The University of Michigan Herbarium is home to some of the finest botanical collections in the world. The 1.7 million specimens of vascular plants, algae, bryophytes, fungi, and lichens combined with the expertise of the faculty-curators, students, and staff provide a world-class facility for teaching and research in systematic biology and biodiversity studies.
The goals of this Michigan Flora Website are to present, in a searchable and browsable form, the basic information about all vascular plants known to occur outside of cultivation in the state. This includes, unlike the published Michigan Flora, the spore bearing vascular plants (ferns, horsetails, club mosses, etc). Information available includes maps showing the distribution of all the species in the state, keys to all the families, genera, and species, brief discussions about the species, including habitats, nativity, date of first collection of aliens, and in some cases, notes helpful to identification beyond the features noted in the keys.
