The University of Arizona Herbarium is home to more than 400,000 research plant specimens, including algae, mosses, conifers, and all manner of flowering plants. We specialize in plants of the Sonoran Desert region, including the associated mountain ranges and the particularly diverse northern Sierra Madre Occidental of México. Tours, consultation, and plant identification services are available, as are countless opportunites to volunteer.
