Discussion | Subspecies 3 (3 in the flora). Clarkia purpurea consists of a diverse assemblage of hexaploid populations and is almost certainly derived from multiple origins followed by hybridization and, perhaps, backcrossing to parental species. Three morphological forms are recognized as subspecies; intergrades are frequent. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Subspecies 2 (2 in the flora). Clarkia borealis is closely related, and possibly ancestral, to C. mildrediae. The two species can be distinguished most readily by the degree of curvature of the inflorescence and the petal color. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
