Discussion | Erythranthe washingtonensis is considered to be extirpated in Washington by the Washington Natural Heritage Program. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Erythranthe palmeri has been confused with other closely related species, including E. diffusa, E. discolor (pink form), E. rhodopetra, and E. sierrae. It was previously thought to be a widely distributed species because of this taxonomic confusion but now is regarded as endemic to the Transverse Range in the San Bernardino and San Gabriel mountains.
