The University of Arizona Herbarium (ARIZ) is a research collection of over 425,000 dried plant specimens, with emphasis on the plants of the Sonoran Desert region and adjacent areas of the southwestern United States and northwestern Mexico.
ARIZ is dedicated to identifying plants for members of the public, Arizona producers, Poison Control, anyone.
Legumes of Arizona
Legumes of Arizona: An Illustrated Flora and Reference will be a comprehensive account of the family Fabaceae in Arizona.
It is an ongoing effort to find funding to keep these projects alive, protect our specimens, and serve the public.
