Welcome to the Online Virtual Flora of Wisconsin

This site is a collaborative effort between the herbaria of the UW-Madison (WIS) and the UW-Steven's Point (UWSP), along with most of the other herbaria located in the state of Wisconsin. It contains information on each of the more than 2600 vascular plant species that occurs in Wisconsin, including photos, distribution maps, specimen records, and more.

Enter a genus, species, or common name to view the species description pages.
View detailed species descriptions, photos, interactive maps, and links to specimen records and additional information.

We’ve been making some changes!

You may have noticed some changes on the Online Flora of Wisconsin website lately!

Here are some of the changes we have made and/or are working on:

New layouts for the Taxon Profile Pages.
Changes to the way images are displayed.
Updates to the spatial module with new map layers and functionality.
Updating the photos with new higher resolution images.
Adding dichotomous keys from the ongoing work on the Flora of Wisconsin.
(See the “Keys” tab above for a list of families and genera with completed keys.)
Updating the county level maps.

This is all currently a work in progress, and we welcome your comments and constructive criticisms. Check out the site and let us know what you like, don’t like, or would like to see in the future! Also, we would like to add more photographs of the plants of Wisconsin to the website and replace some of the old low-resolution images. If you have photographs that would like to donate to the website, please let us know. Contact me at the email at the bottom of the page. Mary Ann Feist, Curator, Wisconsin State Herbarium.
