Elymus pendulinus

HABIT Perennial; caespitose; clumped loosely. Culms 70–110 cm long. Ligule an eciliate membrane. Leaf-blades 6–10 mm wide; flaccid. Leaf-blade surface scabrous; rough on both sides; glabrous.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 1; single; drooping; bilateral; 15–22 cm long. Rhachis flattened; puberulous on surface. Spikelet packing broadside to rhachis. Rhachis internodes linear.

Spikelets solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 5–6 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 13–20 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 6–9 mm long; 1 length of upper glume; coriaceous; without keels; 5 -veined. Lower glume surface scabrous. Lower glume apex setaceously attenuate. Upper glume lanceolate; 6–9 mm long; 0.75–0.9 length of adjacent fertile lemma; coriaceous; without keels; 5 -veined. Upper glume surface scabrous. Upper glume apex setaceously attenuate.

FLORETS Fertile lemma lanceolate; 8–10 mm long; coriaceous; 5 -veined. Lemma surface pubescent; hairy above. Lemma margins ciliate; hairy above. Lemma apex acute; awned; 1 -awned. Principal lemma awn 15–23 mm long overall. Palea 1 length of lemma. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.

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

FRUIT Caryopsis with adherent pericarp.

DISTRIBUTION Asia-temperate: Siberia, Soviet far east, China, and Mongolia.
