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. Fruit: generally ovoid to fusiform, generally upcurved if elongate, generally +- fragile, loculicidal near tip (hard, indehiscent), chambers 1--2. Seed: many, generally < 1 mm, ovoid, +- yellow to dark brown.
Species In Genus: +- 100 species: North America, Chile, eastern Asia, southern Africa, New Zealand, Australia. Etymology: (Latin: little mime or comic actor, from face-like corolla of some species) Note: Limb width measured between most distant points across corolla face.
Species: Mimulus aurantiacusView Description 

Habit: Subshrub, shrub, glabrous to hairy. Stem: 10--150 cm; main leaf axils generally with small leaf clusters. Leaf: 10--88 mm; upper surface glabrous, lower generally sticky. Inflorescence: pedicel 3--30 mm. Flower: calyx 17--45 mm, not swollen at base, glabrous to hairy, lobes unequal, 2--11 mm, acute to acuminate; corolla persistent, +- yellow, orange, or red, tube-throat 25--57 mm; placentas parietal.
