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 pulsiferae is characterized by minutely stipitate-glandular vestiture (lacking villous hairs), elongate internodes, persistent basal leaves, small, palmately veined, cauline leaves with short, three-veined petioles and elliptic-oblong to ovate or oblanceolate blades, divergent-arcuate pedicels, and small, all yellow, weakly bilabiate corollas.
