Compiled March 6, 2007 from
voucher data provided by the participants of the
Consortium of California Herbaria,
CalFlora species data, and
Tom Chester's database of Southern California plants. The scientific name of all plants are current names as defined by the Jepson Flora
Project. The "R" column indicates plants
which appear in one of the
CNPS (California Native Plant Society) lists (1B, 2, 3, or 4) of rare and/or endangered plants. The "N" column identifies plants that are non-native with an "I" (introduced).
