HABIT Perennial. Rhizomes short; pachymorph. Culms 200–500 cm long; 6–25 mm diam.; woody. Culm-internodes terete; hollow; 15–28 cm long; ridged; distally pruinose. Lateral branches dendroid. Branch complement several. Culm-sheaths deciduous but leaving a persistent girdle; 10–18 cm long; chartaceous (above), or coriaceous (below); brown; distinctly mottled with last colour; pilose; with tawny hairs; without auricles; setose on shoulders; shoulders with 1–2 mm long hairs. Culm-sheath ligule 1 mm high; ciliolate. Culm-sheath blade linear, or lanceolate; reflexed; 5–10 cm long; glabrous on surface. Leaves 2–4 per branch. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs ciliate. Leaf-sheath auricles erect; 1–2 mm long. Ligule a ciliolate membrane; 1 mm long; truncate. Leaf-blade base cuneate; without a false petiole, or with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 4–10(–15) cm long; 4–15 mm wide. Leaf-blade venation indistinct; with 4–8 secondary veins. Leaf-blade surface glabrous.
INFLORESCENCE Inflorescence composed of racemes; comprising 5–8 fertile spikelets; subtended by a spatheole; embraced at base by subtending leaf.
Racemes 1; single.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 3–7 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 35–60 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 8–15 mm long; pilose.
GLUMES Glumes one the upper absent or obscure, or two; persistent; similar; shorter than spikelet. Lower glume lanceolate; 27–40 mm long; chartaceous; without keels. Upper glume lanceolate; 27–40 mm long; chartaceous; without keels.
FLORETS Fertile lemma lanceolate; 20–30 mm long; chartaceous; without keel. Lemma margins ciliate. Palea 15–20 mm long; 2-keeled. Palea apex dentate; 2 -fid; ciliate. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Lodicules 3. Anthers 3; 6–10 mm long; yellow. Stigmas 2; plumose. Ovary glabrous.
FRUIT Caryopsis with adherent pericarp; linear; sulcate on hilar side; 10–15 mm long; dark brown.
DISTRIBUTION Asia-temperate: China.
