Notes: FNA3: "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."
