The MSU Herbarium :
The MSU Herbarium was founded in 1863 with the donation of a large collection of plants from Michigan and the eastern U.S. Today, we remain focused on plant and fungal diversity from Michigan, but the collection is also rich in plants from Mexico and southeast Asia, and lichens from the Caribbean and the subantarctic region. With over half a million specimens, the MSU Herbarium is among the 50 largest herbaria in the United States.
