HABIT Perennial. Stolons present. Culms 5-15 cm long. Ligule a fringe of hairs. INFLORESCENCE Inflorescence composed of racemes; embraced at base by subtending leaf. Racemes single; unilateral. Rhachis angular. Spikelets solitary. Fertile spikelets sessile. FERTILE SPIKELETS Spikelets comprising 1-2 basal sterile florets; 2-3 fertile florets; with diminished florets at the apex. Spikelets cuneate; dorsally compressed; 7-9 mm long; breaking up at maturity; disarticulating above glumes but not between florets. Floret callus elongated; pubescent; pungent. GLUMES Glumes persistent; reaching apex of florets; thinner than fertile lemma; gaping. Lower glume lanceolate; 0.5 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume lanceolate; membranous; without keels; 3 -veined. Upper glume apex acuminate. FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret elliptic; coriaceous; 7-9 -veined; awned. Fertile lemma elliptic; coriaceous; without keel; 7-9 -veined. Lemma surface pubescent. Lemma apex lobed; 3 -fid; incised 0.4 of lemma length; awned; 1 -awned. Principal lemma awn dorsal. Palea 2 -veined. Palea keels ciliolate. Apical sterile florets 1 in number; barren; elliptic. Apical sterile lemmas awned. FLOWER Anthers 2-3. FRUIT Caryopsis with free soft pericarp; obovoid. Embryo 0.75 length of caryopsis. Hilum punctiform. DISTRIBUTION Tropical Asia.
