| Micranthes unalaschensis (Sternb.) Gornall & H. Ohba | |
| Publ. & Syn. | Saxifraga flabellifolia R. Br. ex Torr. & A. Gray, Fl. N. Amer. 1: 569 (1840). Described from Unalaska in the Aleutian Islands (Alaska). - Micranthes flabellifolia (R. Br. ex Torr. & A. Gray) Small, N. Amer. Fl. 22, 2: 143 (1905). |
| Notes | Zhmylev: Micranthes unalaschensis is a southern Beringian boreal species, distributed mainly in the Commander and Aleutian islands. It may occur also on the Bering Sea islands and on the coast of Chukchi Peninsula and Alaska see map by Hultén (1968a), from where transition forms to M. calycina (hybrids?; Siplivinsky 1976) are known. Murray and Elven: Micranthes unalaschensis is documented (ALA) to occur as rare in the Arctic in southwestern Alaska. Transitions towards M. calycina occur farther north. |
| Chromosomes | 24. - Siberia (N), Far East (N). - Several reports, numerous counts. A report of 2n = 52 from northwestern Alaska (Johnson and Packer 1968, for Saxifraga davurica subsp. grandipetala) is problematic. It should belong to this species as it is the only one of the group known from the area and rarely mistaken for anything else. |
