Morphology General Habit
Perennial; caespitose; clumped loosely. Culms 60-80 cm long; 3-4 -noded. Leaf-sheaths glabrous on surface. Leaf-sheath auricles erect. Ligule an eciliate membrane; 0.4-0.6 mm long. Leaf-blades 10-15 cm long; 4-6 mm wide. Leaf-blade margins scabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; loose; 15-25 cm long. Primary panicle branches 2 -nate; 5-8(-15) cm long. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 4-5 fertile florets; with diminished florets at the apex. Spikelets oblong, or ovate; laterally compressed; 16-18 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 4-5 fertile florets; with diminished florets at the apex. Spikelets oblong, or ovate; laterally compressed; 16-18 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 1.5-2.5 mm long; 0.5-0.66 length of upper glume; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 3-3.5 mm long; 0.5 length of adjacent fertile lemma; chartaceous; without keels. Upper glume apex acuminate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; 6-7 mm long; chartaceous; without keel; 5 -veined. Lemma surface scabrous. Lemma apex emarginate; mucronate, or awned; 1 -awned. Principal lemma awn 6-8 mm long overall. Palea 2 -veined. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Anthers 3; 1.3-1.7 mm long. Ovary pubescent on apex.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp. Hilum linear.
Distribution
Asia-temperate: China.
