Discussion

The distinction between Erythranthe latidens and E. inflatula sometimes seems arbitrary, perhaps because of gene exchange where they are sympatric in northwestern California. Erythranthe latidens in Oregon is known only from southern Harney County.

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.
