Discussion
Erythranthe montioides has been previously treated as a highly polymorphic species with a relatively broad geographic range but is now recognized as narrowly endemic to Fresno and north-central Tulare counties. The following species were segregated from E. montioides: E. barbata, E. calcicola, E. carsonensis, and E. discolor.
