Morphology General Habit
Perennial; caespitose; clumped loosely. Culms erect; 8-70 cm long. Culm-internodes smooth. Ligule an eciliate membrane; 5 mm long; acute. Leaf-blades filiform; involute; 2-20 cm long; 1 mm wide; glaucous. Leaf-blade margins scabrous. Leaf-blade apex attenuate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; loose; 3-24 cm long; 2-15 cm wide. Primary panicle branches spreading. Panicle branches scaberulous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 fertile florets; with a barren rhachilla extension. Spikelets lanceolate, or oblong; laterally compressed; 3-5 mm long; breaking up at maturity; disarticulating above glumes but not between florets. Rhachilla internodes definite; pubescent. Floret callus pilose.
Fertile
Spikelets comprising 2 fertile florets; with a barren rhachilla extension. Spikelets lanceolate, or oblong; laterally compressed; 3-5 mm long; breaking up at maturity; disarticulating above glumes but not between florets. Rhachilla internodes definite; pubescent. Floret callus pilose.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; reaching apex of florets; similar to fertile lemma in texture; shiny. Lower glume lanceolate; 1 length of upper glume; membranous; purple; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume elliptic; 1-1.1 length of adjacent fertile lemma; membranous; purple; 1-keeled; 3 -veined. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblong; 3-4 mm long; membranous; shiny; without keel; 4 -veined. Lemma apex dentate; 4 -fid; with outer lobes longer; truncate; awned; 1 -awned. Principal lemma awn dorsal; arising 0.5 way up back of lemma; straight; 1.5-3 mm long overall. Rhachilla extension 0.5-0.75 length of fertile floret; pilose.
Morphology Reproductive morphology Flowers
Lodicules 2; membranous. Anthers 3. Ovary glabrous.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp. Hilum punctiform.
Distribution
Europe: central, southwestern, and southeastern. Asia-temperate: Caucasus.
