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.) |
Clarkia imbricata, known from only one small area of Sonoma County, is designated as rare by the California Native Plant Society, and is in the Center for Plant Conservation’s National Collection of Endangered Plants; it is a relict of a lineage with 2n = 16 that presumably contributed a genome to the tetraploid species C. davyi and the South American C. tenella. Morphologically, Clarkia imbricata is most similar to C. speciosa, C. williamsonii, and some populations of C. purpurea. Clarkia imbricata can be distinguished from C. speciosa by the color pattern of the petals and from C. williamsonii and populations of C. purpurea with similar flower size and color pattern by its broader, ascending, overlapping leaves.
