Discussion

Though usually appearing acaulescent in alpine and shore situations, plants of var. foliolosa frequently have one or two evident internodes in lower elevation habitats along stream systems. Specimens intermediate between this and var. sericea are not uncommon. Assignment of all specimens to one or the other of the varieties is not always possible. The Pan-Arctic Flora (http://panarcticflora.org/) treats var. foliolosa as Oxytropis deflexa subsp. dezhnevii (Jurtzev) Jurtzev.
