Common Name

Partial names are allowed (e.g., Parish). This search uses only the common names included in The Jepson Manual, Second Edition
These searches will retrieve entries in the Index to California Plant Names, which include hyperlinks to the Jepson eFlora, 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, source herbarium, and geographic coordinates. Point maps can be generated and lists and other data downloaded.

The Jepson eFlora contains taxonomic treatments for native and naturalized plants occurring in wildlands or otherwise outside of cultivation in California. Documented waifs and some agricultural weeds are also included. Treatments were initially derived from The Jepson Manual: Vascular Plants of California, Second Edition, available from University of California Press.
