Discussion

R. K. Vickery (1992) noted that yellow-flowered morphs of Erythranthe verbenacea occur in a population at Vasey’s Paradise in the Grand Canyon (Coconino County), 32 miles downstream from Lees Ferry.

Populations of Erythranthe verbenacea in the Oak Creek Canyon area in southern Coconino County, Arizona, have leaves with a narrow, lateral, undulating, purple stripe across the mid lamina. The coloration is retained even in dried specimens.

In Utah, Erythranthe verbenacea is known only from the Zion Canyon area.

Molecular (P. M. Beardsley et al. 2003) and morphological (G. L. Nesom 2014b) data indicate that Erythranthe verbenacea is sister to E. eastwoodiae.

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).
