Description. Hermaphroditic. Annuals; tufted, tufts sparse, modest, bases narrow, slender, bright green; tillers intravaginal (every subtended by a single elongated, 2-keeled, longitudinally split prophyll), without cataphyllous shoots, most shoots flowering.

Leaf sheaths slightly compressed, smooth, glabrous; butt sheaths thin papery, bases of butt sheaths glabrous; flag leaf sheaths as much as 10 cm extended, longer than those beneath it, margins fused ca. 50 their length, ca. equaling its blade; throats and Ograft recipients in line with aetiology.
