Elymus uralensis

HABIT Perennial; caespitose. Rhizomes short. Culms 50–100 cm long. Culm-internodes distally pubescent. Leaf-sheaths glabrous on surface, or pubescent. Ligule an eciliate membrane. Leaf-blades 5–10 mm wide. Leaf-blade surface pubescent; sparsely hairy; hairy adaxially, or on both sides.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 1; single; bilateral; 8.5–17 cm long. Rhachis flattened. Spikelet packing broadside to rhachis. Rhachis internodes linear.

Spikelets solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 4–5 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 15 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes sparsely hairy.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 8–10 mm long; 1 length of upper glume; coriaceous; without keels; 5 -veined. Lower glume surface scabrous; rough on veins; glabrous, or pubescent; hairy on veins. Lower glume apex acute; awned; 1 -awned. Lower glume awn 3–7 mm long. Upper glume lanceolate; 8–10 mm long; 1 length of adjacent fertile lemma; coriaceous; without keels; 5 -veined. Upper glume surface scabrous; rough on veins; glabrous, or pubescent; hairy on veins. Upper glume apex acute; awned; 1 -awned. Upper glume awn 3–7 mm long.

FLORETS Fertile lemma oblong; 8–11 mm long; coriaceous; 5 -veined. Lemma surface puberulous. Lemma apex acute; awned; 1 -awned. Principal lemma awn 8–18 mm long overall. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2; membranous. Anthers 3; 2.5 mm long. Stigmas 2. Ovary pubescent on apex.

FRUIT Caryopsis with adherent pericarp.

DISTRIBUTION Europe: eastern. Asia-temperate: Siberia, Soviet Middle Asia, Caucasus, China, and Mongolia.
