Baccharis vanessae
''Baccharis vanessae'' is a rare California species of baccharis known by the common name Encinitas baccharis. It is native primarily to San Diego County, California, almost endemic to the county except for one population a few miles over the county line in Riverside County.〔(Calflora taxon report, University of California, ''Baccharis vanessae'' Beauch., Encinitas baccharis )〕 It is a member of the chaparral flora, especially among Torrey pines. It is a federally listed threatened species. Despite its name it is no longer present in Encinitas, but it is known from other parts of the county from the coastline to the mountains. There are perhaps 15 populations remaining, for a total of about 2000 individuals.〔(The Nature Conservancy )〕 Half the remaining occurrences are on land which may be cleared for development.〔
