HABIT Annual. Culms erect; 20–40 cm long. Leaf-sheaths smooth. Ligule an eciliate membrane; 1–2 mm long; lacerate; truncate. Leaf-blades flat, or convolute; 1–5 cm long; 0.5 mm wide.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 1; single; smoothly terete; unilateral; 2–23 cm long. Rhachis subcylindrical and excavated. Spikelet packing broadside to rhachis; distant; regular; 2 -rowed.

Spikelets sunken; solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 4–6 fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; (2.2–)4–7 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes collateral; persistent; similar; shorter than spikelet; firmer than fertile lemma. Lower glume oblong; 1.5–2.7 mm long; 0.8 length of upper glume; coriaceous; 1-keeled; (1–)3(–5) -veined. Lower glume apex emarginate. Upper glume oblong; 1.8–3.2 mm long; 0.8 length of adjacent fertile lemma; coriaceous; 1-keeled; 5 -veined. Upper glume apex emarginate.

FLORETS Fertile lemma elliptic; 2.2–3.2 mm long; chartaceous; without keel; 5 -veined. Lemma apex entire, or dentate; 2 -fid; emarginate; muticous, or mucronate.

FLOWER Anthers 3; 0.8–1.2 mm long. Ovary glabrous.

FRUIT Caryopsis with adherent pericarp; ellipsoid; 1–1.8 mm long. Hilum punctiform.

DISTRIBUTION Europe: southwestern. Africa: north. Asia-temperate: western Asia.
