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 diffusa has been included previously in E. palmeri but can be distinguished morphologically by glabrous margins on the calyx and pubescence on the distal end of the style. It occurs in Orange, Riverside, and San Diego counties as well as close to the California border in Baja California. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
