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 norrisii is known only from the Kaweah River drainage; most populations are in Sequoia National Park in Tulare County. The species is characterized by its short-petiolate leaves with attenuate bases, very large corollas with red splotches at the base of each lobe and two white patches on the abaxial limb, and very short, purple-dotted calyces with rounded-thickened ribs and linear-oblong lobes incurved in fruit. The capsules often are slightly exserted.
