HABIT Annual. Culms erect; 13–25 cm long. Ligule an eciliate membrane.
INFLORESCENCE Inflorescence a panicle.
Panicle open. Primary panicle branches whorled at most nodes; sterile at lowest node.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 3–6 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 2–5.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite; pubescent. Floret callus pubescent.
GLUMES Glumes persistent; shorter than spikelet. Lower glume lanceolate; 1.1 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface without pits. Lower glume apex acute. Upper glume ovate; 0.75 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume apex acute.
FLORETS Fertile lemma elliptic; lanceolate in profile; membranous; much thinner above; without keel; wingless; 5 -veined. Lemma surface unwrinkled; without grooves. Lemma apex lobed; 2 -fid; incised 0.2 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus. Palea 0.66 length of lemma. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Anthers 2. Ovary glabrous.
DISTRIBUTION Temperate Asia.
