HABIT Annual; caespitose. Glands wart-like (on keel). Culms erect, or geniculately ascending; 10–90 cm long. Ligule a fringe of hairs. Leaf-blades 5–15 cm long; 2–8 mm wide. Leaf-blade margins glandular, or eglandular.
INFLORESCENCE Inflorescence a panicle.
Panicle open, or contracted; ovate; dense, or loose; 4–30 cm long. Panicle branches stiff; glandular.
Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong; glandular.
FERTILE SPIKELETS Spikelets comprising 5–60 fertile florets; with diminished florets at the apex. Spikelets oblong, or ovate; laterally compressed; 3–20 mm long; 2–4 mm wide; breaking up at maturity; rhachilla persistent; retaining paleas; tough throughout, or fragile above; with the distal florets falling as a whole.
GLUMES Glumes deciduous; similar; shorter than spikelet. Lower glume ovate; 1.5–2.2 mm long; 1 length of upper glume; eglandular, or glandular (on keel); 1-keeled; 1–3 -veined. Lower glume apex acute. Upper glume ovate; 1.5–2.2 mm long; 0.7–0.8 length of adjacent fertile lemma; eglandular, or glandular; 1-keeled; 1–3 -veined. Upper glume apex acute.
FLORETS Fertile lemma ovate, or orbicular; (1.3–)2–2.8 mm long; chartaceous; yellow, or grey; glandular on veins (keel); keeled; 3 -veined. Lemma lateral veins distinct. Lemma apex emarginate, or obtuse. Palea keels scabrous. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Anthers 3; 0.3 mm long.
FRUIT Caryopsis with adherent pericarp; orbicular; 0.5(–0.7) mm long; dark brown, or red.
