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 at the University of California Press.

The eFlora has diverged from the print book in that it:

  1. includes descriptions not in the print book (e.g., waifs, agricultural weeds).
  2. includes errata and other small changes made relative to the print book, as individually listed and summarized here:
  3. includes direct links to the Consortium of California Herbaria.
  4. includes direct links to the Online Interchange for California Floristics, which includes the Index of California Plant Names (ICPN), wherein more complete synonymies than those in the print book are presented.
  5. includes substantive revisions of scientific content for some taxa, see Revision 1, and a link to a supplement for TJM2 (July 2013).
The Jepson eFlora is a product of the Jepson Flora Project.
