Purple Monkeyflower (Erythranthe lewisii)
Description
Erythranthe 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, sometimes separated as Erythranthe erubescens G.L.Nesom) 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.[citation needed] Occasional populations of white-flowered individuals (which do not express anthocyanin pigments in the corolla) are known.
