glabrous, 4-20 cm long, 2-8 mm wide; sheath keeled, glabrous; ligule a ring of white hairs, 0.6-0.8 mm
long. Inflorescence of racemose racemes, racemes few to many, rachis flattened, puberulent, ca. 0.5 mm
wide; pedicel 1.5-2 mm long, bearing long stiff hairs, ca. 0.3 mm long, usually purplish; lower glume
minute, surrounding callus; upper glume slightly shorter than spikelet; lower palea wanting; upper
lemma pale, minutely rugose, ca. 2 mm long, with a hispidulous awn of ca. 0.5 mm long or less; anther
ca. 1.1 mm long.India, Sri Lanka, Myanmar, Indochina, Malesia and China. Taiwan, very common and limited to the
