Yellow monkeyflower in Detail.

Mimulus guttatus, commonly known as the common monkeyflower or yellow monkeyflower, is a flowering plant species native to western North America, from Alaska and British Columbia south to California and New Mexico. It is a member of the family Phrymaceae, which also includes other species of monkeyflowers.

The plant is typically found in moist habitats such as streambanks, seeps, and wet meadows, but it can also tolerate drier conditions. Mimulus guttatus produces bright yellow flowers with five petals that are arranged in a bilaterally symmetrical shape, giving them a distinct monkey face-like appearance, hence the common name "monkeyflower."

Yellow monkeyflower has been widely studied in the field of evolutionary biology due to its high genetic and morphological variability. It has also been used as a model organism for studies on plant ecology and genetics, as well as for understanding the genetic basis of adaptation and speciation.

Additionally, Mimulus guttatus has been used in traditional medicine by Native Americans for treating various ailments, such as skin conditions, sore throat, and eye infections. It has also been studied for its potential pharmacological properties, including its ability to lower blood pressure and its anti-inflammatory effects. Use caution if consuming.
