2n= 56 (8x). - Alaska, Canada (NW). - Bowden (1959, counted on the type, 1964); Löve (1980a, repeated in 1984b).

Geography: American Beringian: ALA CAN.

Notes: Elven and Murray: Bowden (1959) described Elymus innovatus subsp. velutinus as a taxon ploidally and morphologically different from E. innovatus s. str. He was followed by Löve and Löve (1976a) and Löve (1980a, 1984b) who accepted them as two species within Leymus. Scoggan (1978b) stated that subsp. velutinus was known from "Alaska; type from Mi 264, Richardson Highway, the only known locality". This east-central Alaskan locality was also the only one recorded by Hultén (1968b) and is not arctic. However, Bowden (1959) listed more localities, and Löve (1980a) and Barkworth (2007a) included localities in the Northwest Territories. We have surveyed the material from Alaska and the Yukon Territory (ALA) and do not find any consistent variation. This might mean that nearly all the American Beringian plants (except for the southernmost Yukon Territory) belong to subsp. velutinus, and that subsp. innovatus is non-Beringian.
