The Jepson Flora Project (Jepson Herbarium, University of California at Berkeley) maintains an updated checklist and distribution maps of plant taxa in California. This information was first published as The Jepson Manual (named after the original author) and is now an extensively illustrated guide to California's plants, refined and updated by over 200 authors. The Manual includes detailed descriptions of plant characteristics, current distributions, and horticultural potential. To search the checklist to examine distribution maps, users may enter scientific name or browse the Family Indices (Ferns and fern allies, Conifers and gnetophytes, Dicots, or Monocots). Typical returns include scientific and common name, status (native or non-native), elevational range, chromosomal number, and California Bioregional Distribution. An additional link points users to other taxa with the same California distribution.
