Panicle lax, spreading, 15–25 cm; branches and pedicels longer than spikelets, ascending or nodding, filiform, flexuous. Spikelets lanceolate, 20–30 mm, florets 6–10; glumes unequal, lower glume 5–8 mm, narrowly lanceolate, 3-veined, apex acuminate, upper glume 8–10 mm, 5-veined, apex acute; lemmas narrowly oblanceolate, (8–)10–15 mm, herbaceous, margins membranous, inrolled at maturity, apex 2-toothed, teeth acuminate, 2–3 mm, awned from sinus; awn 8–17 mm, usually straight, erect or weakly recurved; palea keels pectinate-ciliate, hairs ca. 0.5 mm. Anthers 0.5–1.4 mm. Fl. and fr. May–Sep.
Tufted annual, 100-800 mm high. Leaf blade 50-300 x 2-8 mm; sheaths hairy; ligule an unfringed membrane. Inflorescence a panicle, open, nodding; culms glabrous below inflorescences; pedicels as long as to longer than spikelets. Spikelet 10-30 x 3-6 mm, laterally compressed, wedge-shaped at maturity; glumes unequal, shorter than spikelet; lower glume 1-3-nerved; upper glume 3-7-nerved. Florets 5-many; lemma back, rounded, apex acute to subacuminate, hyaline; awn 6-18 mm long, longer than lemma, straight; palea ciliate on keels, glabrous between keels; ovary with a conspicuous hairy appendage at apex; anther 0.5(-1.5) mm long. Flowering time Aug.-Feb.
