The combined Herbarium of Rancho Santa Ana Botanic Garden and Pomona College ("RSA") is about the tenth largest in the U.S. and the third largest in the western U.S., with current holdings totaling over 1,100,000 specimens. The Garden's herbarium is recognized for its strength in plants of California, which constitute nearly 50% of the total collection; holdings from southern California exceed 250,000. Active collecting over many decades means that the specimens are well distributed through time as well as in their geographic origin. The RSA-POM herbarium is an active member of the Consortium of California Herbaria .
