Culm genticulate at the basal nodes. Blades coriaceous, needle-like at the end, about 6 cm long by 1-1.5 mm wide; ligule about 0.2 mm long, upper margin and backside ciliate. Inflorescence a contracted panicle, about 8 cm long. Spikelets 1-flowered, about 2.5 mm long; glumes chartaceous; the lower about 1.2 mm long, lanceolate, irregularly toothed at the apex, nerveless; the upper lanceolate, 1-nerved, acute; lemma and palea the same texture with the glume; lemma ovate lanceolate, 1-nerved, boat-shaped, about 2 mm long; palea ovate 2-keeled, truncate at the apex. Fruit an utricle, about 1 mm long; embryo more than 1/2 the length of the utricle.
