Annual. Culms loosely tufted, simple, erect or geniculately ascending, 40–60 cm tall, glabrous. Leaf sheaths hairy, at least the lower; leaf blades linear-lanceolate, flat, ca. 20 cm × 2–4 mm, glabrous or pubescent, margins scabrid, apex acuminate; ligule 1.5–4 mm. Panicle dense or slightly lax, erect, 4–15 × 2–6 cm; branches 2–3 per node, 1–3 cm, hairy, sometimes branched. Spikelets oblong, flabellate at maturity, 35–60 mm, florets 6–13, lax; lower glume subulate, 6–11 mm, 1-veined, upper glume linear-lanceolate, 10–16 mm, 3-veined; lemmas oblong, 12–19 × 3–3.5 mm in side view, 7-veined, glabrous or pubescent, margins inrolled, apex acuminate, 2-toothed; awn 12–18 mm, straight or weakly recurved; palea shorter than lemma. Stamens 2, anthers ca. 1 mm. Fl. May–Aug. 2n = 14, 28. Tufted slender annual 120-350(-600) mm high. Leaf blade 80-200 x 2-5 mm. Inflorescence contracted and dense to open, branching visible; lower branches with 1-2 spikelets, pedicels and branches shorter than spikelets, straight, robust; culm glabrous or minutely hairy below inflorescence. Spikelet 10-25(60) (including awns) x 4-5 mm, moderately laterally compressed; becoming wedge-shaped with age, hairy; lower glume 1-nerved; upper glume 14-20 mm long, 3-nerved; lemma 12-15(20) mm long, rounded on back, hairy, margins hyaline, apex distinctly bifid, acuminate, awned from well below apex; awn 15-20 mm long erect to recurved; palea ciliate on keels, glabrous between keels; callus scar circular; anthers 0.5-1.0 mm long. 10–30(–50) cm hoch, kahl oder zerstreut behaart. Blätter 4–8 mm breit. Blatthäutchen bis 3 mm lang, fein zerschlitzt. Rispe 5–15 cm lang, dicht, aufrecht, Äste schief aufrecht, meist 5–20 mm lang. Diese ohne die Grannen 2–3 cm lang. Deckspelze 12–2 4–6. Wegränder, Bahnareale, Trockenplätze, kollin. CH vereinzelt adventiv. Naturalised from southern and western Europe, eastwards to Afghanistan. Introduced and naturalised worldwide. WC (Somerset West). Annual. Culms loosely tufted, simple, erect or geniculately ascending, 40–60 cm tall, glabrous.
