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. (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.
