Morphology General Habit
Perennial; caespitose; clumped densely. Culms 15-20 cm long; 1 -noded. Leaf-sheaths smooth. Leaf-sheath auricles erect. Ligule a ciliolate membrane; 0.4-0.6 mm long; truncate. Leaf-blades flat, or involute; 5-8 cm long; 1 mm wide. Leaf-blade margins scaberulous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; loose; 5-7 cm long. Primary panicle branches 1 -nate; 2-3 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; 8-10 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; 8-10 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; 2-3 mm long; 0.66-0.75 length of upper glume; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface smooth. Lower glume apex acute. Upper glume lanceolate; 3-4 mm long; 0.66 length of adjacent fertile lemma; chartaceous; without keels. Upper glume surface smooth. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; 5-6 mm long; chartaceous; purple; without keel; 5 -veined. Lemma surface puberulous, or pubescent. Lemma apex acute; mucronate. Principal lemma awn 2-3 mm long overall. Palea 2 -veined. Palea keels scabrous. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Anthers 3; 2-2.2 mm long. Ovary glabrous.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp. Hilum linear.
Distribution
Asia-temperate: China.
