Panicles of several spicate primary unilateral branches; branches in verticils (some closely positioned on the central axis), ascending, terminating in a spikelet, spikelets in two rows. Spikelets solitary, laterally compressed, disarticution above the glumes, awned, sessile or subsessile; florets 3-4, (lower 2 perfect), reduced florets at apex, rachilla not extended beyond upper floret, awned; glumes 2, 1-veined, unequal, shorter than first floret, glabrous, awned; lemmas 3-veined, coriaceous, glabrous, apex acute, 3-awned; awns apical; paleas 2-veined, awnless, glabrous.
