| Elymus violaceus (Hornem.) Feilberg | |
| Publ. & Syn. | Agropyron violaceum var. latiglume Scribn. & J.G. Sm., U.S.D.A. Div. Agrostol. Rep. Agrostol. 4: 30 (1897). Lectotype (US-556692): U.S.A.: Montana, Gallatin Co., Lone Mountain, Aug. 1886, leg. F. Tweedy 1011 (Hitchcock and Chase 1951: 798). - Elymus violaceus subsp. latiglumis (Scribn. & J.G. Sm.) Tzvelev, Novosti Sist. Vyssh. Rast. 32: 181 (2000). |
| 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. |
| Chromosomes | 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). |
