Irregular blue-violet flower, occasionally pink or white, 1 inch across. The upper lip is divided into 2 erect lobes and the lower lip has 3 rounded lobes. At the base of the middle lobe are 2 pale yellow to white spots. A whorl of sepals about 1 inch long with 5 long teeth form a tube behind the flower. The flowers arise on longish stalks from the leaf axils. One plant may have many flowers.
Leaves and stem:
Leaves are 2 to 4 inches long, ½ to 1 inch wide, with fine widely spaced teeth, tapering to a point at the tip, the rounded leaf base clasping the stem. Leaves and the square stem are both hairless. Leaf attachment is opposite.
This one is easy to ID, as there is nothing else like it in Minnesota, though a similar species with stalked leaves is native a bit farther east. Mimulus is one of the species that was formerly in the Scrophulariaceae (Figwort) family and is now in Phrymaceae (Lopseed). There are 2 varieties of M. ringens in North America; var. ringens found in Minnesota.
