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.

Erythranthe carsonensis is restricted to the Carson Valley, Eagle Valley, and Washoe Valley region of Nevada and adjacent California, with one known disjunct occurrence about 58 km to the north in Nevada. The species was previously included in the broader concept of E. montioides but can be distinguished by its much branched and compact habit, linear to spatulate leaves with clasping bases, calyx with glabrous margins, and larger corolla with one large red spot in the center. Erythranthe carsonensis has been impacted by agriculture, urbanization, and other anthropogenic changes.
