The UC Davis Center for Plant Diversity is a university museum housing over 300,000 well-identified and taxonomically-organized pressed plant specimens (herbarium specimens), a botanical identification room (with microscopes), and a botanical library. Herbarium specimens worldwide can be as old as 500 years old and are the basis for much of what is known about plant evolution and distribution. Our
museum is mainly used by those who wish to identify plants, but our specimens have also been used to track the introduction of new weeds or viruses, study the evolution of plant groups, or look at plant distributions; they can be used as a source of DNA. We are strongly committed to serving our community, including the students, faculty, and staff of UC Davis, county farm advisors, the general public, and botanists in California, across the US, and internationally.
