Leaf sheaths purplish green, pubescent, outer margin ciliate; leaf blades narrowly lanceolate, 3–7 × 0.4–0.8 cm with the upper much longer than the lower, both surfaces but especially abaxial papillose-pilose, or subglabrous, margins scaberulous, base rounded, apex acute; ligule ca. 1.5 mm. Panicle open, 4–10 cm, eglandular; primary branches well spaced, smooth, slender, divaricate; pedicels longer than spikelets. Spikelets elliptic, 2–2.4 mm; florets similar; glumes equal to spikelet, herbaceous with broad scarious margins, slightly shining, prominently 5–9-veined, glabrous or rarely upper glume sparsely hirtellous, apex rounded but appearing subacute through incurling margins, lemmas pale creamy-brown, leathery, elliptic-oblong, weakly convex, 1.5–2 mm, glabrous or puberulous.
