Discussion

Clarkia lingulata is listed as endangered by the State of California, known from only a few populations in Merced River Canyon, Mariposa County. It is derived from C. biloba subsp. australis, from which it can be distinguished morphologically by its narrower, unlobed petals; the two taxa also differ in chromosome number, and form only highly sterile hybrids.

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.
