Morphology General Habit
Perennial; caespitose. Rhizomes short. Culms geniculately ascending; 35-85 cm long. Culm-nodes glabrous, or pubescent. Leaf-sheath auricles falcate. Ligule an eciliate membrane. Leaf-blades convolute; 1.5-3 mm wide. Leaf-blade surface puberulous; hairy adaxially.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 1; single; bilateral; 5-10 cm long; bearing few fertile spikelets. Rhachis flattened; pubescent on margins. Spikelet packing broadside to rhachis. Spikelets solitary. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 6-8 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 8-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus 0.2-0.4 mm long; glabrous; obtuse.
Fertile
Spikelets comprising 6-8 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 8-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus 0.2-0.4 mm long; glabrous; obtuse.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet. Lower glume elliptic, or oblong; 6-10 mm long; 0.9 length of upper glume; coriaceous; without keels; 5-7 -veined. Lower glume lateral veins ribbed. Lower glume surface smooth, or scabrous. Lower glume apex entire, or with a unilateral tooth, or dentate; 1-2 -fid; acute; mucronate, or awned; 1 -awned. Lower glume awn 1-6 mm long. Upper glume elliptic, or oblong; 6-10 mm long; 0.75-0.9 length of adjacent fertile lemma; coriaceous; without keels; 5-7 -veined. Upper glume lateral veins ribbed. Upper glume surface smooth, or scabrous. Upper glume apex entire, or with a unilateral tooth, or dentate; 1-2 -fid; acute; mucronate, or awned; 1 -awned. Upper glume awn 1-6 mm long.
Morphology Reproductive morphology Flowers Florets
Fertile lemma lanceolate to oblong; 4-6 mm long; coriaceous; keeled; keeled above; 5 -veined. Lemma surface scabrous; rough above. Lemma margins eciliate, or ciliolate. Lemma apex acute; awned; 1 -awned. Principal lemma awn curved; reflexed; 15-35 mm long overall. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2; elliptic; membranous. Anthers 3. Stigmas 2. Ovary pubescent on apex.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp.
Distribution
Asia-temperate: Caucasus and western Asia.
