Discussion

Subspecies 2 (2 in the flora).

As defined by Davis, the subspecies of Clarkia cylindrica have distinct but partly overlapping geographical ranges; subsp. cylindrica mainly in the South Coast and Transverse Ranges to the Tehachapi Mountain area, and subsp. clavicarpa mainly in the central and southern Sierra Nevada Foothills to the Tehachapi Mountain area. More recent collections suggest more substantial geographical overlap. Morphological variation correlates with geographical distribution, with the most consistent difference in ovary and capsule shape. According to Davis, the taxa are moderately interfertile, less so for more distantly separated individuals.

Clarkia williamsonii occurs widely along the western slope of the Sierra Nevada from Nevada to Kern counties, and the Tehachapi Mountains barely to Los Angeles and Santa Barbara counties (one collection each). There are unverified reports from Riverside and Shasta counties.

Clarkia williamsonii is similar to C. speciosa and some populations of the hexaploid C. purpurea but can be distinguished from the former by petal color pattern and from both by having sepals that have distinctly free tips in bud, a trait most obvious in pressed specimens when the tips tend to spread apart.
