Discussion		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.)
