Description

Genus Elymus

Plants perennial , usually tufted , usually without, rarely with, rhizomes. Culms usually erect . Leaf sheath of cauline leaves split almost to base ; auricles present or absent; leaf blade flat or rolled. Spike erect to nodding . Spikelets 1 or 2(4) per node, sessile, rarely very shortly pedicellate , appressed to rachis, clearly laterally compressed , usually all similar, with 210 or more florets ; rachis tough. Glumes opposite or side-by-side, linear-lanceolate to lanceolate-ovate, firmly membranous to leathery, 19(11) -veined, not keeled , apex obtuse to shortly awned ; veins ± raised. Lemma lanceolate-oblong, rounded abaxially, 5-veined, ± pubescent , apex obtuse or acute to awned, rarely toothed ; veins connivent at apex; awn erect or reflexed . Palea shorter than or equaling lemma, apex retuse , subrounded, or acute. Caryopsis usually adherent to lemma and palea. x = 7.

About 170 species:temperate regions of both hemispheres, mainly in Asia; 88 species (62 endemic) in China.

The genus Roegneria should be referred to Elymus because of their many common characters, e.g. , plants usually tufted; spikelets usually all similar, 1 per node; lemma lanceolate-oblong, rounded abaxially, 5-veined, veins connivent at apex.[1]
