Discussion | 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.

The corollas of Erythranthe minor are shorter than those of typical E. tilingii, and the two species are allopatric. Corollas of E. tilingii rarely may be equally as short as those of E. minor but are produced in scattered localities on plants that are depauperate in other ways. The range of E. minor is primarily in Colorado apparently extending southward into the Wheeler Peak area of Taos County, New Mexico. Attribution of its range into the La Sal Mountains of east-central Utah has been based on misidentifications of E. guttata; the distinction between E. guttata and E. minor in Colorado also needs clarification. Mimulus luteus Linnaeus var. alpinus A. Gray (1863, the type from Colorado) is an illegitimate name for Erythranthe minor, preceded by M. luteus var. alpinus Lindley (1827).
