Awned (fertile) spikelets 4-5 per raceme-pair * 
panicle large, compound ; peduncle 6-7 lin. 
long ; awns 10-15 lin. long 
Awned (fertile) spikelets usually 6-12 per raceme- 
pair. 
Racemes short, contracted, about 6 lin. long ; 
awns 3|-6 lin. long 
Racemes elongated, 7-15 lin. long ; awns 
10-15 lin. long. 
Spatheoles 12-15 lin. long; peduncles 
6-10 lin. long ; racemes 7-8 (rarely 10) 
lin. long 
Spatheoles 15-24 lin. long ; peduncles 10-20 
(rarely 25) lin. long ; racemes 10-15 lin. 
long 
**Mature peduncles equalling (or almost so) or exceeding 
the spatheoles, which after flowering are more or less 
inrolled from the margin; ratio of spatheole and 
peduncle on maturity 1 : 0*8. 
Panicle large, loose ; spatheoles broad. 12-15 (rarely 
more) lin. long ; racemes greyish-villous, awns 5-7 
per pair ; awned (fertile) spikelets 5-6 lin. long ; 
a very robust grass with blades 3-9 lin. wide 
Panicle narrow, often scanty (but see 36, H. cyanescens ) ; 
spatheoles narrower and longer than in 31, H. 
rudis ; racemes less villous to subglabrous, awns 
8-15 per pair ; awned (fertile) spikelets 4-5 lin. 
long ; leaf-blades mostly narrow. 
Panicle long and narrow or very scanty with usually 
dense racemes. 
Panicles long and narrow, borne on stiff erect 
culms ; leaf -blades long, narrow, rigid, 
narrowed towards the base and there often 
reduced to the stout semicylindric midrib ; 
racemes dark purplish, almost glabrous (except 
for the cilia of the joints and pedicels) 
Panicle rather scanty to very scanty ; culms slender ; 
leaf-blades soft. 
Mature peduncles equalling or more usually 
exceeding the narrowly inrolled spatheoles 
(ratio 1 : 0*8) ; spikelets reddish, loosely 
villous ... 
Mature peduncles equalling or rather slightly 
shorter than the spatheoles ; spikelets very 
sparingly hairy or glabrous. 
Both racemes with 1 or the lower frequently 
with 2 large homogamous pairs at the base, 
glabrous ; spatheoles and mature pedunoles 
18-22 lin. long 
The lower raceme only with 1 homogamous 
pair at the base, loosely hairy ; spatheoles 
and mature peduncles 22-35 lin. long 
Panicle large, effuse ; spatheoles up to 25 lin. long ; 
peduncles very slender, variously curved to 
cirrose upwards and subterminally exserted ; 
racemes slender, glabrous or very sparingly and 
minutely pubescent (except for the cilia)
