Erythranthe is a genus of flowering plants in the family Phrymaceae. Formerly known as Mimulus, this genus includes around 111 species of annual and perennial herbs that are native to North America, South America, and Australia. These plants are commonly called monkeyflowers due to their resemblance to a monkey’s face.

Taxonomic Information

Appearance

Erythranthe plants have simple, opposite leaves that are usually serrated or toothed. The flowers are bilaterally symmetrical and have two-lipped corollas that come in a wide range of colors, including pink, red, orange, yellow, purple, and white. The shape of the flowers varies depending on the species, but they generally resemble a monkey’s face, with two upper petals forming a hood and three lower petals forming a mouth.
