Hyparrhenia.l clvii. gramjne^e (Stapf). 
Raceme-bases not produced into a long bract-like 
appendage at the insertion of the lowest fertile" 
spikelet (§ Eu-Hyparrhenia). 
Upper raceme with or without 1 pair of homo- 
gamous awnless <? or neuter spikelets. 
Hairs of the racemes fulvous or rufous through- 
out, or at least above the callus-beards 
and lower cilia of the joints and pedicels 
which may be white ; raceme-bases not 
epinastic in most species (epinastic in 
5, H. altissima ) 
Hairs of the racemes white throughout. 
Upper glume of fertile spikelets muticous ; 
callus £-£ (rarely 1) lin. long, subacute 
to acute ; awns dark brown ; raceme- 
bases epinastic or not, upper usually 
much under 2 lin. long ; peduncles 
very slender, often much arched or 
flexuous, up to 2 or 2\ (rarely 3) in. long 
Upper glume of fertile spikelets aristulate, 
bristle up to 3 lin. long ,* callus up to 
2 lin. long, pungent ; awns (in the 
African species) almost white ; raceme- 
bases never epinastic, upper 3-5 lin. 
long ; peduncles stoutly filiform, stiff or 
more or less arched in the uppermost 
part only, up to 4-| in. long 
Upper raceme with 2 pairs of homogamous awn- 
less 6 or neuter spikelets persistent on the 
tardily disarticulating raceme-bases ; racemes 
not epinastic 
Raceme-bases produced into a long scarious bract- 
like appendage at the insertion of the lowest 
fertile spikelet, the appendage appressed to 
the latter ; racemes not epinastic (§ Ruprechtia) 
tfRaceme-bases subequal or more or less unequal, short 
and somewhat stout, dorsally flattened, rarely the 
upper elongated and subfiliform upwards. 
Raceme-bases both or at least the upper bearded 
with spreading or suberect stiff tubercle-based 
hairs ; peduncles similarly bearded near the 
tips ; racemes at length epinastically deflexed 
(§ Pogonopodia : but see also 5, H. altissima, 
and 54, H. multiplex). 
Raceme -bases not produced at the insertion of the 
lowest fertile spikelet into a scarious denticu- 
late appendage or only slightly auricled 
Raceme-bases produced at the insertion of the 
lowest fertile spikelet into a scarious usually 
denticulate appendage 
Raceme-bases not bearded (except in 54, H. multi- 
plex), although usually finely pubescent or 
villous, at least in the fork (§ Apogonia). 
Raceme-bases without a large cornucopise-like 
appendage. 
Racemes spreading, at length epinastically de- 
flexed ; glumes rather firm : perennial . . .
