clvii. gramine^} (Stapf). [Andropogon. 
culms up to over 1 ft. by (at the base) up to over J in., flat or con- 
volute above, rather firm, subglaucous or suffused with purple, 
glabrous or with a few scattered hairs, rough upwards on the margins 
or almost quite smooth ; midrib slender, primary lateral nerves up 
to 6 or more on each side. Inflorescence consisting of a terminal 
pair of racemes frequently augmented by 1 or 2 distant simple 1- 
noded branches or occasionally by a 2-rayed tier ; spathes linear- 
lanceolate, long-narrowed upwards, glabrous, pale green, at length 
tightly inrolled ; rays filiform, erect, strict, 2 J-6 in. long. Spatheoles 
with a generally much reduced blade similar to the spathes, about 
3 in. long, tapering to a setaceous point ; peduncles at length long- 
exserted. Racemes 2-nate, one subsessile, the other with a short 
base, 2-3 in. long, straight or somewhat flexuous ; joints and 
pedicels very similar, linear, about 3 lin. long, shortly ciliate along the 
margins ; tips produced into a very oblique obscurely denticulate 
cupule. Sessile spikelets heterogamous (except the lowest of the sub- 
sessile raceme), laterally compressed, wedged in between the pedicel 
and the joint, linear-oblong seen from the back, including the callus 
3J-4J lin. long, glabrous, green, often reddish towards the tips ; 
callus acute, up to 1 lin. long, shortly bearded. Glumes equal ; lower 
acuminate, 2-toothed, keels rounded, broad and smooth below, 
acute and scabrid near the tips, with a distinct groove or fold ex- 
tending between them to the acumen, and with 2 fine lateral furrows 
in the upper third ; upper subcoriaceous, 1 -nerved, mucronate or 
aristulate. Lower floret reduced to a lanceolate 3-nerved softly 
ciliate valve. Upper floret 8 : valve linear -lanceolate, deeply 2-fid 
with lanceolate ciliate lobes ; awn somewhat stout, 1 J to almost 2 in. 
long, kneed and pubescent below the middle ; valvule linear-oblong, 
1 lin. long, nerveless, ciliate. Anthers 1J lin. long. Pedicelled 
spikelet , lanceolate-acuminate, dorsally compressed, 5-6 lin. 
long ; lower glume subherbaceous, with many fine nerves between 
the scabrid keels, usually aristulate ; upper linear-lanceolate, 3- to sub- 
5-nerved, ciliate ; valve of lower floret membranous, linear-acuminate, 
of upper similar but shorter, 2-toothed, muticous.- — Steud. Syn. PL
