B. L. Davidson (2000) summarized evidence for taxonomic recognition of plants from populations in the extreme southern (El Dorado and Placer counties) and northern (Shasta County) portions of the range as distinct varieties. The southern populations have been recognized as Lewisia serrata and are distinguished by the combination of rounded to obtuse leaf apices, shorter stems (10–25 cm), longer pedicels (3–8 mm), and shorter petals (5–6 mm). The northern populations are distinguished by the combination of longer stems (30–60 cm) and scarcely glandular or eglandular margin teeth.
