Morphology General Habit
Perennial; caespitose. Rhizomes short; pachymorph. Culms erect; 700-1500 cm long; 60-80 mm diam.; woody; without nodal roots, or rooting from lower nodes. Culm-internodes terete; thick-walled; 26-34 cm long; distally mealy. Culm-nodes flush with internodes. Lateral branches dendroid. Branch complement many; with 3 branches dominant. Culm-sheaths tardily deciduous, or deciduous; 20-26 cm long; 1.5 times as long as wide; coriaceous; glabrous, or pilose; without auricles. Culm-sheath ligule 2 mm high; dentate. Culm-sheath blade ovate; as wide as sheath at base; erect; glabrous on surface; acuminate. Leaf-sheaths glabrous on surface; outer margin hairy. Leaf-sheath auricles absent. Ligule an eciliate membrane; 1 mm long; truncate. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 14-17 cm long; 8-16 mm wide. Leaf-blade venation with 10-12 secondary veins; with distinct cross veins. Leaf-blade surface pilose; hairy abaxially. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Synflorescence bractiferous; clustered at the nodes; in untidy tufts; with spathaceous subtending bracts; with axillary buds at base of spikelet; prophyllate below lateral spikelets; leafless between clusters. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 3-4 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; 8-16 mm long; 3-5 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes suppressed between florets.
Fertile
Spikelets comprising 3-4 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; 8-16 mm long; 3-5 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes suppressed between florets.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes one the lower absent or obscure, or two; persistent; similar; shorter than spikelet. Lower glume ovate; 5-7 mm long; chartaceous; without keels. Lower glume surface glabrous. Lower glume margins ciliate. Lower glume apex acute; mucronate. Upper glume ovate; 5-7 mm long; chartaceous; without keels. Upper glume surface glabrous. Upper glume margins ciliate. Upper glume apex acute; mucronate.
Morphology Reproductive morphology Flowers Florets
Fertile florets increasing in size upwards. Fertile lemma ovate; 7-13 mm long; 4-7 mm wide; chartaceous; without keel. Lemma apex acuminate; mucronate. Palea 6-14 mm long; chartaceous; 2-keeled but the uppermost without keels.
Morphology Reproductive morphology Flowers
Lodicules absent. Anthers 6; 4-6 mm long. Filaments 20 mm long. Stigmas 1.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp.
Distribution
Asia-temperate: China.
