| Hierochloë odorata subsp. arctica (J. Presl) Tzvelev | |
| Publ. & Syn. | Tzvelev, Zlaki SSSR: 349 (1976). - Hierochloë arctica J. Presl in C. Presl, Reliq. Haenk. 1: 252 (1830). Lectotype (PR 25243): Canada: British Columbia, Vancouver Island, Nootka Sound, leg. Hänke (Weimarck 1971: 150). - Hierochloë hirta subsp. arctica (J. Presl) G. Weim., Bot. Not. 124: 150 (1971). - Anthoxanthum hirtum subsp. arcticum (J. Presl) G.C. Tucker, Harvard Pap. Bot. 1, 9: 66 (1996). |
| Notes | Greenland is added to Weimarck's (1971) treatment. We have confirmed a specimen (O), not seen by Weimarck, from southern Greenland. Allred and Barkworth (2007) synonymized Hierochloë arctica with Anthoxanthum hirtum. For reasons stated above, we do not follow that solution. |
| Chromosomes | (1) 56 (8x). - Europe (N), Russia (N), Siberia (N), Far East (N), Canada, U.S.A. - Numerous reports, more than 100 counts. (2) 70 (10x). - Canada. - Hedberg (1967); Weimarck (1971, 1973). (3) ca. 84 (12x). - U.S.A. - Weimarck (1971, 1973). Probably a stray high polyploid in an otherwise 2n = 56 population. |
