Discussion | Lewisia leeana is known only from northwestern California and southwesternmost Oregon, and a disjunct population in Fresno County, California. As discussed by B. Mathew (1989b), Lewisia ×whiteae Purdy (California) is a natural, constantly recurring hybrid between L. leeana and L. cotyledon. In their narrowly spatulate leaves, the hybrids resemble L. columbiana out of range (cf. L. T. Dempster 1993); the flowers are reportedly more deeply colored.

Of conservation concern. Lewisia congdonii is found only in Mariposa County, California. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
