Mimulus (icon) is a diverse plant

Plant

Plants are living organisms belonging to the kingdom Plantae. Precise definitions of the kingdom vary, but as the term is used here, plants include familiar organisms such as trees, flowers, herbs, bushes, grasses, vines, ferns, mosses, and green algae. The group is also called green plants or...

In biology, a species is one of the basic units of biological classification and a taxonomic rank. A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is adequate, more precise or differing measures are...

Family (biology)

In biological classification, family is* a taxonomic rank. Other well-known ranks are life, domain, kingdom, phylum, class, order, genus, and species, with family fitting between order and genus. As for the other well-known ranks, there is the option of an immediately lower rank, indicated by the...

 Phrymaceae

Phrymaceae

Phrymaceae , also known as the Lopseed family, is a small plant family in the order Lamiales. It now consists of about 190 species, distributed worldwide but with the majority in western North America and Australia .Previously, this family was monotypic with the genus Phryma, and limited in...

. The genus has traditionally been placed in Scrophulariaceae

Scrophulariaceae

Scrophulariaceae, the figwort family, are a family of flowering plants. The plants are annual or perennial herbs with flowers with bilateral or rarely radial symmetry. Members of the Scrophulariaceae have a cosmopolitan distribution, with the majority found in temperate areas, including...

. The removal of Mimulus from that family has been supported by studies of chloroplast

Chloroplast

Chloroplasts are organelles found in plant cells and other eukaryotic organisms that conduct photosynthesis. Chloroplasts capture light energy to conserve free energy in the form of ATP and reduce NADP to NADPH through a complex set of processes called photosynthesis.Chloroplasts are green...

Phryma

Phryma, or lopseed, is a perennial herb. The genus is native to eastern North America and Asia , and consists of either one or two species, depending on whether the American and Asian species are considered separate or not.The plant stands about 0.3 to 1.0 meters tall, and the...

, Berendtiella, Hemichaena, Leucocarpus, Microcarpeae, Peplidium, Glossostigma, and Elacholoma are all derived from within Mimulus and would need to be rearranged.

It is recognized that there are two large groups of Mimulus species, with the largest group of species in western North America
