Culms apically pendulous, ca. 2–2.5 m tall, 1–1.5 cm in diameter, wall thick or solid; internodes terete, 18–34 cm long, initially sparsely white pubescent, later glabrous; nodes prominent; sheath scars conspicuous. Branches several to many, one dominant branch nearly equal to the main culm in size, along with several slender subequal branches. Culm leaves tardily deciduous, shorter than internodes, 6–8 cm long, 3.5–6 cm wide at base, leathery, thin and brittle, yellow-green initially then becoming yellow before falling off; sheaths densely covered by dark brown bristles abaxially, margin glabrous, apex truncate; auricles persistent, nearly elliptical to narrowly falcate, hard, brown, 1.5–2 mm wide, oral setae absent; ligules ca. 1 mm tall, apex denticulate; blades erect, ovate-triangular, apex acuminate, cordate at base, 4–6.5 cm long, glabrous. Foliage leaves 6–8 per ultimate branch; leaf sheaths abaxial and margin white ciliate. Pseudopetioles 1–2 mm long; outer ligules glabrous, ca. 0.5 mm tall; inner ligules lobed, shorter than 1 mm; auricles narrow, orange-yellow, spreading with a few radiated and caducous oral setae; leaf blades long lanceolate, 18–22 × 1.1–1.3 cm, secondary veins 4–6 pairs, adaxial surface white hirsute, abaxial surface pubescent, margins serrulate.</p><p>Inflorescence iterauctant, with clusters of 1–3 (– 15) fertile pseudospikelets per node; internodes 4–15 cm long, covered with white hair. Pseudospikelets ovate-lanceolate, top and edge purple-green, 20–28 × 2–5 mm; 3–5 florets in each pseudospikelet with the terminal floret sterile; rachilla internodes 0.5–3 mm long, usually distinct and disarticulating with florets, falling separately. Glumes 2 or 3, ovate, 2–4.5 mm long, glabrous, veined. Fertile lemma lanceolate, thinly leathery, green, with top and edge purple, 6–15 mm long, glabrous, apex mucronate. Palea longer than or subequal to lemma, membranous, 2 - keeled, apex obtuse, keels and margins with long white cilia, apex margins pubescent. Lodicules 3, 2–3 mm long, membranous, margin with long cilia. Stamens 6, yellow, 5–6 mm long, filaments free. Pistil 1, style 1–1.4 cm long; stigmas 1 or 2, purple, plumose; ovary ovate.
