Erythranthe, the monkey-flowers and musk-flowers, is a diverse plant genus with more than 120 members in the family Phrymaceae. Erythranthe was originally described as a separate genus, then generally regarded as a section within the genus Mimulus, and recently returned to generic rank. Mimulus sect. Diplacus was segregated from Mimulus as a separate genus at the same time. Mimulus remains as a small genus of eastern North America and the Southern Hemisphere. Molecular data show Erythranthe and Diplacus to be distinct evolutionary lines that are distinct from Mimulus as strictly defined, although this nomenclature is controversial.
Diplacus is a plant genus in the family Phrymaceae, which was traditionally placed in family Scrophulariaceae. In the 2012 restructuring of Mimulus by Barker, et al., based largely upon DNA evidence, seven species were left in Mimulus, 111 placed into Erythranthe, 46 placed into Diplacus, two placed in Uvedalia, and one each placed in Elacholoma, Mimetanthe, and Thyridia. Diplacus used to be a separate genus from Mimulus, but it was merged into Mimulus no later than 1905, until the 2012 restructuring. Dry and rocky areas are preferred.
