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.

Subspecies 4 (4 in the flora).

Clarkia gracilis is a tetraploid derived from C. amoena and an unknown, presumably extinct, species related to C. arcuata and C. lassenensis. Clarkia gracilis is readily distinguished from C. amoena by the axis of the inflorescence in bud, which is not recurved in C. amoena; it is distinguished from C. arcuata and C. lassenensis by its four rather than eight-grooved ovary.
