PLANTS OF THE EASTERN SAN GABRIEL MOUNTAINS
 My appreciation to Tom Chester who posted the first list of plants from my collection on his web page. He obtained this list from accessing the UCR Herbarium digital data base. Tom converted the plants on that initial list to currently used taxa if necessary, and included common names for each as well. The location map was made by Tom as well. All names used in this publication, unless otherwise stated, conform to The Jepson Manual Higher Plants of California, James C. Hickman, Editor, 1993. Exceptions: New changes in species names since The Jepson Manual, 1993 are being used here as they become known. These species will be indicated by the symbol + These names have been taken from the USDA Plant Database unless otherwise indicated. The + may only indicate that the former subtaxa have been dropped. * = California is the only state in the United States and Canada that this plant occurs. Common Names: When more than one name is given, the last name has been taken from the USDA Plant Databae Last Update: 5/27/08 Ferns & Fern Allies Azollaceae Mosquito Fern Family Azolla filiculoides Lam.
