Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Mimulus lewisii (Lewis' monkeyflower, great purple monkeyflower) is a perennial plant in the family Phrymaceae. It is named in honor of Meriwether Lewis. Together with other species in Mimulus section Erythranthe, it serves as a model system for studying pollinator-based reproductive isolation.Mimulus lewisii is a perennial herb, with stem length ranging from 25-80 cm and individual leaves ranging from 20-70 mm. The vegetative tissue is covered with fine hairs. The flowers are medium in size, set on fairly long (30-70 mm) pedicels, and range in color from pale pink (generally found in the Sierra Nevada populations) to dark magenta (more common in the Cascade Range and Rocky Mountains populations), with a central pair of carotenoid-rich yellow nectar guides covered in trichomes on the lower lobe of the corolla. Occasional populations of white-flowered individuals (which do not express anthocyanin pigments in the corolla) are known.
