Phenology	Flowering May–Jun.	Flowering (Mar–)Apr–May.

Discussion	Erythranthe purpurea is restricted to the San Bernardino Mountains in San Bernardino County and is disjunct in the Sierra San Pedro Mártir in Baja California, Mexico. (Discussion copyrighted by Flora of North America; reprinted with permission.)	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.
