Mimulus (play /ˈmɪmjuːləs/)[1] is a diverse plant genus, the monkey-flowers and musk-flowers. The about 150 species are currently placed in the family Phrymaceae. The genus has traditionally been placed in Scrophulariaceae. The removal of Mimulus from that family has been supported by studies of chloroplast DNA first published in the mid-1990s[citation needed]. Multiple studies of chloroplast DNA and two regions of nuclear rDNA[2] suggest that the genera Phryma, Berendtiella, Hemichaena, Leucocarpus, Microcarpeae, Peplidium, Glossostigma, and Elacholoma are all derived from within Mimulus and would need to be rearranged.
It is recognized that there are two large groups of Mimulus species, with the largest group of species in western North America, and a second group with center of diversity in Australia. A few species also extend into eastern North America, eastern Asia and southern Africa. This enlarged group is a part of the newly redefined Phrymaceae.

Mimulus is the remedy for known fears. Whenever you are frightened or anxious about something, and you can say what that 'something' is, then Mimulus is the remedy to take.
Mimulus fears are those of every day: fear of public speaking, of the dark, of aggressive dogs, of illness and pain. Phobias can also be Mimulus fears if the cause of the fear - whether spiders, birds or open spaces - can be named. Rock Rose might be preferred where the phobia causes real terror. Where the fear is vague and there is general anxiety and apprehension without a specific named cause, there Aspen might be a better choice.
Mimulus is used as a type or personality remedy for those of us who tend generally to be nervous, timid and shy. We might blush easily or stammer, and will usually avoid social occasions and any event where we will be in the limelight.
Mimulus brings out the quiet courage and strength that lies hidden in all of us, so that we can face the everyday trials of life without fear.

Dr Bach's description

edbach2.jpgFear of worldly things, illness, pain, accidents, poverty, of dark, of being alone, of misfortune. The fears of everyday life. These people quietly and secretly bear their dread, they do not freely speak of it to others.
