Descriptions

Morphology General Habit
Annual; caespitose. Culms geniculately ascending; 25-35 cm long. Leaf-sheath oral hairs ciliate. Leaf-sheath auricles falcate. Ligule an eciliate membrane. Leaf-blades 2-6 cm long; 2.5-3 mm wide. Leaf-blade surface pilose. Leaf-blade margins ciliate.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes; deciduous as a whole. Racemes 1; single; obovate; bilateral; 3-6 cm long; bearing few fertile spikelets; bearing 2(-3) fertile spikelets on each. Rhachis tough. Spikelet packing broadside to rhachis. Spikelets solitary. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Basal sterile spikelets rudimentary; 3 in number. Apical sterile spikelets barren; 1-2 in number; 1-2 mm long. Spikelets comprising 2 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 10-11 mm long; falling entire; deciduous with accessory branch structures.
Sterile
Basal sterile spikelets rudimentary; 3 in number. Apical sterile spikelets barren; 1-2 in number; 1-2 mm long.
Fertile
Spikelets comprising 2 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 10-11 mm long; falling entire; deciduous with accessory branch structures.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes similar; shorter than spikelet. Lower glume elliptic; gibbous; 9-10 mm long; 1 length of upper glume; coriaceous; without keels; 7-9 -veined. Lower glume lateral veins unequally thickened; ribbed. Lower glume surface pubescent. Lower glume apex awned; 2-3 -awned. Lower glume awn 20-50 mm long. Upper glume elliptic; gibbous; 9-10 mm long; 0.9 length of adjacent fertile lemma; coriaceous; without keels; 7-9 -veined. Upper glume lateral veins unequally thickened; ribbed; parallel at apex. Upper glume surface pubescent. Upper glume awned; 2-3 -awned. Upper glume awn 20-50 mm long.
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblong; 10-11 mm long; coriaceous; without keel; 5 -veined. Lemma apex dentate; 2-4 -fid; awned; 2-4 -awned. Principal lemma awn 10-25 mm long overall. Palea 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2. Ovary pubescent on apex.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; hairy at apex. Disseminule comprising a inflorescence.
Distribution
Europe: southwestern, southeastern, and eastern. Africa: north. Asia-temperate: Soviet Middle Asia, Caucasus, and western Asia.
