Discussion | Erythranthe dentata is distinctive and rarely misidentified. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
