Cymbopogon.] clvii. gramine^i (Stapf). 
long, enclosed in or laterally exserted from the spatheole, rarely 
those of the lowest tiers longer and terminally exserted, glabrous, 
tips disarticulating, minutely cupular. Eacemes 2-nate, obliquely 
erect, hardly diverging, 7-10 lin. long, moderately villous, glaucous- 
green, sparingly tinged with purple or brown, one subsessile, the other 
with a filiform to linear slender bare base, up to over 1 lin. long, both 
bases pubescent to villous, rarely subglabrous with cupular tips, that 
of the subsessile raceme stout and short, the adjacent pedicel swollen, 
oblong, hard, glabrescent on the back and 1J lin. long ; fertile joints 
linear, 1J lin. long, minutely and rigidly pubescent on the back, 
shortly ciliate below, cilia increasing upwards to 1J lin., cupule 
oblique, auriculiform ; adjacent pedicels very similar. Homoga- 
mous or imperfect spikelet 1 at the base of the sessile raceme, very 
similar in shape to the fertile spikelets. Fertile spikelets tightly 
wedged in between joint and pedicel, linear in front view, long-acumi- 
nate, 2£-3 lin. long, greenish, sometimes purplish or violet at the tips 
and in the groove, glabrous ; callus short, obtuse, shortly bearded. 
Glumes unequal, chartaceous ; low T er obscurely 2-dentate, deeply 
and narrowly grooved up to the long flat acumen, with a callous 
gibbosity at the base, the keels obtuse and stout below the middle, 
acute and scaberulous in the acumen, intracarinal nerves 0, or 2 
short ones in the acumen close to the keels, inflexed margins narrow ; 
upper glume slightly shorter, lanceolate-oblong in profile, acute or 
mucronulate, slightly curved on the back, 1 -nerved, ciliate. Lower 
floret reduced to a narrow oblong hyaline almost nerveless ciliate 
valve, 2 lin. long. Upper floret 8 : valve narrow, linear, 2-fid to a 
quarter or almost the middle, not quite 2 lin. long, chartaceous below 7 , 
lobes linear, ciliolate ; awn slender, about 5-7 lin. long, distinctly 
differentiated into a dark brown twisted column and a yellowish 
bristle, usually bent at a right angle. Anthers 1J lin. long. Pedi- 
celled spikelet linear-lanceolate, acute, up to almost 3 lin. long, 
dull green or tinged with purple, glabrous ; glumes unequal, lower 
chartaceous with scabrid keels and 7-9 very close intracarinal 
nerves ; upper shorter, membranous, 3-nerved, hardly keeled ; 
valve linear-oblong, almost as long as the upper glume, hyaline, 
ciliate, sub-2-nerved ; anthers 1J lin. long. — Andropogon fioccosus ,

Very similar to C. commutatus, but a smaller and much more slender grass, 
and perhaps only its desert modification. The waxy (?) secretion described by 
Schweinfurth as occurring among the short hairs on the back of the joints 
(and pedicels) and in the groove of the spikelets is also present in some of Drake - 
Brockman’s specimens. The lobes of the a wned valve have always been found to 
be ciliolate although sometimes sparingly so, and not glabrous as Schweinfurth 
says of his specimens, Drake-Brockman says (in litt.) that it is also found in 
the Haud,
