Mimulus is a plant genus in the family Phrymaceae, which was traditionally placed in family Scrophulariaceae. The genus now contains only seven species, two native to eastern North America and the other five native to Asia, Australia, Africa, or Madagascar. In the past, about 150 species were placed in this genus, most of which have since been assigned to other genera, the majority to genus Erythranthe. Mimulus species prefer wet or moist areas and are not drought resistant.

Taxonomy
Prior to the 2012 restructuring, it had long been recognized that there were two large groups of species within the genus Mimulus as it was traditionally defined, with the largest group of species in western North America, and a second group with center of diversity in Australia. 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.
The removal of Mimulus from family Scrophulariaceae has been supported by studies of chloroplast DNA first published in the mid-1990s. Multiple studies of chloroplast DNA and two regions of nuclear rDNA suggest that the genera Phryma, Berendtiella, Hemichaena, Leucocarpus, Microcarpeae, Peplidium, Glossostigma, and Elacholoma are all derived from within Mimulus and would need to be rearranged.
