About the Interchange
Search the Interchange using the Index to California Plant Names
Scientific Name

Partial names are allowed (e.g., Seq gig). You can retrieve all species in a genus by entering a genus name only. When entering infraspecific names, do not include the words "var.", "subsp.", or "f.".
Common Name

Partial names are allowed (e.g., Parish). This search uses only the common names included in The Jepson Manual (1993).
These searches will retrieve entries in the Index to California Plant Names, which include hyperlinks to accumulating treatments in the Jepson Manual II, the specimen databases, CalPhotos, and other sources of information about the California flora

Go to the Consortium of California Herbaria search page
The Consortium of California Herbaria consolidates specimen records from many California herbaria, including UC and JEPS. The records can be searched on taxon name, collector, collection date, location information and geographic coordinates. Point maps can be generated and lists and other data downloaded.
Dynamic concordance (Jepson Manual (1993) names to Jepson Manual II names)
Generate a list of taxa in UC and JEPS by county
(e.g., all species in Alameda Co. for which the Herbaria have specimens)
Generate a list of taxa by bioregion
(e.g., all species inferred from the Jepson Manual to be present in the White and Inyo mountains)
