Koeleria skrjabinii

HABIT Perennial; culms solitary. Rhizomes short. Culms erect; 25–60 cm long. Culm-internodes distally pilose. Leaf-sheaths pubescent. Ligule an eciliate membrane; 0.2–0.7 mm long; pubescent on abaxial surface. Leaf-blades convolute; 1.5–3.5 mm wide; stiff; glaucous. Leaf-blade surface scabrous; rough adaxially; glabrous.

INFLORESCENCE Inflorescence a panicle. Peduncle pubescent above.

Panicle spiciform; linear; loose; 3.5–9 cm long. Panicle axis pubescent. Panicle branches pubescent.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 2–4 fertile florets; with a barren rhachilla extension, or with diminished florets at the apex. Spikelets obovate; laterally compressed; 6–7.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.

GLUMES Glumes persistent; similar; reaching apex of florets; similar to fertile lemma in texture; shiny; gaping. Lower glume lanceolate; 4–5 mm long; 0.7–0.8 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scabrous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume oblong; 5–6.5 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume primary vein scabrous. Upper glume apex acute.

FLORETS Fertile lemma oblong; 5.4–6.5 mm long; membranous; shiny; keeled. Lemma surface scabrous. Lemma apex acute. Palea gaping; 0.9 length of lemma. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2; membranous. Anthers 3; 2.5–3.5 mm long. Ovary glabrous.

FRUIT Caryopsis with adherent pericarp.

DISTRIBUTION Asia-temperate: Siberia.
