| Cardamine pensylvanica Muhl. ex Willd. | |
| Publ. & Syn. | Willd., Sp. Pl. 3, 1: 486 (1800). Described from Pennsylvania (U.S.A.). |
| Notes | Porsild and Cody (1980) mapped tentative occurrences of Cardamine pensylvanica in the Borderline Arctic on Hudson Bay. Occurrences of this species may be behind the report of C. parviflora from the northern parts of Canada (see Excluded taxa). Hultén (1968a: 513, map 3b) reported a locality in the Kotzebue area in western Alaska in his world map but this locality was not included in his Alaska map. Alaska is omitted. |
