Plants annual; tufted, delicate. Culms 15-60(70) cm, erect to decumbent, wiry. Sheaths often inflated, sometimes with sparse hairs basally, hairs papillose-based, glabrous or the apices with small tufts of hairs, hairs to 3 mm; ligules 0.1-0.3 mm; blades 2-12(25) cm long, 0.6-2 mm wide, flat to loosely involute, glabrous abaxially, scabridulous adaxially, bases of both surfaces sometimes with a few papillose-based hairs, margins smooth or scabridulous. Panicles terminal and axillary, 1-5 cm long, 0.2-0.5 cm wide, contracted, cylindrical, enclosed in the uppermost sheath; lower nodes with 1-2(3) branches; primary branches 0.4-1.8 cm, appressed, spikelet-bearing to the base; secondary branches appressed; pedicels 0.2-4 mm, appressed, scabridulous. Spikelets 2.3-6 mm, yellowish to purplish- or grayish-mottled. Glumes subequal, linear-lanceolate to lanceolate-triangular or ovate, membranous to chartaceous, glabrous; lower glumes (2.2)2.8-4.7 mm; upper glumes (2.4)3-5 mm; lemmas (2.1)3-5.4 mm, lanceolate to lanceolate-triangular, 1-3-veined, chartaceous, often mottled with purplish or grayish areas, strigose, hairs less than 0.5 mm, apices acuminate or acute; paleas (2.1)3-6 mm, as long as or longer than the lemmas, sometimes tapering into a beak, lanceolate to lanceolate-triangular, chartaceous, strigose; anthers 3, 1.2-3.2 mm, yellowish or purplish. Fruits (1.1)1.8-2.7 mm, obovoid, laterally flattened, light brownish, translucent. 2n = 54.

It grows in disturbed sites within many plant communities, commonly in sandy to sandy-clay soils, these often derived from calcareous parent materials. Its elevational range is 1-1250 m.
