These word meanings and name derivations of California plants have been taken from a variety of sources which are listed on a separate page. I am not an expert in Latin or Greek, and I make no firm guarantees as to the accuracy or legitimacy of these definitions. Further, I take no original credit for the work represented here, and claim merely to have compiled information from published and online sources and presented it in one location.  Many, indeed most, of the definitions and derivations that are presented here are drawn from David Gledhill's The Names of Plants, William Stearn's Dictionary of Plant Names for Gardeners, and Edmund Jaeger's A Source-book of Biological Names and Terms. When none of these produce a satisfactory entry, I have turned to the internet to such sites as the Biological Heritage Library and Flora of North America. Species publication information mostly comes from the International Plant Name Index (IPNI), World Flora Online (WFO) and the Tropicos website of the Missouri Botanical Garden. In addition to those many other sources I have relied on, I wish to acknowledge the work of Dr. Umberto Quattrocchi of Sicily, whose massive World Dictionary of Plant Names, published in 4 volumes, includes some 22,500 genera and well over 200,000 species. I particularly want to thank David Hollombe of the Santa Monica chapter California Native Plant Society for his tremendous research and fine scholarship, and for his numerous invaluable and unfailingly generous biographical contributions and corrections. Without his knowledge and help, this would be a far poorer effort. I also express appreciation to Orange County botanist Bob Allen for his help and friendship, and to Tom Chester, Jane Strong and Bob Muns, in whose company I have spent many enjoyable outings, and for whose friendship I am deeply grateful. I especially want to acknowledge the Herbarium and Education staffs at Rancho Santa Ana Botanic Garden who, although not directly involved in the creation of this work, have nevertheless helped me greatly in the identification of plant specimens, introduced me to numerous interesting and productive localities, and contributed greatly to the furtherance of my botanical knowledge and to my enjoyment of native plants. I have been extremely fortunate to have been able to benefit from the knowledge and experience of many professional botanists who have led or participated in field trips I've taken and shared their expertise such as Bruce Baldwin, Jim Andre, Tasha La Doux, Jon Rebman, Scott McMillan, Steve Junak, Dana York, Naomi Fraga, Fred Roberts, Steve Schoenig, Steve Matson, Tim Krantz, Jim Morefield, Jeff Greenhouse, John Game, Bob Allen, Neal Kramer, and others, and I thank them. For help with botanical terminology and etymology, particularly with Latin words, I express my appreciation to Mike Simpson and E. Nicholas Genovese at SDSU. I would be remiss in not also mentioning the wonderful online series of biographical essays entitled "Who's In A Name?" by Larry Blakely that are not only highly informative but equally fun to read. The Dave's Garden website with its Botanary section is also worthy of mention, as is the online Dictionary of Botanical Epithets and the Glossary of Roots of Botanical Names. There are other people who have occasionally written with suggestions and corrections, and I am always extremely appreciative for that.

A careful peruser of these pages may note different spellings for the same root word. This is unavoidable whenever a foreign language is translated into English.  In some instances different references give different derivations for the same name, reflecting perhaps a certain amount of guesswork.  It is not always easy or even possible to say where a name came from, what it means or what it refers to. Many of these names were assigned decades or in some cases centuries ago, and the namers have not always left records as to why particular names were selected. Sometimes the generic name alludes to a characteristic of a single species that may have been the first one of its genus to be identified but is not typical of all its related species, and therefore may seem oddly chosen.  Similarly, a specific name may reflect a characteristic that is not typical of all known subspecies or geographical variants.  In many cases, the reader will regretfully be left to guess for him or herself just how these meanings actually relate to the plant in question.  This list should therefore be considered mainly as an interesting source of information which may help to illustrate why some plants have the names they do, and may at least point people in the direction of learning more about the names of plants.

The reader should also be aware that a specific epithet for one genus might have a different derivation or meaning than the same epithet for another genus, just as the names baileyi or bakeri can refer to more than one individual. It is often difficult to discern exactly where these names came from, or what was in the mind of the author who published them. No doubt this may have resulted in mistakes in the derivations or meanings I have given for particular taxa. In many cases the author of the taxonomic name is no longer available to explain what he or she meant by the name or why it was chosen, and sometimes there was never any published explanation even while the author was alive. A source such as Stearn's Dictionary of Plant Names may give a derivation which applies to a taxon in Europe for example, but may not apply to our California taxon. There is no official compilation or other published work which may absolutely be relied upon, and I am only too aware that information given on the internet is not always accurate. For all these reasons the reader must be aware of the limitations of a site such as this, but I believe that I have made a good faith effort to present correct information, and am willing to change it if necessary.

In the names included here the stressed vowel is the one preceding the stress mark. It is not always easy to ascertain where such stress should be placed, especially in the case of epithets derived from personal names. Some may say IVES-ee-a, while others say I-vees-ee-a. In the case of epithets derived from people's names, I have tried to follow the principle of maintaining the stress of the original personal name, and have abandoned it only when it was awkward. Not everyone will agree with the choices I have made, but I have tried to follow the rules of pronunciation, despite occasional uncertainty on my part as to what is correct. A phonetic pronunciation guide for the names in my website is presented here, and an essay on principles of botanic name pronunction is given here. Where no credit is given for photos, they are in public domain mostly from Wikipedia.

Links at the bottom of the page will take you to sections on Southern California plant communities and the development of botanical nomenclature, as well as a 750-item glossary.  It will be updated periodically as new information becomes available to me.  Anyone wishing to see more of my photographs of Southern California flora in a larger format may look at my other websites, Southern California Wildflowers,  and Field Trips Photo Gallery.  I would greatly appreciate being contacted and corrected with any information contrary or supplemental to that herein noted, or any sources of information on plant names other than those listed on the sources page.  If requested, my consent will gladly be given for any non-commercial use of my photographs.

Please do not confuse this site with Calflora, the superb database of botanical information maintained by the Calflora Database in Albany, California.  My site is not affiliated with that organization, and anyone looking for that site is directed to go to:  http://www.calflora.org.
