A highly variable plant, taking many forms, it is a species complex in that there is room to treat some of its forms as different species by some definitions. Mimulus guttatus is 10 to 80 cm tall with disproportionately large, 20 to 40 mm long, tubular flowers. The perennial form spreads with stolons or rhizomes. The stem may be erect or recumbent. In the latter form, roots may develop at leaf nodes. Sometimes dwarfed, it may be hairless or have some hairs. Leaves are opposite, round to oval, usually coarsely and irregularly toothed or lobed. The bright yellow flowers are born on a raceme, most often with five or more flowers. The calyx has five lobes that are much shorter than the flower. Each flower has bilateral symmetry and has two lips. The upper lip usually has two lobs; the lower, three. The lower lip may have one large to many small red to reddish brown spots. The opening to the flower is hairy
