Festuca cordubensis

HABIT Perennial; caespitose; clumped loosely. Butt sheaths persistent and investing base of culm; with compacted dead sheaths. Culms 30–60 cm long. Culm-internodes distally glabrous. Leaf-sheaths tubular for much of their length; without keel; glabrous on surface, or pubescent. Ligule an eciliate membrane; 0.3–0.7 mm long; truncate. Leaf-blades conduplicate; 13–25 cm long; 1.5–2.5 mm wide.

INFLORESCENCE Inflorescence a panicle. Peduncle smooth.

Panicle open; lanceolate; 23 cm long. Primary panicle branches ascending. Panicle branches scabrous.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 6–7 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 10–13 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pilose.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 4.5–5.5 mm long; 0.7–0.8 length of upper glume; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 6–7 mm long; 0.9 length of adjacent fertile lemma; chartaceous; without keels; 3 -veined. Upper glume apex acute.

FLORETS Fertile lemma lanceolate; 6.5–7.5 mm long; chartaceous; without keel; 5 -veined. Lemma surface pubescent. Lemma apex acute; awned; 1 -awned. Principal lemma awn 1.5 mm long overall. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Anthers 3; 3–4.2 mm long. Ovary glabrous.

DISTRIBUTION Europe: southwestern.
