Flora of Bolsa Chica Marsh

Bob Muns, 1983, 1999

Latin names in parentheses are probable, but not certain, identifications.

An enhanced version of this page has been created by Mark Bixby. It contains the following additions:

  1. Each Latin name has been hyperlinked into the http://plants.usda.gov/ database.

  2. A column has been added which shows the wetland indicator status (if any) for each species.

  3. A column has been added with links to photographs of each species, usually from CalPhotos.

  4. Some of the Latin names have been updated. Those names have been highlighted in yellow but with the original names retained here.

  5. Red highlighting has been added for wetland status indicators with conflicting information in the USDA PLANTS database; i.e. different varieties of a species are listed with different indicator values, etc.

Due primarily to the links, this enhanced version of the page is significantly larger, 164 kB compared to the 30 kB of this page.
