Morphology General Habit
Perennial. Rhizomes elongated. Culms 9-18 cm long. Culm-nodes glabrous. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 2-2.5 mm long; truncate. Leaf-blades flat, or involute; 3-5 cm long; 2 mm wide. Leaf-blade surface glabrous. Leaf-blade margins scaberulous. Leaf-blade apex acute.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; comprising 10 fertile spikelets. Panicle open; dense; 2.5 cm long; 1 cm wide; bearing few spikelets. Panicle branches pubescent in axils. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic, or cuneate; laterally compressed; truncate; 5 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic, or cuneate; laterally compressed; truncate; 5 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume elliptic; 5 mm long; 1 length of upper glume; membranous; much thinner above; purple; 1-keeled; 3 -veined. Lower glume apex acute. Upper glume elliptic; 5 mm long; 1.2 length of adjacent fertile lemma; membranous; much thinner above; purple; 1-keeled; 3 -veined. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets dissimilar; male; with palea; attached to and deciduous with the fertile. Lemma of lower sterile floret elliptic; 4 mm long; 1 length of fertile lemma; membranous; glabrous, or pubescent; bearing yellow hairs; lobed; 2 -fid; obtuse. Palea of lower sterile floret pubescent (at apex). Lemma of upper sterile floret oblong; 4 mm long; 1 length of lower sterile floret; membranous; pubescent; lobed; 2 -fid; awned. Awn of upper sterile floret 3 mm long. Fertile lemma elliptic, or oblong; 2.5 mm long; cartilaginous; without keel. Lemma surface pubescent; hairy above. Lemma margins convolute; covering most of palea. Lemma hairs yellow. Lemma apex obtuse, or acute. Palea 1 -veined; without keels.
Morphology Reproductive morphology Flowers
Lodicules 2. Anthers 2 (bisexual), or 3 (male); 1-1.25 mm long. Ovary glabrous.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp.
Distribution
Asia-temperate: China.
