RSA Herbarium specimen

 RSA-POM Herbarium

The combined Herbarium of Rancho Santa Ana Botanic Garden and Pomona College ("RSA-POM") is about the tenth largest in the U.S. and the third largest in the western U.S., with current holdings totaling over 1,000,000 specimens. Approximately 95% of the collection is composed of mounted sheets which are housed in four rooms (wings) within the Plant Science Center Building. The Garden's herbarium is recognized throughout the world for its strength in plants of California, which constitute nearly 40% of the total collection. The holdings from southern California are unsurpassed by any other herbarium. In recognition of its overall strength, RSA-POM has been designated a national Research Resource Collection.
