Abstract

We describe Frangula purshiana (DC.) Cooper subsp. ultramafica J. O. Sawyer & S. W. Edwards, an endemic to the Sierra Nevada in Plumas National Forest, and compare it with other subspecies of F. purshiana. We discuss the use of the generic names Frangula and Rhamnus in the California flora. We also make a new combination Frangula purshiana (DC.) Cooper subsp. annonifolia (Greene) J. O. Sawyer & S. W. Edwards.
