Morphology General Habit
Perennial; caespitose. Basal innovations extravaginal. Culms geniculately ascending; 25-65 cm long; 1-2 mm diam. Culm-internodes smooth; distally glabrous. Leaf-sheaths loose; longer than adjacent culm internode. Leaf-sheath auricles falcate; 1 mm long. Ligule an eciliate membrane; 0.5-1 mm long; lacerate. Leaf-blades 10-17 cm long; 3-4 mm wide. Leaf-blade venation comprising 13-15 vascular bundles. Leaf-blade margins scaberulous. Leaf-blade apex attenuate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle contracted; linear. Primary panicle branches appressed; 2 -nate; bearing 2-3 fertile spikelets on each lower branch. Panicle axis scabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 0.5-5 mm long; scabrous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising (3-)5 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 15 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2 mm long; eventually visible between lemmas; smooth.
Fertile
Spikelets comprising (3-)5 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 15 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2 mm long; eventually visible between lemmas; smooth.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; dissimilar; shorter than spikelet; similar to fertile lemma in texture. Lower glume linear; 6 mm long; 0.75-1 length of upper glume; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface asperulous; rough at apex. Lower glume apex acuminate. Upper glume lanceolate; 5 mm long; 0.66-1 length of adjacent fertile lemma; chartaceous; without keels; 3 -veined. Upper glume surface asperulous; rough at apex. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma lanceolate; 6-9 mm long; chartaceous; without keel; 5 -veined. Lemma lateral veins with distinct primaries but obscure intermediates. Lemma surface asperulous; rough on veins. Lemma apex acute; awned; 1 -awned. Principal lemma awn 10-16 mm long overall. Palea 1 length of lemma; 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2; 1 mm long; membranous. Anthers 3; 3 mm long. Ovary glabrous.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; 3 mm long. Hilum linear.
Distribution
Asia-temperate: China.
