Discussion | Subspecies 3 (3 in the flora). Clarkia purpurea consists of a diverse assemblage of hexaploid populations and is almost certainly derived from multiple origins followed by hybridization and, perhaps, backcrossing to parental species. Three morphological forms are recognized as subspecies; intergrades are frequent. (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.
