HABIT Perennial; caespitose. Rhizomes short; pachymorph. Culms erect; 500 cm long; 50 mm diam.; woody. Culm-internodes terete; hollow; smooth; distally glabrous. Culm-nodes glabrous. Lateral branches dendroid. Leaf-sheaths striately veined; smooth; hirsute. Leaf-sheath oral hairs ciliate. Ligule an eciliate membrane. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 5–9 cm long; 5–11 mm wide. Leaf-blade venation with distinct cross veins. Leaf-blade surface pilose; hairy abaxially. Leaf-blade margins scabrous. Leaf-blade apex attenuate.
INFLORESCENCE Inflorescence a panicle.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 5–7 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 20–25 mm long; breaking up at maturity; disarticulating below each fertile floret.
GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 9–9.5 mm long; chartaceous; 1-keeled; 5 -veined. Lower glume primary vein scaberulous. Lower glume surface smooth; glabrous. Lower glume apex acuminate. Upper glume elliptic; 12 mm long; chartaceous; 1-keeled; 7 -veined. Upper glume primary vein scaberulous. Upper glume lateral veins with cross-veins. Upper glume surface smooth; glabrous. Upper glume apex acuminate.
FLORETS Fertile lemma elliptic; 15 mm long; 5 mm wide; chartaceous; without keel; rounded except near apex. Lemma surface puberulous. Lemma margins ciliate; hairy above. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn 2 mm long overall. Palea elliptic; 9–10 mm long. Palea keels ciliolate. Palea apex acute. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Lodicules 3; 2 mm long; ciliate. Anthers 3; 5.5 mm long. Stigmas 2; plumose.
FRUIT Caryopsis with adherent pericarp; apex unappendaged.
DISTRIBUTION Asia-temperate: China.
