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.

The relative constancy of Erythranthe pardalis in morphology suggests that genetic influence from other species is slight. It is recognized by its annual duration and relatively delicate habit, ovate to depressed-ovate leaves toothed mostly on the distal margins, small flowers produced from all nodes (proximal to distal), dark-spotted calyces, and stipitate-glandular cauline and foliar vestiture. While the corolla limbs are distinctly expanded, the tubes are only slightly exserted from the calyx, and flowers apparently are plesiogamous. The epithet pardalis alludes to the dark-spotted calyx.

Plants of Erythranthe pardalis occur primarily on serpentine rocks and soils but also grow on copper tailings at mine sites. The species is known from Amador, Calaveras, El Dorado, Placer, Tehama, and Tuolumne counties. The plants in Tehama County, geographically and ecologically disjunct from the main range, were recorded as growing in basalt crevices.
