^ rr Mature sessile spikelets persistent : cultivated 
grasses (nos. 11-24). 
- Mature glumes wholly coriaceous or the lower 
with a herbaceous triangular tip, its nerves 
not visible on the back except at the tip, 
particularly when this is herbaceous (nos. 
11-19). 
y Mature panicles more or less loose, usually 
with arched or drooping branches, never 
quite compact (nos. 11-16). 
Mature spikelets closed, tightly embracing 
the grain, never obovate. 
Glumes acute to subacuminate ; panicle 
oblong, erect and sometimes secund, 
rather loose, branches and branch- 
lets fine and almost smooth ; sessile 
spikelets lanceolate to ovate or ellip-
