Tribe VI.—Astrept£.—Spikelets with several or ina few genera only one 
or two bisexual flowers, the rhachis usually produced and often bearing one or 
more empty glumes above them. Flowering glume unawned or with one or 
more terminal untwisted awns. Palea prominently two-nerved or two-keeled, 
usually as long or nearly as long as the glume. 
(The rhachis is not produced above the perfect flowers in Miliez, and in a 
few species of other subtribes.) 
Subtribe I—Pappophorez.—Spikelets one or several flowered, in a dense 
compound head, or in a spikelet or looser panicle. Flowering glumes rounded 
on the back, with three or more nerves leading to three or more terminal 
lobes or teeth, all unawned, or the central one or all tapering into untwisted 
awns. 
(See also Chloris, which has often a small awn or narrow lobe on each 
side of the awn, and a few Festucaces have the hyaline tip two-lobed in 
front of or on the side of the awn.)

Subtribe II.—Chloridez.—Spikelets one or several flowered, sessile in 
simple secund or unilateral spikes, which are either solitary or digitate, or 
scattered on a commonrhachis. Flowering glumes usually keeled, entire and 
unawned, or with one, rarely three untwisted awns.
