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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Erythranthe marmorata is recognized by its erect, taprooted habit and annual duration, villous-glandular vestiture, ovate-petiolate leaves, flowers from middle to distal nodes, long, narrow corolla tube-throat abruptly flaring into a broad limb, abaxial middle corolla lobe with a large red splotch, and fruiting calyces dark-spotted and sharply nodding. The species is known from foothills in Calaveras, Stanislaus, and Tuolumne counties in the Stanislaus River drainage and from Amador County in the Mokelumne River drainage. A collection from Fresno County appears to be somewhat disjunct from the main range, and the plants are more densely villous than characteristic elsewhere, but their identification as E. marmorata otherwise seems secure. Erythranthe marmorata (previously identified as Mimulus whipplei) had been considered extremely rare or even perhaps extinct. See G. L. Nesom (2013d) for citations of recent collections.
