Festuca pseudosclerophylla
HABIT Perennial; caespitose; clumped loosely. Rhizomes elongated. Butt sheaths glabrous. Culms geniculately ascending; 50–100 cm long. Culm-internodes smooth; distally glabrous. Lateral branches lacking. Leaf-sheath auricles falcate. Ligule an eciliate membrane; 0.5 mm long. Leaf-blades flat; 20–45 cm long; 5 mm wide; stiff. Leaf-blade surface scabrous; rough adaxially; glabrous. Leaf-blade margins scabrous. Leaf-blade apex attenuate.
INFLORESCENCE Inflorescence a panicle.
Panicle open; linear; 10–21 cm long; 1–1.5 cm wide. Primary panicle branches ascending; 2–4 cm long.
Spikelets solitary. Fertile spikelets pedicelled. Pedicels scabrous.
FERTILE SPIKELETS Spikelets comprising 5 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 10–12 mm long; breaking up at maturity; disarticulating below each fertile floret.
GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume oblong; 3.5–4.5 mm long; 0.75 length of upper glume; hyaline; pallid; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 4.5–5.5 mm long; 0.9 length of adjacent fertile lemma; hyaline; pallid; without keels; 3 -veined. Upper glume surface smooth, or asperulous; rough on veins. Upper glume apex acute.
FLORETS Fertile lemma elliptic; 5–6 mm long; membranous; without keel; 5 -veined. Lemma apex acute; awned; 1 -awned. Principal lemma awn apical, or subapical. Palea 2 -veined. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Lodicules 2. Anthers 3. Ovary glabrous.
FRUIT Caryopsis with adherent pericarp. Hilum linear.
DISTRIBUTION Asia-temperate: western Asia.
NOTES Poeae. Fl Iran 1995.
