Discussion | Erythranthe geyeri has commonly been regarded as conspecific with E. glabrata (Kunth) G. L. Nesom (as Mimulus glabratus var. jamesii), but typical E. glabrata has a different chromosome number and distinct morphology and its range does not reach the United States. In Mexico, the two species are broadly sympatric without intermediates. An allozyme study of the M. glabratus complex (R. K. Vickery 1990) indicated that the Great Plains populations of E. geyeri are distinct from those in New Mexico and Mexico, corresponding to a difference in pedicel vestiture.

Yellow-flowered populations of Erythranthe cardinalis occur on Cedros Island, Baja California, and in the Siskiyou Mountains of Oregon (R. K. Vickery 1992). They have been documented also on Santa Cruz Island, California. Populations of Erythranthe cardinalis in King and Yakima counties, Washington, are introduced and naturalized.
