Discussion

Erythranthe washingtonensis is considered to be extirpated in Washington by the Washington Natural Heritage Program.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

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.
