each side, fine. Inflorescence subdigitate, erect ; common rhachis 
filiform, about 9 lin. long, shortly bearded at the branch axils ; 
branches solitary, simple, naked up to 4 lin., quite glabrous. Eacemes 
3-5 (or 7 according to Hackel), rather stout, more or less flexuous, 
about 2 in. long, purplish-grey ; joints and pedicels finely filiform, 
solid, £-1 lin. long, ciliate on both or only on one side, upper cilia 
longer than the joint or pedicel. Sessile spikelets imbricate, broad- 
oblong, very obtuse, 2-2J lin. long ; callus very small, shortly 
bearded. Lower glume thinly chartaceous with tips hyaline and 
whitish between the keel ends, obscurely concave on the back, 
minutely asperulous on the keels, long-ciliate from small tubercles 
placed along the margins and in a semilunar row across the glume 
just below the hyaline tip, hairy on the back, intracarinal nerves 
above 5, more marked upwards, upper glume minutely truncate, 
glabrous. Valve of lower floret linear to oblong, hyaline, glabrous 
or ciliolate ; awn of upper floret up to 9 lin. long, column puberulous. 
Anthers 1 lin. long. Stigmas exserted terminally or subterminally. 
Pedicelled spikelet $ , very similar to the sessile. Lower glume 
long-hairy all over, up to 13-nerved, upper 3- to sub-5-nerved, cilio- 
late upwards. Valve oblong, ciliate at the obtuse top . — Andropogon

Spikelets 2-nate, one sessile, the other pedicelled, more or less 
similar in shape, different in sex, except the lowermost 1-3 pairs of 
each raceme which are homogamous (<J or neuter), in many- jointed 
delicately peduncled nodding subdigitate or corymbose or sub- 
panicled racemes ; joints and pedicels filiform, much compressed, 
hyaline and balsamiferous between the thickened margins, disarti- 
culating horizontally, except in the sterile basal portion of the raceme ; 
fertile sessile and pedicelled spikelets deciduous, the former with the 
adjacent joint and pedicel, but the sterile basal pairs persistent. 
Florets 2 in the fertile sessile spikelets (lower reduced to an empty 
valve, upper $ ), 2 or 1 in the barren sessile and all the pedicelled 
spikelets, $ or neuter or quite suppressed. Fertile sessile spikelets 
dorsally compressed, awned ; callus small, minutely bearded. 
Glumes equal, thinly chartaceous ; lower truncate, 2,-keeled, with the
