Festuca djimilensis
HABIT Perennial; caespitose; clumped loosely. Rhizomes elongated. Butt sheaths dark brown. Basal innovations extravaginal. Culms erect; 30–70 cm long. Leaf-sheaths tubular for much of their length; with 1 of their length closed; with infolded margins. Ligule an eciliate membrane; 0.5 mm long. Leaf-blades filiform; conduplicate; 30–60 cm long; 0.9–1 mm wide; stiff. Leaf-blade venation comprising 9 vascular bundles; with 7 inner ridges; with 9 subepidermal sclerenchyma strands; with subepidermal sclerenchyma attached to veins above; without layer of subepidermal sclerenchyma masking vein striation. Leaf-blade surface scabrous. Leaf-blade apex acute.
INFLORESCENCE Inflorescence a panicle.
Panicle open; effuse; nodding; 7–15 cm long. Panicle branches flexuous; scabrous.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 6–7 fertile florets; with diminished florets at the apex. Spikelets lanceolate, or oblong; laterally compressed; 9–11 mm long; breaking up at maturity; disarticulating below each fertile floret.
GLUMES Glumes persistent; dissimilar; shorter than spikelet. Lower glume oblong; 4 mm long; 0.7–0.8 length of upper glume; chartaceous; much thinner on margins; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume lanceolate; 4.5–5.5 mm long; 0.7–0.8 length of adjacent fertile lemma; chartaceous; with scarious margins; without keels; 3 -veined. Upper glume apex acuminate.
FLORETS Fertile lemma lanceolate; 6–7.3 mm long; chartaceous; mid-green, or mid-green and purple; without keel; 5 -veined. Lemma surface scabrous; rough above. Lemma apex acuminate; mucronate, or awned; 1 -awned. Principal lemma awn 0.5–1 mm long overall. Palea 1 length of lemma; 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Anthers 3; 3 mm long. Ovary pubescent on apex.
FRUIT Caryopsis with adherent pericarp; hairy at apex. Hilum linear; 1 length of caryopsis.
DISTRIBUTION Asia-temperate: Caucasus and western Asia.
NOTES Poeae. Fl Turk 1993.
