Morphology General Habit
Perennial; caespitose. Rhizomes short. Culms erect; 6-14 cm long. Ligule an eciliate membrane. Leaf-blades 2-7 cm long; 1-3 mm wide. Leaf-blade surface smooth. Leaf-blade margins scaberulous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; comprising 8-16 fertile spikelets. Panicle open; obovate; effuse; 4-5 cm long; 4-5 cm wide; bearing few spikelets. Primary panicle branches spreading; branching divaricately. Spikelets pendulous; solitary. Fertile spikelets pedicelled. Pedicels filiform.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; 4-6 mm long; 4-6 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes obscured by lemmas.
Fertile
Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; 4-6 mm long; 4-6 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes obscured by lemmas.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet. Lower glume orbicular; 2.5-3 mm long; 0.8-1 length of upper glume; membranous; much thinner on margins; purple; without keels; 3-5 -veined. Lower glume apex obtuse. Upper glume orbicular; 2.5-3 mm long; 0.6-0.9 length of adjacent fertile lemma; membranous; with hyaline margins; purple; without keels; 3-5 -veined. Upper glume apex obtuse.
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblate; auriculate at base; gibbous; 4 mm long; membranous; much thinner on margins; purple and yellow; bordered with last colour; keeled; lightly keeled; keeled below; 7-9 -veined. Lemma surface glabrous. Lemma apex obtuse. Palea oblong; 0.8-0.9 length of lemma; 2 -veined. Palea keels winged; narrowly winged; eciliate. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2. Anthers 3. Ovary glabrous.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp. Hilum punctiform.
Distribution
Asia-temperate: Caucasus and western Asia.
