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 cinnabarina is similar to typical E. cardinalis in its spreading anther thecae, relatively short-exserted corolla tube, and its reflexing corolla lobes but distinct in its generally larger leaves with reduced vestiture, fewer flowers, larger calyx and corolla, apically caudate calyx lobes, and its separate geographical range.

Erythranthe cinnabarina occurs in Cochise County (Chiricahua Mountains), Graham County (Pinaleño Mountains), and Pima County (Santa Catalina Mountains). Erythranthe verbenacea, with which it sometimes has been confused, occurs at lower elevations (350–2600 m) and ranges over most of the state (Apache, Cochise, Coconino, Gila, Graham, La Paz, Maricopa, Mohave, Pima, Pinal, Santa Cruz, and Yavapai counties). Erythranthe cinnabarina apparently occurs alone (without E. verbenacea) in the Pinaleño Mountains and in the Chiricahua Mountains, but both species have been abundantly documented in the Santa Catalina Mountains, where they sometimes closely co-occur in areas of elevational overlap (for example, at Marshall Gulch, about 2500 m; at Bear Wallow Campground, about 2600 m).
