Clarkia cylindrica
Clarkia xantiana
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.

Subspecies 2 (2 in the flora).
Originally placed in the group now delimited as subsect. Phaeostoma by H. Lewis and M. E. Lewis (1955), Clarkia xantiana was treated as a monotypic subsect. Xantianae within sect. Phaeostoma by K. E. Holsinger (1985), based mainly on its unusual 2-lobed petals with a tooth in the sinus. Molecular data (R. A. Levin et al. 2004) placed C. xantiana close to C. bottae, and both of them close to but not within sect. Phaeostoma. Both species share the chromosome number 2n = 18 with C. jolonensis.
