Discussion

Plants of var. johannensis from south of James Bay, Ontario, have fasciculate leaves and relatively short fruits; the latter characteristic indicates a close relation­ship to var. chartacea. Some specimens appear to be tran­sitional to Oxytropis splendens. The Pan-Arctic Flora (http://panarcticflora.org/) treats var. johannensis as a synonym of O. terrae-novae.

Variety johannensis is in the Center for Plant Conservation’s National Collection of Endangered Plants.
