Culm-nodes swollen; with distinct supra-nodal ridge. Lateral branches dendroid. Culm-sheaths chartaceous; green and yellow, or purple; striped; glabrous, or pubescent; with tawny hairs; hairy on margins; auriculate; setose on shoulders; shoulders with curved hairs. Culm-sheath ligule 2–3 mm high; purple; ciliate. Culm-sheath blade triangular; erect, or reflexed; wrinkled. Leaves cauline; 1–2 per branch. Leaf-sheath oral hairs scanty; erect. Leaf-sheath auricles absent. Ligule a ciliolate membrane. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 8–14 cm long; 12–18 mm wide.

INFLORESCENCE Synflorescence bractiferous; fasciculate; with spathaceous subtending bracts; without axillary buds at base of spikelet; with ultimate bract subtending a compact bracteolate fascicle of spikelets (1–2 spikelets); prophyllate below lateral spikelets.

Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 4–5 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; laterally compressed; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes one the lower absent or obscure, or two; persistent; shorter than spikelet. Upper glume oblong; chartaceous; without keels. Upper glume surface puberulous. Upper glume apex setaceously attenuate.

FLORETS Basal sterile florets barren; with palea. Lemma of lower sterile floret similar to fertile lemma. Fertile lemma lanceolate; 12–14 mm long; chartaceous; keeled. Lemma surface pubescent. Lemma apex setaceously attenuate. Palea chartaceous. Palea surface pubescent. Palea apex dentate; 2 -fid.

FLOWER Lodicules 3; oblanceolate; ciliate. Anthers 3; 6 mm long.

DISTRIBUTION Asia-temperate: China.
