Discussion
Rhamnus pilosa is known only from San Diego County and extreme southwestern Riverside County. The species has been reported from Arizona and Mexico (Baja California) (USDA Plants Database, based on L. Abrams and R. S. Ferris 1923–1960, vol. 2), but no specimens have been found to support this claim.
Selected References
None.
