Discussion

Erythranthe filicaulis is known only for certain from Mariposa and Tuolumne counties. Kappler 1691 (UCLA) from Madera County also may be this species.

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.
