| Deschampsia sukatschewii subsp. orientalis (Hultén) Tzvelev | |
| Publ. & Syn. | Tzvelev, Fl. Arct. URSS 2: 84 (1964). - Deschampsia cespitosa subsp. orientalis Hultén, Fl. Kamtchatka 1: 109 (1927). Lectotype (LE): Russian Far East: southern Kamtchatka, Akhomten Bay, 275 m s.m., 13. Sept. 1920, leg. E. Hultén 1362 (Tzvelev 1976: 282). |
| Notes | As circumscribed here, subsp. orientalis includes a majority of the lowland plants in Chukotka, around the Bering Strait, and along the coasts of northern Alaska and at least northwestern Canada. Moreover, there is a report under this name of a diploid chromosome number from Churchill on Hudson Bay, Manitoba (Löve and Löve 1981a). Barkworth's (2007b) merger of subsp. orientalis and subsp. borealis may be justified, in which case the name subsp. orientalis has priority based on Hultén (1927). |
