Discussion

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.

Clarkia pulchella is the only North American species in the genus that does not occur in California; instead it is found throughout most of eastern Oregon and Washington, western Idaho, and northwestern Montana, to southern British Columbia, with disjunct occurrences in Bannock County in Idaho, Teton County in Wyoming, and Meade County in South Dakota. It was first discovered in 1806 by Meriwether Lewis during the Lewis and Clark expedition, and was the first species named in the new genus Clarkia.

Clarkia pulchella is an allopolyploid that combines morphological characteristics of sect. Myxocarpa (C. borealis and relatives), which includes two species with 2n = 10, and sect. Eucharidium (C. concinna and C. breweri) with 2n = 14. Molecular data support a relationship with sect. Eucharidium but at present show no direct association with sect. Myxocarpa.

Clarkia elegans Poiret is an illegitimate name that pertains here.
