Notes: Carlsen, M.H. Jørgensen, and Elven: In a PCO analysis of microsatellite data (Jørgensen et al. 2008), Cardamine digitata separated on two groups. Each group included both Asian and North American plants. One group included tetraploids and hexaploids, whereas no plants were counted in the second group. Comparison of vouchers has convinced us that both groups belong within one species morphologically.
