About the Consortium
The Consortium of California Herbaria was developed to serve as a gateway to information from California vascular plant specimens that are housed in herbaria throughout the state.
The database now (May 2008) includes information from about 959,000 specimens, all searchable through a single interface.
Originally developed in 2003 around botanical collections from University of California herbaria, the consortium continues to grow as more collections are added.
Currently, collections from seventeen institutions are accessible through this interface.
The participating institutions cooperate under the guidelines of a Memorandum of Understanding.
Participation as a data provider to the Consortium database is open to California herbaria that meet these Minimum Requirements for data inclusion.
The data included in this database are a snapshot of the California vascular plant collections at partner institutions.
More recent data may be available through the individual herbaria.
Some participating herbaria have collections of fungi, lichens, and bryophytes; those specimens are not included here. The holdings of the participant herbaria for each county of California have been summarized by a set of bar graphs.
Please send any feedback regarding the specimen data directly to the curator of each participating herbarium .
The Consortium is in the process of completing an Index to California Herbaria that will survey all herbarium collections in the state. The original information comes from the List of California Herbaria and Working Collections by G. Douglas Barbe and Thomas G. Fuller published in 1987 by the State of California Department of Food and Agriculture. We will be updating information for each collection and adding new collections to the list.

Geographic Data
Another goal of the consortium is to provide coordinate data (latitude/longitude) for as many California specimens as possible. Currently, specimens from all twelve participating institutions are being georeferenced on a county-by-county basis. Nearly 400,000 specimens have been georeferenced as of January 2008. Using BerkeleyMapper, the georeferenced specimens returned from any Consortium search can be mapped directly from the Consortium accession results page. Additional search options may be available from the BerkeleyMapper home page.
