Discussion | The range of Erythranthe eastwoodiae appears to be essentially contiguous with that of E. verbenacea in the Grand Canyon region, but there is no evidence of hybridization. Erythranthe eastwoodiae (as Mimulus eastwoodiae) is in the Center for Plant Conservation’s National Collection of Endangered Plants.

Erythranthe androsacea occurs primarily in the southern half of California but is scattered as far north as Lake and Modoc counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
