Morphology General Habit
Perennial; caespitose. Culms erect, or decumbent; 50-140 cm long. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 1.5-5 mm long. Leaf-blades 20-45 cm long; 2-10 mm wide; stiff; glaucous. Leaf-blade surface smooth; glabrous. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle contracted; linear, or oblong; 9-18 cm long. Primary panicle branches 1-3 cm long. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 7-9 fertile florets; with diminished florets at the apex. Spikelets oblong, or cuneate; laterally compressed; 8-10 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes scaberulous.
Fertile
Spikelets comprising 7-9 fertile florets; with diminished florets at the apex. Spikelets oblong, or cuneate; laterally compressed; 8-10 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes scaberulous.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 3.5-4 mm long; 0.8-0.9 length of upper glume; scarious; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 4-5 mm long; 0.6-0.8 length of adjacent fertile lemma; scarious; without keels; 3 -veined. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblong; 6 mm long; membranous; without keel; 5 -veined. Lemma surface scaberulous. Lemma apex acute; muticous. Palea 1 length of lemma; 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2; membranous. Anthers 3. Ovary glabrous.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; glabrous. Hilum linear.
Distribution
Asia-temperate: Soviet Middle Asia and western Asia.
