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.
