Morphology General Habit
Annual. Culms erect; 25-30 cm long. Leaf-sheaths pilose. Ligule an eciliate membrane. Leaf-blades 3-5 cm long; 1.5-2.5 mm wide. Leaf-blade surface pilose; densely hairy.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; 7 cm long; 6 cm wide. Primary panicle branches ascending; bearing 1-4 fertile spikelets on each lower branch. Panicle branches straight, or flexuous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 1 length of fertile spikelet.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 10-15 mm long; 5-6 mm wide; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 10-15 mm long; 5-6 mm wide; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 2-3.5 mm long; 0.75 length of upper glume; membranous; without keels; 3 -veined. Lower glume apex acute. Upper glume lanceolate; 4-4.5 mm long; 0.75-0.9 length of adjacent fertile lemma; membranous; without keels; 5-7 -veined. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma trullate; widest at 0.5-0.66 of its length from base; 5.5-6 mm long; 3-4 mm wide; chartaceous; without keel; 7-9 -veined. Lemma surface puberulous. Lemma apex entire; emarginate, or obtuse; muticous. Palea 1 length of lemma. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2; membranous. Anthers 3; 2.5 mm long. Ovary with a fleshy appendage above style insertion; pubescent on apex.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; ellipsoid; hairy at apex; apex fleshy. Hilum linear.
Distribution
Asia-temperate: western Asia.
