The combined Herbarium of California Botanic Garden (RSA) and Pomona College (POM) is a museum-quality collection of vascular plant and bryophyte specimens. With current holdings totaling over 1,250,000 specimens, the Herbarium is the third largest in California. The Herbarium is recognized throughout the world for its strength in documenting the diversity, distribution, variation, and ecology of more than 6,500 species of flowering plants, conifers, and ferns in California, which constitutes nearly 50% of the total collection. The holdings from Southern California exceed 250,000 and are unsurpassed by any other herbarium. Approximately 95% of the collection is composed of mounted sheets and filed according to a standardized system of classification. Ancillary collections that augment the collection include a cone & fruit collection, wood collection, fluid preserved collection, and pollen and anatomy slide collection.
