Emended description.
Tufted annuals. Leaf sheaths keeled, margins fused for 4-12% their length; blades flat to convolute, surfaces scabrous. Panicles open, with (1 –)3– 27 branches at lower nodes, lower whorls sometimes sterile; branches ascending to widely spreading, scabrous angled, with pedicels mostly equalling or up to 4 × longer than their spikelets. Spikelets 1-10-flowered; glumes unequal, 1st glume 1-veined, 2nd glume 3-veined, usually reaching to less than ⅔ the adjacent lemma; rachilla internodes terete, scabrous; callus smooth, glabrous, with a round disarticulation scar; lemmas laterally compressed, weakly keeled, glabrous or short sericeous in lower half of the keel and also along the marginal veins, between veins smooth or scabrous, glabrous (rarely sericeous), 5-veined, intermediate veins obscure to distinct, margins narrowly to broadly scarious, apex obtuse to acuminate, sometimes briefly muticus. Flowers perfect, ovaries glabrous, anthers 0.2-2.8 mm long; caryopsis 1.5-2.5 mm long, narrowly elliptical, laterally compressed, fused to the palea, solid, hilum ⅛-⅙ the grain in length.
