Information

A robust perennial with a stout horizontally creeping rhizome. Culms up to 180 cm. high, 6-9-noded, erect, stout, terete, striate, smooth, puberulous but finally glabrescent. Leaf-sheaths striate, keeled, truncate and barbate at the mouth, rather tight when young, later somewhat loose and slipping off the culm. Ligule minutely ciliolate along the upper edge. Leaf-laminae (10)12-20(25) x (1.5)2-3.5 (4) cm., oblong-lanceolate to narrowly elliptic-oblong, at the rounded base constricted into a pseudo-petiole of 0.5-1.7 cm. in length, apex acute to acuminate, puberulous to glabrescent on both surfaces, smooth or somewhat scaberulous on the midrib beneath. Panicle 20-35 x 8-20 cm., ovate or broadly ovate to elliptic in outline; the branches mostly verticillate, spreading or obliquely ascending, slender, somewhat rigid, unbranched, scaberulous. Spikelets 8-12 mm. long, 3-5-flowered, narrowly oblong, greenish. Glumes 5-5.5 mm. long, obtuse to subacute, scaberulous on the keel, asperous on the flanks. Lemmas 4.5-5 mm. long, decreasing in size towards the apex, obtuse to subacute, dorsally somewhat asperous. Stamens 3; anthers 2-3 mm. long. Caryopsis unknown.
