HABIT Annual. Culms decumbent; 8–21 cm long. Ligule an eciliate membrane.

INFLORESCENCE Inflorescence a panicle.

Panicle open. Primary panicle branches whorled at most nodes.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 2–5 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 3–4.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite.

GLUMES Glumes persistent; shorter than spikelet. Lower glume elliptic; 0.8 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface scabrous; without pits. Lower glume apex acute. Upper glume elliptic; 0.8 length of adjacent fertile lemma; membranous; with hyaline margins; 1-keeled; 3 -veined. Upper glume surface scabrous. Upper glume apex acute.

FLORETS Fertile lemma elliptic; membranous; keeled; wingless; 3 -veined. Lemma midvein scaberulous. Lemma surface scaberulous; unwrinkled; without grooves; pilose; hairy between veins. Lemma apex acute; muticous, or mucronate. Palea 1 length of lemma. Palea keels ciliate. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2; membranous; with a small lateral lobe; acute. Anthers 3. Stigmas 2.

FRUIT Caryopsis with adherent pericarp; fusiform. Embryo 0.1 length of caryopsis. Hilum punctiform.

DISTRIBUTION Temperate Asia.
