Culm sheaths deciduous, trapezoid, initially thinly white powdery, glabrous, asymmetrically arched, apex slanted along outer side; auricles very small to inconspicuous, oral setae few; ligule 1–1.5 mm, irregularly dentate; blade deciduous, erect, narrowly triangular, base nearly as wide as sheath apex, abaxially with scattered, stiff, dull brown hairs, adaxially scabrous, apex acuminate. Leaves 5–26 per ultimate branch; leaf blade abaxially pale glaucous, adaxially bright green, linear, 1.6–16 × 0.3–1.6 cm, abaxially densely pubescent, adaxially glabrous. Pseudospikelets solitary or several clustered at nodes of flowering branches, linear to linear-lanceolate, 3–6 cm; prophylls ca. 3.5 mm, 2-keeled, keels ciliolate; gemmiferous bracts usually 1 or 2, ovate to narrowly ovate, 4–7.5 mm, glabrous, 9–13-veined, apex obtuse or acute; florets (3–)5–13, middle ones fertile; rachilla segments flat, 4–4.5 mm, glabrous.
