Annual, loosely tufted grass from fibrous roots; stems sometimes solitary, erect (sometimes bent or angled at the lower nodes), (3) 6-30 (60) cm tall.
Sheaths smooth or the lower ones usually short-hairy with the hairs directed downward; blades flat or rolled, smooth or short-hairy, to 1 mm wide; ligules 0.2-0.7 mm long.
Inflorescence a narrowly erect panicle (sometimes reduced to a raceme), (1) 2-7 (20) cm long; spikelets 4-10 mm long (excluding the awns), 5- to 11- (17-) flowered, the florets closely overlapping; glumes smooth or short-hairy, the lower glumes 1- to 3-nerved, (1.7) 2-4.5 mm long, the upper glumes 3-nerved, (2.7) 3.5-5.5 (6.7) mm long; lemmas smooth or short-hairy, lanceolate, 2.7-5 (6.5) mm long, the terminal awns (0.3) 1.5-4.5 (9) mm long; rachilla internodes usually 0.5-0.7 mm long; anthers 1 (rarely 2 or 3), (0.3) 1-3.3 mm long.
Three poorly separated varieties are sometimes recognized on the basis of floret size and hairiness. All of these phases can be found in BC.
