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 rhodopetra is endemic to the El Paso Mountains in Kern County. The species was treated previously as part of E. palmeri but is distinguished by having a wider limb (16–25 mm) than E. palmeri (8–15 mm) and pale pink flowers with a broad yellow palate and orifice. In contrast, E. palmeri has deep pink corollas with two yellow ridges on the palate. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
