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.

Clarkia dudleyana is a rather widespread species in California, known primarily from the central and southern Sierra Nevada foothills, the Tehachapi Mountain area, the Transverse Ranges, and the Peninsular Ranges, ranging from Tuolumne to Riverside counties, sporadically in the north to Nevada County and in the south to San Diego County

Clarkia dudleyana is morphologically most similar to C. biloba and C. modesta, but molecular data suggest that the relationship is not close. On the basis of chloroplast DNA sequence, C. dudleyana and C. heterandra are closely related.
