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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
