Welcome to the Friesner Herbarium

The Friesner Herbarium digital collection project is a multiyear effort to link label information from our Indiana specimens with images in a searchable electronic format.  Our goal is to increase access to, awareness of and use by all Indiana citizens of the valuable historical botanical information contained with the Friesner Herbarium.  Images of 20,000 specimens are available online now.

Visit the Indiana Plant Atlas (IPA) -- the IPA compiles and presents data on county-level occurrence of Indiana’s spontaneous flora – plants that grow outside of cultivation. Thousand of photos of live plants are available on the Atlas. Our master list of what grows in Indiana is from Yatskievych, Dolan, Moore, King and Kartesz Indiana Vascular Plants Catalog (in prep.) Nomenclature in the IPA is based on the Catalog.  For a plant to be included in the Catalog, its occurrence in Indiana must be documented by at least one herbarium specimen.
