Morphology General Habit
Perennial; caespitose. Butt sheaths persistent and investing base of culm; with fibrous dead sheaths. Culms robust; 50-250 cm long. Ligule an eciliate membrane; 2.5-10 mm long. Leaf-blades flat, or involute; 20-45 cm long; 4-10 mm wide. Leaf-blade surface glabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; dense, or loose; 15-50 cm long; 10-35 cm wide. Primary panicle branches whorled at most nodes. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 5-6 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.3 mm long; pubescent; obtuse.
Fertile
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 5-6 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.3 mm long; pubescent; obtuse.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume elliptic; 4-4.5 mm long; 0.7-0.8 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume elliptic; 5-6 mm long; membranous; without keels; 3 -veined. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma elliptic; subterete; 4.8-5.7 mm long; coriaceous; without keel. Lemma surface pilose. Lemma margins convolute; covering most of palea. Lemma apex dentate; 2 -fid; with lobes 0.5-1.3 mm long; awned; 1 -awned. Principal lemma awn straight, or geniculate; 6-12 mm long overall; with a straight or slightly twisted column. Palea 2 -veined; without keels.
Morphology Reproductive morphology Flowers
Anthers 3. Stigmas 2. Ovary glabrous.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp. Hilum linear.
Distribution
Europe: eastern. Asia-temperate: Siberia, Soviet Middle Asia, western Asia, China, and Mongolia. Asia-tropical: India.
