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.
Section 6 Program: 2014 awards will be announced soon.
Schedule of talks for Fall 2014 is under development; please contact us if you'd like to hear announcements or give a presentation.
Please consider donating to the UA Herbarium. Any amount helps!
