Hyjparrhenia .] clvii. gramineas (Stapf). 
Raceme -bases at length epinastically deflexed, 
the longer scantily bearded with stiff 
tubercle -based hairs ; spikelets tinged 
with purple or violet, hairs and cilia pale 
fulvous or those of the callus white . . . 5. 
Fertile spikelets awnless : annual 6. 
f fRacemes loose, mostly densely villous with soft fulvous 
or rufous hairs ; at length often epinastically de- 
flexed ; spikelets rather large (fertile 2^-3 lin., pedi- 
celled 3-3^ lin. long) ; spatheoles 25-40 lin. long. 
Raceme-pairs 7-11-awned, golden- or greyish-fulvous : 
perennial. 
Mature peduncles exceeding the spatheoles ; upper 
raceme with 2 homogamous ( 6 ) pairs of spike- 
lets at the base 7. 
Mature peduncles shorter than the spatheoles ; 
upper raceme with, or more often without, 1 
homogamous pair at the base 8. 
Raceme pairs 11-13-awned, densely rufously villous; 
upper raceme without a homogamous pair at the 
base ; mature peduncles equalling or exceeding 
the spatheoles : annual 9. 
**Short, compactly csespitose grasses, rarely more than 2 ft. 
high, with slender 2-3-noded culms and narrow leaf- 
blades, scanty panicles and dense rufously villous 
racemes. 
Leaf-blades under 1^ lin. wide ; spatheoles 20-30 lin. 
long (or over) ; peduncles at length 25-50 lin. long, 
and long-exserted ; racemes slender, 10-15 lin. long, 
at length spreading or epinastically deflexed ; joints 
and pedicels very obliquely truncate ... ... 10. 
Leaf-blades 1^-2^ lin. wide ; spatheoles 18-25 lin. long ; 
peduncles at length 25-33 lin. long ; racemes some- 
what stout, 7-10 lin. long, almost contiguous, rarely 
one of a pair at length spreading or deflexed ... 11.

Perennial, densely tufted : leaf -blades usually glaucous, 
f- (rarely) 1| lin. wide ; raceme-bases not epinastic 
or very rarely the lower only ; fertile spikelets 2\-2\ 
lin., pedicelled 2^-3 lin. long ; awns 9-12 lin. long 12. 
Annual : leaf -blades not glaucous, 2-4 lin. wide; raceme- 
bases conspicuously epinastic ; spikelets and awns 
longer. 
Spatheoles and peduncles 2-2f in. or the latter to 3| in. 
long ; awns 7-11 per raceme-pair ; fertile spikelets 
2f-3 lin. long, their awns li-2 in. long ; pedicelled 
and homogamous spikelets 3|-4 lin. long 13.
