Characteristics

Low creeping annual; culms slender, 15-50 cm. long, nearly simple to freely branching, with short internodes, decumbent or prostrate-spreading with ascend-ing branches; sheaths usually much shorter than the internodes, sparsely to densely papillose-hispid, the margins densely ciliate; blades broadly lanceolate-elliptic, often asymmetrical, acuminate, 1.5-5 cm. long, 5-15 mm. wide, glabrous to pubescent or hirsute, the margins scabrous; inflorescence 1-6 cm. long, frequently long-exserted, of 3-6, rarely 10, short approximate racemes, the axis densely villous, flexuous; racemes 0.5-2 cm. long, ascending, the rachis densely villous; spikelets 3 mm. long, usually densely villous; glumes minutely lobed, about 2 mm. long, the second a little longer than the first; awns antrorsely scabrous, that of the first glume 10-14 mm. long, of the second 3-8 mm. long; sterile lemma minutely lobed, awnless, or with an awn 1-3 mm. long; fruit 2 mm. long, narrowly elliptic, acute.
