Robert W. Freckmann Herbarium

Attention

Because of technology changes and personnel changes at UWSP and the Wisconsin State Herbarium, the database of plant species housed at this site was merged with the database from the OLD WisFlora website to create a new Flora of Wisconsin website at http://wisflora.herbarium.wisc.edu/. Currently we are encouraging all Wisplant viewers to begin using the Flora of Wisconsin website as soon as possible. Wisplants will remain operational through July 13th. After that date, all traffic to Wisplants will be redirected to the Flora of Wisconsin website.

Please direct any comments to wisconsin.state.herbarium@gmail.com.

Thank you.
