HABIT Perennial; caespitose. Rhizomes short; pachymorph. Culms erect; pendulous at the tip; 2000 cm long; 100–150 mm diam.; woody; without nodal roots, or rooting from lower nodes. Culm-internodes terete; hollow; 35–46 cm long; distally mealy. Lateral branches dendroid. Branch complement many; with 1 branch dominant. Culm-sheaths deciduous; 30–40 cm long; coriaceous; pilose; without auricles. Culm-sheath ligule 3 mm high; dentate. Culm-sheath blade ovate; erect; 10–18 cm long; pubescent; acuminate. Leaves 8–10 per branch. Leaf-sheaths glabrous on surface; outer margin hairy. Leaf-sheath oral hairs setose; deciduous; 5–7 mm long. Leaf-sheath auricles falcate. Ligule an eciliate membrane; 1.5–2 mm long. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 18–25 cm long; 30–42 mm wide. Leaf-blade venation with 16–27 secondary veins. Leaf-blade surface glabrous; hairless except near base. Leaf-blade apex acuminate.

INFLORESCENCE Synflorescence bractiferous; clustered at the nodes; in globose clusters; 1–1.5 cm long; (2–)4–6.5 cm between clusters; with glumaceous subtending bracts; bracts 10–13 mm long; with axillary buds at base of spikelet; prophyllate below lateral spikelets; leafless between clusters.

Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 4 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; 10–13 mm long; 3–4 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes suppressed between florets.

GLUMES Glumes one the lower absent or obscure; persistent; shorter than spikelet. Upper glume ovate; 8–10 mm long; chartaceous; without keels. Upper glume apex acute; mucronate.

FLORETS Fertile florets increasing in size upwards. Fertile lemma ovate; 10–12 mm long; 5–6 mm wide; chartaceous; without keel. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn 1 mm long overall. Palea 7–9 mm long; chartaceous; 2-keeled but the uppermost without keels. Palea apex acuminate.

FLOWER Lodicules absent. Anthers 6; yellow, or purple. Stigmas 1.

FRUIT Caryopsis with adherent pericarp.

DISTRIBUTION Asia-temperate: China.
