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.

Erythranthe parishii occurs in the southern Sierra Nevada (Kern and Tulare counties), mountain ranges of southern California (five counties), desert mountains (Inyo County), and in Clark and southern Nye counties, Nevada. It is the only annual species of sect. Erythranthe.
