Spikelets persistent, siibsessile, arranged in a very dense cylindrical 
or ovoid spikelike panicle, laterally compressed, nearly flat on each

in some species with the rudiment of a second neuter one above it. 
Glumes 2, equal, longer than the florets, keeled, obliquely truncate 
or acuminate, mucronate or awned, parchmentlike. Pales 2, scarious,
