Herbarium Data Resources

The Herbaria maintain a number of specimen databases and other data resources that are publicly available from this website.

  • The UC/JEPS Specimen Portal, powered by CollectionSpace, is a gateway to all digitized records, including images where available, of plant specimens held at the Herbaria. Jepson (JEPS) specimens are limited to vascular plants collected in California, while University Herbarium (UC) specimens include all major plant groups from all over the world.

    Additional records of UC specimens for fungi, lichens, and macroalgae are currently available through the Symbiota collaborative digitization portals MycoPortal, CNALH, and Macroalgal Herbarium Portal.

  • The Consortium of California Herbaria (CCH) is a project which gathers records of California vascular plant specimens from many institutions, including UC and JEPS. The records can be searched on taxon name, collector, collection date, location information, source herbarium, and geographic coordinates. Point maps can be generated and lists and other data downloads available. Currently, the CCH hosts over 1.8 million herbarium specimen records from 30 participant institutions.

  • The UC Bryophyte Database presents data from nearly 70,000 of Dan Norris's 110,000 bryophyte specimens, and 25,000 of Jim Shevock's specimens (Shevock's first set is at CAS but most are duplicated at UC), as well as specimens databased by Paul Wilson at California State University at Northridge.

  • The University and Jepson Herbaria maintain lists of our type specimens. We have ongoing and past projects to digitize type specimens of algae, fungi and lichens, ferns and allies, and angiosperms at the Herbaria. Images are also available for Galapagos marine algae and many vascular plant types.

  • The Jepson Online Interchange provides the latest information on identification, taxonomy, distribution, ecology, relationships, and diversity of California vascular plants. The professional resources of the Jepson Herbarium assure high quality, with editorial review of all scientific content. Read more...

  • The Index to California Plant Names (ICPN) is intended to account for names people are likely to encounter, from whatever source, and to summarize the status of such names with respect to the flora of California as it is understood presently by authors contributing to the Jepson eFlora.

  • The Index Nominum Algarum (INA) is a card file maintained at the Silva Center for Phycological Documentation at the Herbaria. It contains nearly 200,000 names of algae (in the broad sense).
