Discussion
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.
Selected References
