Diplacus

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 (species with axile placentation and long pedicels), 46 placed into Diplacus (species with parietal placentation and sessile flowers), 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.
