HABIT Annual. Culms geniculately ascending; 3-16 cm long. Ligule an eciliate membrane. INFLORESCENCE Inflorescence composed of racemes. Racemes single; unilateral; bearing few fertile spikelets; bearing 2-10 fertile spikelets on each. Rhachis angular. Spikelet packing broadside to rhachis; lax. Spikelets ascending; solitary. Fertile spikelets sessile. FERTILE SPIKELETS Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 6-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pilose. GLUMES Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 0.5 length of upper glume; hyaline; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute; mucronate. Upper glume lanceolate; 0.7-0.8 length of adjacent fertile lemma; hyaline; 1-keeled; 1 -veined. Upper glume apex acute; mucronate. FLORETS Fertile lemma oblong; membranous; keeled; 3 -veined. Lemma apex lobed; 2 -fid; incised 0.25 of lemma length; awned; 3 -awned. Principal lemma awn from a sinus; geniculate. Lateral lemma awns shorter than principal. Palea 0.7 length of lemma; 2 -veined. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped. FLOWER Lodicules 2; fleshy. Anthers 3. Stigmas 2. FRUIT Caryopsis with adherent pericarp; linear; isodiametric; biconvex; apex fleshy. Embryo 0.2 length of caryopsis. Hilum punctiform. DISTRIBUTION Tropical Asia.
