Annual. Culms tufted, loosely ascending, 30–60 cm tall. Leaf sheaths glabrous to pubescent; leaf blades narrowly lanceolate, 4–12 × 0.4–0.8 cm, velvety-pubescent, margins thickened and slightly wavy, scaberulous, apex acuminate; ligule short, ciliate. Inflorescence axis 6–13 cm; racemes 3–6, 2–5 cm, loosely erect to ascending; rachis triquetrous, hispid; spikelets mostly borne in loosely contiguous pairs, one spikelet subsessile, the other shortly pedicelled, single toward raceme apex, lightly appressed to axis. Spikelets elliptic, 2.5–3.5 mm, with a 0.1–0.5 mm basal stipe, glabrous, pubescent or hispidulous, acute to cuspidate; lower glume broadly ovate, 1/3–1/2 spikelet length, 5-veined; upper glume 5–7-veined; upper lemma distinctly rugose, apex acute. Fl. and fr. summer–autumn. 2n = 32, 36.
Loosely tufted annual; culms 10-70 cm high. Leaf-blades broadly linear, 2-25 cm long, 4-14 mm wide. Inflorescence of 3 racemes borne on an axis 3-10 cm long; racemes 1-8 cm long, simple or the longest with branchlets at the base, bearing mostly paired loosely contiguous spikelets appressed to the triquetrous rhachis; pedicels shorter than the spikelets, 1-2 mm long. Spikelets elliptic to broadly elliptic, 2.5-3.5 mm long, glabrous or pubescent, acute to cuspidate, with or without a stipe up to 0.5 mm long; lower glume a third to half the length of the spikelet; upper glume and lower lemma membranous, or rarely the latter coriaceous; upper lemma rugose, subacute to acute.
Spikelets elliptic to broadly elliptic, 2.5–3.5 mm. long, glabrous or pubescent, acute to cuspidate, with or without a stipe up to 0.5 mm. long; lower glume 1/3–1/2 the length of the spikelet; upper glume and lower lemma membranous, or rarely the latter coricaceous; upper lemma rugose, subacute to acute.
Inflorescence of 3–15 racemes borne on an axis 3–10 cm. long; racemes 1–8 cm. long, simple or the longest with branchlets at the base, bearing mostly paired loosely contiguous spikelets appressed to the triquetrous rhachis; pedicels shorter than the spikelets, 1–2 mm. long.
Leaf-blades broadly linear, 2–25 cm. long, 4–14 mm. wide.
Loosely tufted annual; culms 10–70 cm. high.
Superior lemma rugose, subacute to acute.
Inferior glume 1/3–1/3 length of spikelet.
Spikelets 2.5–3.5 mm. long, glabrous to pubescent, acute, with or without a short stipe up to 0.5 mm. long.
Inflorescence of 3–15 racemes, these 1–3 cm. long, simple or the longest with branchlets at the base, bearing mostly paired loosely contiguous spikelets appressed to a triquetrous rhachis; pedicels shorter than spikelets, 1–2 mm. long.
