28 (4x). - Canada, U.S.A., Greenland. - Several reports for "latiglumis" and "violaceus".
The assignment of reports published for "latiglumis" is often uncertain as this name has been applied to different species in different regions, e.g., often to the alpine plants in Scandinavia (by us as E. alaskanus subsp. borealis).
Geography: North American (N): ALA CAN GRL.
Notes: Elven and Murray: Tzvelev treated subsp. violaceus and subsp. latiglumis as two races of Elymus violaceus. Campbell and Soreng in Soreng et al. (2003) merged them in a subsp. violaceus of E. trachycaulus. Barkworth et al. (2007) accepted E. violaceus as species and considered "latiglumis" a synonym for it.
