* Spikelets 5-6 mm long, green or reddish with 5-9 florets, the lower one(s) fertile, the upper reduced. Glumes linear-laceolate, acuminate, 1-nerved, 5-6 mm long, slightly exceeding the lemmas. Lemmas oblong, 2-3 mm long, thinly membranous, conspicuously ciliate on the margins, sparsely hispidulous elsewhere, the apex shortly bilobed with an awn-point 0.5 mm long from the sinus; pales oblong-elliptic with 2 keels.
