| Publ. & Syn. | Juz., Fl. URSS 10: 612 (1941). Type (LE): Russian Far East: South Chukotka, "in ditione fl. Anadyr", leg. V. Vassiljev. |
| Notes | The presence of tetraploids and decaploids in this morphologically uniform and easily recognized species is strange. The decaploids seem to be restricted to the Anyui Mountains, and someone should take a close look at the voucher specimens and compare them thoroughly with the tetraploids. Yurtsev: Potentilla stipularis var. groenlandica is a special form that occurs in isolated localities on Wrangel Island and in northeastern Greenland. It may well be a climatype. Elven and Murray: The occurrence of the same variety in eastern Greenland and Wrangel Island, and only there, throws some serious doubt on this variety as a taxon. We agree with Yurtsev that it is special but mainly in its range. |
