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.
