34. Capillipedium. 
35. Amphilophis. 
!'7 
Sessile spikelets of the lowest 1-3 pairs £ or neuter

of $ and $ alike 36. Dichanthium. * / 
Racemes borne on subcapillary peduncles, which 
are up to over ^ in. long and usually nod- 
ding or sigmatoid ; joints and pedicels 
hyaline and balsamiferous between the 
thickened margins ; anthers of £ minute, 
about as long as broad, of £ several times 
longer than broad 37. Euclasta. 
Racemes solitary at the ends of the culms and 
branches, sometimes in scanty spatheate false 
panicles 38. Eremopogon. 
Jc. Schizaohyriastrae. 
Pedicelled spikelets not conspicuously larger than the 
sessile, very often smaller to very small ; upper 
glume awnless 39. Schizachyrium. / 
Pedicelled spikelets very much larger than the sessile, 
almost concealing them ; upper glume awned ... 40. Diectomis. ’’ 
l. Andropogonastrae. 
Racemes mostly 2-nate or sometimes digitate at the 
end of simple or almost simple culms, rarely on 
the more or less fastigiate branches of a spatheate 
false panicle ; usually all pairs heterogamous and 
all sessile spikelets $ and alike, or sometimes 
(mainly § Piestium) the lowest more or less reduced 
and barren, but still resembling the upper fertile 
spikelets ... ... 41. Andropogon. 
Racemes always 2-nate, with a spathe supporting or 
surrounding each pair, gathered into often much

matic grasses ... 42. Cymbopogon. I 
m. Hyparrheniastrae. 
Lower glume without a' herbaceous beak ; pairs of 
racemes usually in much compound spatheate 
panicles ; racemes few- to many-noded, only one

the pedicelled member of which is very similar to 
the sessile ... 43. Hyparrhenia. < C j J
