Genus: MimulusView DescriptionDichotomous Key

Habit: Glabrous to hairy. Stem: generally erect. Leaf: opposite, generally +- sessile, generally toothed or entire, generally green or +- red. Inflorescence: raceme, bracted, or flowers generally 2 per axil. Flower: occasionally cleistogamous; calyx generally green, lobes 5, generally << tube, generally unequal; corolla generally deciduous, white to red, maroon, purple, gold, or yellow, lower lip base occasionally swollen, +- closing mouth, tube-throat floor generally with 2 longitudinal folds; anther sacs spreading; placentas 2, axile or parietal; stigma lobes generally flat, generally included.
