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 chinatiensis is similar to E. parvula in its prostrate habit, five-lobed calyces, and fimbriate corolla lobes. It differs from the latter in its nearly glabrous leaves and strongly reflexed abaxial corolla lip. Erythranthe chinatiensis is known only from Presidio County but should be expected to occur also in adjacent Chihuahua, Mexico.
