Discussion | Erythranthe erubescens was long identified as E. lewisii but is distinct in its light pink corollas (versus mostly magenta-rose to purplish in E. lewisii), more broadly cylindric calyx tube [14–19 × 6–8 mm versus 12–15(–17) × 9–12 mm], and its geographic range in the Sierra Nevada of California (versus widespread from southern Alaska south to northwestern California, northern Utah, eastern Nevada, and northern Colorado in E. lewisii). The two are genetically isolated and phylogenetically distinct (see summary of evidence in G. L. Nesom 2014b). In California, Erythranthe erubescens ranges from Modoc, Plumas, and Tehama counties south to Fresno County; in Nevada, it is known only from Washoe County and Carson City.

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.) |
