Morphology General Habit
Annual; caespitose. Culms erect; (1-)2-2.5(-4) cm long. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 1-2 mm long. Leaf-blades 0.4-2.5 cm long; 1-2.5 mm wide. Leaf-blade surface scaberulous; rough adaxially. Leaf-blade margins scaberulous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; shorter than basal leaves; subtended by an inflated leaf-sheath; embraced at base by subtending leaf. Panicle spiciform; elliptic, or ovate; 3-5 cm long; 0.4-0.7 cm wide. Primary panicle branches accrescent to a central axis; with evident branchlets on axis. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; with a barren rhachilla extension. Spikelets elliptic, or ovate; laterally compressed; truncate; 3-3.8 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 1 fertile florets; with a barren rhachilla extension. Spikelets elliptic, or ovate; laterally compressed; truncate; 3-3.8 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; exceeding apex of florets. Lower glume elliptic; 3-3.8 mm long; 1 length of upper glume; membranous; much thinner on margins; 1-keeled; winged on keel; 3 -veined. Lower glume primary vein spinulose. Lower glume surface pubescent. Lower glume apex truncate; mucronate. Upper glume elliptic; 3-3.8 mm long; 3-4 length of adjacent fertile lemma; membranous; with hyaline margins; 1-keeled; wingless; 3 -veined. Upper glume primary vein spinulose. Upper glume surface pubescent. Upper glume apex truncate; mucronate (0.2-0.3mm).
Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; 0.8-1 mm long; membranous; without keel; 1 -veined. Lemma surface glabrous. Lemma apex obtuse. Palea 0.6-0.7 length of lemma.
Morphology Reproductive morphology Flowers
Lodicules 2; membranous. Anthers 2; 0.7-0.9 mm long. Ovary glabrous.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; ovoid; isodiametric; 0.9-1 mm long. Hilum punctiform.
Distribution
Europe: southwestern and southeastern. Asia-temperate: western Asia.
