clavate portion reddish ; pedicels similar but much more 
slender and slightly shorter, with the uppermost hairs of the outer 
angle up to 1 lin. long, those of the inner very short. Sessile spikelets 
lanceolate, including the short bearded callus 2 lin. long, pale green 
tinged with red. Glumes • subequal ; the lower thinly chartaceous, 
acuminate, 2-mucronate, almost flat on the back, glabrous, with very 
narrow inflexed margins, keels scaberulous, intracarinal nerves 4-5, 
raised upwards ; upper glume broadly rounded on the back, or 
almost flat, lanceolate, acute or mucronulate, membranous, finely 
3-nerved, ciliolate. Lower floret reduced to an oblong obtuse or 
sub-3-dentate hyaline faintly 2-nerved ciliolate valve, 1J-1J lin. 
long. Upper floret $ : valve narrowly ovate-lanceolate, very 
shortly 2-fid or 2-toothed, 3-nerved, ciliate ; awn rising from between 
the teeth, about 6-8 lin. long, kneed at and twisted below the middle. 
Anthers over 1 lin. long. Pedicelled spikelet similar to the sessile, 
but somewhat smaller and narrower, $ . Lower glume produced 
into a short bristle ; upper more boat-shaped and keeled above the 
middle. Valve of the flowering glume awnless. — Andropogon

Guin. PI. 49. Culms filiform, tough, up to over 1 ft. high ; lower 
branches few, erect, simple ; flowering branches distant, very 
slender, 2-3-nate or the upper solitary. Leaf-blades linear-lanceolate, 
rough along the margins, rarely hairy at the base ; spathes erect, 
lanceolate, with setaceous tips, not quite 1 in. long, reddish, glabrous. 
Racemes subsessile, about as long as the spathe ; joints hairy. 
Spikelets lanceolate, hairy on the sides ; awn hardly 1 fin. long,
