Spikelets several-flowered, laterally compressed, disarticulating between the florets or the lemmas falling leaving the persistent paleas on the rhachilla; rhachilla internodes terete or rarely clavate; glumes 1-nerved, membranous, keeled, unequal, shorter than the lemmas, acute to acuminate; lemmas 3-nerved with short lateral nerves, membranous, narrow, divergent, keeled, glabrous, acuminate to shortly awned.
Inflorescence composed of numerous short stiff slender racemes of crowded spikelets arranged along an elongated central axis; racemes deciduous at maturity, the spikelets biseriate, juvenile at first and completing their growth after emergence.
Caryopsis elliptic to linear, obtusely trigonous in section.
