Festuca kolymensis

HABIT Perennial; caespitose. Culms 30–40 cm long. Leaf-sheaths open for most of their length; glabrous on surface. Ligule a ciliolate membrane; 0.5 mm long. Leaf-blades filiform; conduplicate; elliptic in section; 0.4–0.6 mm wide. Leaf-blade venation comprising 5 vascular bundles. Leaf-blade surface glabrous.

INFLORESCENCE Inflorescence a panicle. Peduncle scaberulous above.

Panicle open; dense; 3–5 cm long.

Spikelets solitary. Fertile spikelets pedicelled.

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

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 3–3.5 mm long; 0.75 length of upper glume; chartaceous; without keels; 1 -veined. Lower glume primary vein scabrous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 4–4.5 mm long; 0.7–0.8 length of adjacent fertile lemma; chartaceous; without keels; 3 -veined. Upper glume primary vein scabrous. Upper glume apex acute.

FLORETS Fertile lemma oblong; 5–6 mm long; chartaceous; light brown; shiny; without keel; 5 -veined. Lemma surface scabrous; rough above. Lemma margins scabrous. Lemma apex acute; awned; 1 -awned. Principal lemma awn 2–3 mm long overall. Palea 2 -veined. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2. Anthers 3; 3 mm long. Ovary glabrous.

FRUIT Caryopsis with adherent pericarp. Hilum linear.

DISTRIBUTION Asia-temperate: Siberia.
