Name Changes

          Any one with more than a passing knowledge of botany knows that there have been and will continue to be changes in the accepted names of plants. Unlike the case with birds, there is no national organization to set either scientific or common names of plants in the various regions of the United States. The International Code of Botanical Nomenclature establishes a uniform set of rules to be used in applying names to plants, and is revised by the International Botanical Congresses which are held every six years. The 1st Botanical Congress was held in Paris in 1900, and procedures have been standardized globally during congresses since then. The edition of the code that is currently in effect was adopted by the 19th International Botanical Congress held at Shenzhen, China, in 2017. The next IBC was scheduled for Madrid in 2023 but has been postponed to 2024 due to the Covid-19 pandemic. Names that are changed must be be in accord with this set of rules. In California, the most current names are those that have been published in the most recent edition of the Jepson Manual and those that have been changed since its publication and maintained on the Jepson Online Interchange website.

This list is presented in two sections, former names to current names, and current names to former names. The purpose of including this information is to make it possible for myself or other people to look up the name of a taxon in my site that may have changed from the one they or I are familiar with, or to see what the former name of a plant was, so it is by no means a complete list of California nomenclatural changes but rather includes those taxa in my site. In the creation of this list I have relied heavily upon the work done by Tom Chester that is included in his webpage Plants of Southern California: Latin Name Changes. His list is far more extensive and more inclusive than mine. The Jepson Manual also has an appendix on name changes.
