Notes: Korobkov (PAF proposal) synonymized Rhodiola arctica with R. rosea s. str. Rhodiola arctica (R. rosea subsp. arctica) occurs in the arctic and northern alpine parts of the range of R. rosea, mainly in northern Europe. High mountain plants of Fennoscandia are inseparable morphologically from the arctic plants. Transition to R. rosea s. str. is gradual. We agree that it probably is not appropriate to accept an arctic and high-alpine European race.
