Mimulus michiganensis B. S. Walters

Like M. glabratus, growing in marly springs, in cold streams through cedar swamps, on calcareous shores, and in associated ditches, usually relatively near the Great Lakes shores. The Michigan monkey-flower has been on the Federal (and hence the state) list of endangered species since 1990. Its total range, so far as known, is in the Straits of Mackinac and Grand Traverse regions of Michigan (about 20 sites altogether in Benzie, Leelanau, Emmet, Cheboygan, and Mackinac Cos., and Beaver Island). There has been much research on the life history, ecology, evolution, and distribution of this rare taxon, summarized in Posto & Prather (2003), which justifies recognition at species rank.
