INFLORESCENCE Inflorescence a panicle.
Panicle open; ovate; dense, or loose; 4–20 cm long. Panicle branches stiff; eglandular, or glandular.
Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong; 1–3 mm long; eglandular, or glandular.
FERTILE SPIKELETS Spikelets comprising 6–16(–40) fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 3–15 mm long; 1.3–2 mm wide; breaking up at maturity; rhachilla persistent; retaining paleas. Rhachilla internodes definite.
GLUMES Glumes deciduous; similar; shorter than spikelet. Lower glume ovate; 1–1.7 mm long; 1 length of upper glume; eglandular, or glandular (on keel); 1-keeled; 1–3 -veined. Lower glume apex acute. Upper glume ovate; 1–1.7 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; 1.5–2 mm long; chartaceous; yellow, or grey, or purple; glandular on veins (keel); keeled; 3 -veined. Lemma lateral veins distinct. Lemma apex obtuse. Palea keels scabrous. Apical sterile florets resembling fertile though underdeveloped.
