Discussion

Earlier segregation of Erythranthe moniliformis as distinct from E. moschata (for example, G. L. Nesom 2012g) emphasized a primarily erect habit and tendency toward sessile to subsessile and more densely arranged cauline leaves in E. moniliformis versus a decumbent to procumbent habit and consistently petiolate leaves on longer internodes in E. moschata. Discontinuities in morphology, geography, and ecology were not confirmed in later study by Nesom (2017). Rhizomes with small, tuberlike swellings can be observed over the whole moschata/moniliformis range, and there apparently are no consistent distinctions in vestiture and corolla size.

Mimulus acutidens Reiche (1911), a later homonym of M. acutidens Greene, pertains here.

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.
