Discussion | Erythranthe shevockii is known only from the southernmost Sierra Nevada in Kern County. It (as Mimulus shevockii) is in the Center for Plant Conservation’s National Collection of Endangered Plants. (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.) |
