HABIT Perennial. Culms woody. Culm-internodes terete. Lateral branches dendroid. Branch complement three. Leaves 1–3 per branch. Leaf-sheaths 2.5–3 cm long. Leaf-sheath oral hairs ciliate; 1.5–3.3 mm long. Ligule an eciliate membrane; 1 mm long; pubescent on abaxial surface; truncate, or obtuse. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.1–0.2 cm long. Leaf-blades lanceolate; 2.5–8 cm long; 3.5–7 mm wide. Leaf-blade venation with 6 secondary veins; with distinct cross veins. Leaf-blade surface glabrous. Leaf-blade margins scaberulous.

INFLORESCENCE Inflorescence composed of racemes; embraced at base by subtending leaf.

Racemes 1; single; bearing 3–5 fertile spikelets on each.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels 8–15 mm long; glabrous.

FERTILE SPIKELETS Spikelets comprising 4–6 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 20–30 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 4–5 mm long; pubescent. Floret callus pilose. Floret callus hairs 0.8 mm long.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 4–7 mm long; chartaceous; without keels; 3 -veined. Lower glume apex acuminate. Upper glume lanceolate; 7–10 mm long; chartaceous; without keels; 5–7 -veined. Upper glume apex acuminate.

FLORETS Fertile lemma lanceolate, or ovate; 10 mm long; chartaceous; without keel; 9 -veined. Lemma lateral veins with cross-veins. Lemma margins pubescent. Lemma apex attenuate. Palea 8 mm long. Palea keels ciliate; adorned above. Palea apex dentate; 2 -fid. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 3; 2 mm long; veined; ciliate. Anthers 3; 5 mm long; brown. Stigmas 2. Ovary glabrous.

FRUIT Caryopsis with adherent pericarp.

DISTRIBUTION Asia-temperate: China.
