Corydalis scouleri
Corydalis aqua-gelidae
Corydalis scouleri is restricted to cool, wet habitats from northwestern Oregon northward to Vancouver Island. It is most easily distinguished from Corydalis caseana by the usually highly developed crests and absence of wings on its outer petals. The stigma is essentially triangular (versus rectangular in C. caseana), and the capsule shape (typically obovoid) is rarely approached in C. caseana.

Because of morphologic intergradation with Corydalis caseana subsp. cusickii, G. B. Ownbey (pers. comm.) does not consider Corydalis aqua-gelidae a distinct species; he believes that it probably should be treated as a subspecies of C. caseana.
