Southern California Wildflowers
Common names C-D


Brackets [ ] indicate taxa not necessarily recognized by the Jepson Manual but which I think are deserving of separate listings because they are so very different. Names preceded by the word 'Common' in brackets such as [Common] Hawkweed are not necessarily the most common species of the genus, but simply do not have any other descriptive name. The use of the name [Common] in this context is solely for indexing purposes.
