green, bases very short, subequal, pubescent and densely bearded 
with hairs like those of the peduncle, obliquely truncate and pro- 
duced into an ovate to oblong firm auricle up to 1 lin. long ; joints 
linear, about 1 lin. long, obliquely truncate, very densely and 
shortly ciliate ; pedicels similar but more slender. Homogamous 
pair of spikelets 1 at the base of the lower raceme only. Fertile 
spikelets linear-oblong, founded on the back to subterete, 3 lin. 
long including the callus, pale brownish upwards ; callus subacute, 
| lin. long, densely bearded on the back. Glumes equal, lower 
firmly chartaceous, minutely 2- dent ate, glabrous and smooth or 
sparingly pubescent or hispidulous to scaberulous, 7-9-nerved, 
nerves very obscure below the tips, except the middle nerve which 
becomes at length prominent between 2 fine longitudinal grooves, 
margins involute, keels very short and indistinct, scaberulous ; 
upper glume obliquely truncate, mucronulate, 3-nerved, ciliolate 
upwards, grooved along the broad round keel. Lower floret reduced 
to an oblong obtuse faintly 2-nerved ciliolate hyaline valve. Upper 
floret ^ : valves stipitiform, edentate or minutely 2-toothed, awn 
stout, 2 in. long, column dark, fulvously hispid, bristle somewhat 
paler ; valvule 0. Anthers J lin. long. Pedicelled spikelets neuter, 
reduced to the glumes, linear-lanceolate or flattened out broad 
lanceolate, 3-d lin. long ; lower glume thin, with a mucro or bristle 
up to 3 lin . long, keels rigidly ciliolate ; upper glume shorter, very 
thin, 3-nerved. Homogamous spikelets similar to the pedicelled, 
up to 5 lin. long, always muticous . — Andropogon anthistirioides,

with a creeping branched slender rhizome closely covered with small 
glabrous hard cataphylls. Culms erect or ascending from a some- 
times prostrate base, often rooting from the lower nodes, glabrous 
and smooth, slender or, in tall specimens, up to 2-| lin. thick, many- 
noded with vegetative branches from all or some of the lower nodes. 
Leaf -sheaths terete, glabrous, often ciliate along the margins, rarely 
hirsute with tubercle-based hairs or villous at the nodes, the lownst 
withering away, the middle and upper usually shorter than the 
internodes ; ligules scarious, very short, up to \ lin. long, rounded
