Descriptions

Morphology General Habit
Annual; caespitose; clumped loosely. Culms erect; 40-100 cm long. Leaf-sheath oral hairs lacking. Leaf-sheath auricles falcate. Ligule an eciliate membrane. Leaf-blades flat, or involute; 10-20 cm long; 4-5 mm wide. Leaf-blade surface glabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes; not deciduous as a whole. Racemes 1; single; linear; bilateral; 7-13 cm long; bearing 7-15 fertile spikelets on each. Rhachis fragile at the nodes. Spikelet packing broadside to rhachis. Rhachis internodes oblong; falling with spikelet above. Spikelets solitary. Fertile spikelets sessile.
Sterile
Basal sterile spikelets rudimentary; 1-2 in number.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 8-13 mm long; falling entire; deciduous with accessory branch structures. Basal sterile spikelets rudimentary; 1-2 in number.
Fertile
Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 8-13 mm long; falling entire; deciduous with accessory branch structures.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes similar; shorter than spikelet. Lower glume oblong; 6-7 mm long; 1 length of upper glume; coriaceous; without keels; 6-7 -veined. Lower glume lateral veins thickened; ribbed; parallel at apex. Lower glume surface scabrous. Lower glume apex dentate; 2 -fid. Upper glume oblong; 6-7 mm long; 0.75 length of adjacent fertile lemma; coriaceous; without keels; 6-7 -veined. Upper glume lateral veins thickened; ribbed; parallel at apex. Upper glume surface scabrous. Upper glume apex dentate; 2 -fid.
Morphology Reproductive morphology Flowers Florets
Fertile lemma elliptic; 8-11 mm long; coriaceous; keeled; keeled above; 5 -veined. Lemma apex dentate; 2 -fid; awned, or awned only on distal spikelets; 1 -awned. Principal lemma awn from a sinus; 30-80 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 rhachis internode.
Distribution
Asia-temperate: western Asia.
