Welcome to ARIZ, the University of Arizona Herbarium
With over 400,000 specimens, ARIZ is the world's largest collection of plants from Arizona and Sonora, Mexico.
These collections support a rich diversity of research projects by herbarium staff and university researchers. We also serve the general public, private organizations, and government agencies of all levels as a provider of information on the plants of Arizona and the Sonoran Desert region.
Please see our schedule of upcoming talks for Fall 2013.
Now adding speakers for Spring 2014!
Please consider donating to the UA Herbarium. Any amount helps!
