Michigan Flora - University of Michigan Herbarium

The immediate goals of MICHIGAN FLORA ONLINE 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. Tabular material available for all species includes common name, synonyms linking the name to the published volumes of Michigan Flora, coefficient of conservatism, the coefficient of wetness and the wetness index, whether native or alien, and the physiognomy (annual, biennial, perennial; tree, shrub, vine, forb, grass, sedge, fern).
