Discussion

Clarkia jolonensis is known only from Monterey County, mainly in the Outer South Coast Ranges. It is scarcely distinguishable morphologically from C. bottae except for seed color, but attempts to produce hybrids have been unsuccessful. Although in describing C. jolonensis Parnell suggested that its range did not overlap with that of C. bottae, the ranges in fact overlap extensively in Monterey County.

Clarkia australis is found in the foothills of the central Sierra Nevada range, from Calaveras, Madera, Mariposa, and Tuolumne counties, and has been designated as rare by the California Native Plant Society.

Clarkia australis is morphologically very similar to C. virgata and, based on its more southern distribution, may be derived from it. They are most readily distinguished morphologically by the narrower leaves of C. australis.
