Capnoides P. Miller. Tribe: Corydaleae. Rock Harlequin.
The genus is monotypic, an herb, of n. North America. Recent studies have emphasized the distinction of Capnoides from Corydalis. Lidén considered it more closely related to Adlumia and Dicentra than to Corydalis (Lidén 1981, 1986; Lidén et al. 1997). Pérez-Gutiérrez et al. (2012, 2015) found Capnoides sempervirens to be basal to the “core Fumarieae”; the treatment of this species as part of Corydalis is no longer tenable.
