Morphology General Habit
Perennial; caespitose; clumped loosely. Rhizomes short. Basal innovations extravaginal. Culms erect; 25-30 cm long. Culm-internodes terete. Lateral branches lacking. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 2-5 mm long; entire, or lacerate; truncate, or obtuse. Leaf-blades 3-5 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; 5-10 cm long. Panicle branches terete. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2-5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 5-7 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes smooth. Floret callus woolly.
Fertile
Spikelets comprising 2-5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 5-7 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes smooth. Floret callus woolly.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 0.8-0.9 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 0.8-0.9 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; 3-4.5 mm long; membranous; keeled; 5 -veined. Lemma midvein ciliate. Lemma margins ciliate. Lemma apex acute. Palea keels ciliate; adorned below. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2; membranous. Anthers 3; 2-2.4 mm long.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp. Hilum punctiform.
Vegetative Multiplication
Vegetative proliferation absent, or occurs.
Distribution
Europe: central, southeastern, and eastern.
