| Cardamine purpurea Cham. & Schltdl. | |
| Publ. & Syn. | Cham. & Schltdl., Linnaea 1: 20 (1826). Described from St. Lawrence Island (Alaska). Syntypes?: (1, LE) "St.-Laurence Isl.", 1816, leg. Eschscholtz; (2, HAL-85360) "Ins St. Laurentii", leg. A. v. Ch[amisso]. |
| Notes | Carlsen, M.H. Jørgensen, Elven, and Petrovsky: The several Russian chromosome voucher specimens from Wrangel Island differ morphologically from the Alaskan and northwestern Canadian Cardamine purpurea in leaf shape and dissection. The enlarged rounded to obtuse angular apical lobe in the Alaskan plants is replaced by a smaller, sharply angular (often triangular) apical lobe and also the lateral lobes differ. However, the microsatellite data (Jørgensen et al. 2008) merged the Wrangel Island plants within a major cluster of Alaskan and Yukon Territory C. purpurea. |
