The UC Davis Center for Plant Diversity Herbarium focuses on undergraduate and graduate student training as well as outreach and service. The herbarium is made up of several University of California herbaria that once were housed separately. The majority of our specimens belong to either the J. M. Tucker Herbarium (DAV), which was originally the Botany Department Herbarium, or the Beecher Crampton Herbarium Collection (AHUC), which was the Agronomy Department Herbarium. In recent years, we have also incorporated the UC Viticulture Herbarium and the Environmental Horticulture Herbarium into the Tucker Herbarium. The J.M. Tucker Herbarium had a historical emphasis on weeds and weed identification.
The Crampton Herbarium had a historical emphasis on California range plants. The combined herbarium, which is worldwide in scope, houses approximately 300,000 specimens, including ca. 300 type specimens (holotypes or isotypes). Geographic strengths of the herbarium are California, Texas, the neotropics (especially Ecuador and Baja California), and the alpine flora of western North America. Taxonomic strengths are Euphorbiaceae, Poaceae, Quercus , Arctostaphylos , Navarretia , Trifolium , Capsicum , Lycianthes , and Lycopersicon .
