Descriptions

Morphology General Habit
Annual; caespitose. Culms decumbent; 25-70 cm long. Leaf-sheath oral hairs ciliate. Leaf-sheath auricles falcate. Ligule an eciliate membrane. Leaf-blades 2-15 cm long; 2-4 mm wide. Leaf-blade surface pilose; sparsely hairy; hairy adaxially.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 1; single; oblong; bilateral; 4-10 cm long. Rhachis fragile at the nodes; villous on margins. Spikelet packing broadside to rhachis. Rhachis internodes oblong; falling with spikelet above. Spikelets solitary. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 7-20 mm long; falling entire; deciduous with accessory branch structures.
Fertile
Spikelets comprising 2 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 7-20 mm long; falling entire; deciduous with accessory branch structures.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes similar; shorter than spikelet. Lower glume oblong; 1 length of upper glume; coriaceous; much thinner on margins; 2-keeled; 5 -veined. Lower glume surface with tufts of hair along primary vein. Lower glume apex truncate; awned; 1 -awned. Lower glume awn 10-40 mm long. Upper glume oblong; 0.75 length of adjacent fertile lemma; coriaceous; with membranous margins; 2-keeled; 5 -veined. Upper glume lateral veins convergent at apex. Upper glume surface with tufts of hair along primary vein. Upper glume apex truncate; awned; 1 -awned. Upper glume awn 10-40 mm long.
Morphology Reproductive morphology Flowers Florets
Fertile lemma lanceolate; 10-13 mm long; coriaceous; keeled; 5 -veined. Lemma surface glabrous, or pubescent; hairy on veins; with tufts of hair on midvein; bearing 2-10 hair tufts in all. Lemma apex entire, or dentate; 2 -fid; acuminate; awned; 1 -awned. Principal lemma awn apical, or from a sinus; 20-50 mm long overall; limb scabrous. Palea keels scabrous. Apical sterile florets 1 in number; barren; linear; 1-2 mm long.
Morphology Reproductive morphology Flowers
Ovary with a fleshy appendage below style insertion; pubescent on apex.
Distribution
Europe: southwestern, southeastern, and eastern. Africa: north. Asia-temperate: Caucasus and western Asia.
