HABIT Perennial. Culms 8–40 cm long. Ligule a ciliolate membrane.
INFLORESCENCE Inflorescence composed of racemes.
Racemes borne along a central axis; in a multilateral false spike; unilateral. Rhachis flattened.
Spikelets solitary. Fertile spikelets sessile.
FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 4–4.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
GLUMES Glumes persistent; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 0.5 length of upper glume; hyaline; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume surface without pits. Lower glume apex obtuse. Upper glume lanceolate; 1 length of adjacent fertile lemma; membranous; without keels; 1 -veined. Upper glume apex acute.
FLORETS Fertile lemma elliptic; coriaceous; without keel; wingless; 3 -veined. Lemma lateral veins obscure. Lemma surface unwrinkled; without grooves. Lemma apex dentate; 2 -fid; mucronate. Palea 1 length of lemma; coriaceous; 2 -veined.
FRUIT Caryopsis with adherent pericarp; ellipsoid.
