Discussion

Erythranthe sierrae is endemic to the southern Sierra Nevada in Fresno, Kern, and Tulare counties. The species was previously treated as E. palmeri but can be distinguished by having leaf margins that are often toothed, pale pink corollas, and white stamens. Erythranthe palmeri has entire leaf margins that are never toothed, deep pink to purple corollas, and yellow stamens.
