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 barbata previously has been placed in synonymy with E. montioides but differs from it in having each corolla lobe deeply notched and a consistently bearded palate. In E. montioides, each corolla lobe is entire or shallowly notched, and the palate is glabrous or sparsely bearded. Erythranthe barbata is most abundant in Tulare County but also occurs in immediately adjacent Inyo and Kern counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
