The University and Jepson Herbaria are two herbaria that share a joint facility at the University of California, Berkeley holding over 2,200,000 botanical specimens, the largest such collection on the US West Coast.^[1] These botanical natural history museums are on the ground floor of the Valley Life Sciences Building on the main campus of the university in Berkeley, California. There are ancillary collections such as the Marine Algal Collection, Fruit & Cone Collection, Horticultural Herbarium and Spirit Collection.^[2] The herbaria hold many type specimens, especially of Western North American and Pacific Rim plants. Holotypes are maintained separately for both herbaria. The Charterhouse School Herbarium is housed separately within the University Herbarium. The Herbaria have an open house every year on Cal Day with a range of activities for children and adults, and the Jepson Herbarium runs a series of workshops and public programs focusing on botanical education and the flora of California throughout the year.^[3]
