Checklist of the Vascular Plants of San Diego County
4th Edition

Format and Symbols

Checklist Format:
1) Major vascular plant groups are noted in BOLD CAPITALS.
2) Families are noted in BOLD SMALL CAPS.
3) Species and infraspecies are noted in Bold italics (ssp.=subspecies, var.=variety); full authorships for these taxa are listed generally from The Jepson Manual or Hortus Third (Bailey and Bailey 1976).
4) A representative herbarium voucher is shown in curly brackets "{ }", listing the herbarium acronym – from CAS-DS, CHSC, JEPS, POM, RSA, SD, SDSU, UC, IRVC, or UCR – and associated accession number.
5) Common names are noted in SMALL CAPITALS, and are derived from A Flora of San Diego County (Beauchamp 1986), The Jepson Manual, Hortus Third (Bailey and Bailey,1976), or from internet resources, especially CalFlora.
6) Environmental listing, where applicable, is noted in bold.
7) Synonyms (rejected names) and relevant information are listed within square brackets "[ ]". We list only those synonyms that are the accepted names in A Flora of San Diego County, The Jepson Manual, or other recent publications or citations. (See The Jepson Manual or the Jepson Online Interchange for a more complete list of synonomy.)
8) Pertinent notes regarding literature cited, taxonomy, distribution, rarity, or ongoing studies are indicated for selected taxa.

Checklist Symbols may precede taxa names to indicate:
* a taxon that is not native to the County, but has become naturalized, meaning that the taxon is persisting or spreading in natural, non-cultivated areas.
! a taxon that is an addition to the County not listed in A Flora of San Diego County (Beauchamp 1986).
a taxon that is not listed in The Jepson Manual. Note that some of these may be cited anecdotally in The Jepson Manual, but are not officially recognized there.
§ a taxon that is considered to be endemic to San Diego County. Note that some of these taxa are near endemic, having a single known population occurring just outside of the County’s border (e.g., the south side of Otay Mountain).
? a taxon (cited only in Appendix 1) that is doubtfully found in the County and has certainly or probably been misidentified in the past.
