The Herbarium at California Botanic Garden, the third largest in California, comprises over 1,250,000 specimens of vascular plants and a growing collection of bryophytes. The collection represents the combined holdings of the Botanic Garden’s collection [RSA] and the Pomona College Herbarium [POM]. The Herbarium’s holdings include nearly 7,000 type specimens (holotypes, isotypes, lectotypes, isolectotypes, neotypes, and isoneotypes) housed separately from the main collection. In addition to traditional herbarium sheets, the Herbarium also houses an ancillary collection of wood specimens, fluid preserved specimens, a cone and fruit collection, and nearly 100,000 anatomical and palynological microscope slides.
The Herbarium is worldwide in geographic scope, with significant holdings from the southwest U.S., Mexico, Australia, Russia, and other regions of arid, semi-arid, and Mediterranean climates. The Herbarium is one of the world’s largest repositories for specimens of vascular plants collected in California, notably southern California. Taxonomic strengths of the collection include Boraginaceae, Cactaceae, Ericaceae (Arctostaphylos), Fabaceae (Astragalus), Goodeniaceae, Lamiaceae, Phrymaceae, Poaceae, Polemoniaceae, The Herbarium is unique in that its holdings have grown substantially in a relatively short amount of time, in large part due to a number of resident botanists who made significant contributions to the Herbarium over the years. Especially noteworthy of CalBG’s botanists include Charles F. Baker, R. C. Barneby, Duncan Bell, Lyman D. Benson, Steve Boyd, Sherwin Carlquist, Ansthruther Davidson, C. Davidson, P. H. Davis, Mary DeDecker, Sarah J. De Groot, M. B. Dunkle, F. R. Fosberg, Naomi Fraga, H. S. Gentry, Verne Grant, R. Gustafson, G. B. Hinton, E. C. Jaeger, Marcus E. Jones, C. L. Lundell, Y. E. J. Mexia, Philip A. Munz, Edward Palmer, F. W. Peirson, C. G. Pringle, Peter H. Raven, J. C. Roos, Andy C. Sanders, Robert F. Thorne, Louis C. Wheeler, and Carl B. Wolf.
More than 560,000 (45%) of the >1.25 million herbarium specimens held by RSA-POM have been databased, and includes all of our California holdings as well as many specimen records in North America and worldwide. Approximately 10% of our specimens have been imaged. Records and images are available through the Consortium of California Herbaria Portal (http://cch2.org/portal/).
