Species: Mimulus primuloides

Primrose Monkeyflower is a small, perennial herb that forms mats of small rosette-like plants from a network of thin shallow-rooted rhizomes. The stems are up to 6 cm tall. The lance-shaped leaves are mostly entire-margined, lack petioles, and are 7-25 mm long. The foliage is covered with both stiff and soft hairs (it is sometimes glabrous), and is also often sticky. The flowers are solitary and located on the ends of stalks that are longer than the leafy stems. The yellow corollas are 1-2 cm long, two-lipped, and formed of petals united most of their length into a tube with flaring, notched lobes. The narrow calyx is 4-8 mm long and also formed of united segments.
