Clarkia cylindrica
Clarkia affinis
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 affinis is known primarily from west-central California and the North Coast Ranges, and more scattered in the Sierra Nevada Foothills and Western Transverse Ranges.
Clarkia affinis is a hexaploid most closely related to C. purpurea; both have 2n = 52. Chromosome pairing in hybrids between them, as well as morphology, suggest that they have a tetraploid (2n = 34) genome in common. The two species are most readily distinguished by their immature capsules, which in C. affinis are slender, at least ten times longer than wide, beaked, and shallowly grooved, whereas those of C. purpurea are stout, not more than eight times longer than wide, not prominently beaked, and deeply grooved; the sepals of the former are generally reflexed together in fours whereas those of the latter are reflexed individually or in twos. Based on morphology and molecular data, the diploid genome probably came from C. cylindrica or a related species.
