About the Herbarium:
Herbarium Sheet

The University of Wisconsin—Milwaukee Peter J. Salamun Herbarium (UWM) is one of the largest in the state, with a total of approximately 66,000 accessioned specimens. The majority of the dried plant specimens are from Wisconsin, especially the southeastern portion of the state. Included is an extensive collection of the flora found at the University of Wisconsin-Milwaukee Field Station, a six square mile area of wetlands and mixed deciduous forests. UWM also has collections from other areas of the country and the world. These include the American Southwest (especially the Sonoran Desert), Australia, Northern Europe, and Alaska.

The UWM collection is of significant historical value. This is the result of the past efforts of professional botanists as well as private collections of plant enthusiasts that were willed to UWM. UWM houses specimens collected by Increase Lapham in the nineteenth century, the algae collection of J. Blum, the collection of fleshy fungi of F. Hainer, the extensive collection of liverworts and mosses by R. Hatcher, and numerous collections of Wisconsin and Southwest United States by P. Salamun. In recognition of Peter J. Salamun’s contributions over the years to the herbarium and the funding of a scholarship fund, the collection was recently renamed in his memory.

Why visit the UWM Herbarium?
UWM is invaluable to the university and the public as a historical collection and as a research and educational facility. It can be useful to anyone from the general public who is interested in a particular taxonomic group, needs to confirm a plant identification, or would like information such as plant species' range or habitat.
