HABIT Annual. Culms erect; 20-57.5-100 cm long. Ligule an eciliate membrane. INFLORESCENCE Inflorescence composed of racemes. Racemes single; bilateral. Rhachis flattened. Spikelet packing broadside to rhachis; lax. Spikelets appressed; solitary. Fertile spikelets pedicelled. Pedicels oblong. FERTILE SPIKELETS Spikelets comprising 3-9 fertile florets (1), or 10-14 fertile florets, or 15-16 fertile florets (1); with diminished florets at the apex. Spikelets oblong; laterally compressed; 3-11.5-20 mm long; breaking up at maturity; disarticulating below each fertile floret. GLUMES Glumes persistent; shorter than spikelet. Lower glume oblong; 0.7-0.825-1 length of upper glume; coriaceous; without keels; 1-3 -veined. Lower glume lateral veins ribbed. Lower glume apex obtuse, or acute. Upper glume oblong; 0.7-0.875-1 length of adjacent fertile lemma; coriaceous; without keels; 3-5 -veined. Upper glume lateral veins ribbed. Upper glume apex acute. FLORETS Fertile lemma elliptic; coriaceous; without keel; 5 -veined. Lemma surface smooth (1), or scaberulous (1). Lemma apex obtuse; muticous, or awned (1); 1 -awned (1/1). Palea 1 length of lemma; 2 -veined. Palea keels scabrous. Apical sterile florets resembling fertile though underdeveloped. FLOWER Anthers 3. Ovary glabrous. FRUIT Caryopsis with adherent pericarp; ellipsoid. DISTRIBUTION Europe, or Africa (1), or Temperate Asia (1).
