Geography: Amphi-Beringian - North American (N): RFE ALA CAN.
Notes: Gillespie and Elven: Two races of Oxytropis maydelliana have been proposed: an amphi-Beringian subsp. maydelliana east to the Mackenzie River and a North American subsp. melanocephala from the Mackenzie eastwards. The main diagnostic differences reported for subsp. melanocephala vs. subsp. maydelliana is in the pubescence in the inflorescence (see, e.g., Porsild and Cody 1980). These characters did not hold when inspecting a larger Canadian material (CAN). Gillett et al. (2007) did not recognize races of O. maydelliana. We do not accept the subspecies.
