The Jepson eFlora contains taxonomic treatments and identification keys for native and naturalized plants occurring in wildlands or otherwise outside of cultivation in California. Documented waifs and some agricultural weeds are also included.

Dec. 19, 2014: Revision 2 is posted online. Summary of Revision 2, including link to a supplement for TJM2.

About the Jepson eFlora

Treatments and keys in the Jepson eFlora were initially derived from The Jepson Manual: Vascular Plants of California, Second Edition (TJM2), available from University of California Press.

The eFlora expands on the content of TJM2, including descriptions of taxa not included in the print book (e.g. waifs, agricultural weeds), substantive revisions of scientific content for some taxa, and many errata and other small changes made relative to the print book.

The eFlora also contains maps based on specimens from the Consortium of California Herbaria, plant photographs from CalPhotos, and links to the Jepson Online Interchange, which includes more complete synonymy information from the Index of California Plant Names (ICPN).

The Jepson eFlora is a product of the Jepson Flora Project.
