Discussion | Erythranthe norrisii is known only from the Kaweah River drainage; most populations are in Sequoia National Park in Tulare County. The species is characterized by its short-petiolate leaves with attenuate bases, very large corollas with red splotches at the base of each lobe and two white patches on the abaxial limb, and very short, purple-dotted calyces with rounded-thickened ribs and linear-oblong lobes incurved in fruit. The capsules often are slightly exserted. (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.
