Welcome to the new website of ARIZ, the Vascular Plant Herbarium at the University of Arizona in Tucson.
With over 400,000 specimens, ARIZ is the largest collection in the world 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 major provider of information on the plants of Arizona and the Sonoran Desert region.
We invite you to explore the many resources at ARIZ by following the links at left.
