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.
