Elymus is a genus of perennial plants with approximately 150 species[5] in the grass family, related to rye, wheat, and other widely grown cereal grains.[6]

Elymus is a cosmopolitan genus, represented by species across all continents of the world.[7] Common names include couch grass, wildrye and wheatgrass.[8][9][10][11]

Many species once considered members of Elymus are now regarded as better suited to other genera: Agropyron, Anthosachne, Brachypodium, Cenchrus, Crithopsis, Heteranthelium, Jouvea, Kengyilia, Leymus, Psathyrostachys, Stenostachys, Taeniatherum, Thinopyrum etc.[12]
