the following much shorter, gradually decreasing ; usually all the 
primary branches forming scanty, up to 3-rayed, tiers, the lowest 
of which are frequently mixed ; spathes, except the lowest, with 
much reduced blades, herbaceous, subglaucous, lanceolate, acuminate 
to subulate-acuminate, 1J-1 in. long; rays finely filiform, glabrous, 
1- 14 in. long. Spatheoles at length very narrow, acute to acumi- 
nate, lj-f in. long, scarious, reddish ; peduncle filiform, 3-5 lin. 
long, glabrous. Racemes 2-nate, laterally exserted, ultimately 
divaricate or epinastically deflexed, dense, § to 1 in. long, green, 
variously and usually slightly tinged with purple or red, moderately 
villous, one subsessile, the other with a linear bare base, f lin. long ; 
bases villosulous in the fork, ciliate upwards, glabrous on the back, 
tips distinctly denticulate-cupular, neither the base of the sub- 
sessile raceme nor its short adjacent pedicel swollen ; fertile joints 
filiform, up to 1J lin. long, glabrous on the back or with a line of 
hairs upwards, densely ciliate on both sides, cilia about J lin. long 
below, to over 2 lin. near the tips, these denticulate, auriculate- 
cupular ; adjacent pedicels very similar, very slightly longer. Homo- 
gamous pair of spikelets 1 at the base of the subsessile raceme. 
Fertile spikelets linear to linear-lanceolate, usually acuminate, about 
3 lin. long, greenish, glabrous ; callus short, obtuse, shortly bearded. 
Glumes subequal, thinly chartaceous, lower 2-toothed, grooved or 
depressed on the back up to or beyond the middle, then flat, keels 
rounded and often thickened and shining below, acute and scabrid 
abo ve, sometimes a slight callous gibbosity at the base between the 
keels ; intracarinal nerves usually 2 or 3 (sometimes 1 or 4) evan- 
escent downwards, green ; upper glume boat-shaped, acute, acutely 
keeled, 1-nerved, hyaline margins narrow, ciliate. Lower floret 
reduced to a narrow linear-oblong hyaline sub-2-nerved sparingly 
ciliolate valve. Upper floret ^ : valve very narrow, 2 lin. long, 
2- fid almost to the middle, almost subchartaceous below the insertion 
of the awn, segments subulate, ciliolate ; awn very fine, about 5-8 
lin. long, bent at and twisted below the middle, bristle spreading 
more or less at right angles. Anthers about lj-lf lin. long. Pedi- 
celled spikelets $ 9 linear to lanceolate-oblong, acute, 3-3 \ lin. long, 
glabrous, sometimes purplish ; glumes subequal, subchartaceous, 
lower with acute keels and 9-11 very close intracarinal nerves ; upper 
5-nerved, ciliolate, side-nerves close to each other ; valve lanceo- 
late, acute, 2-nerved, sparingly ciliolate, as long as the glumes ; anthers 
as in the fertile floret. — Andropogon plurinodis, Stapf in Dyer, FI.
