Abstract

Ceanothus decornutus V. T. Parker is a newly described species found on serpentine outcrops in western Marin County. This taxon has been considered as part of C. jepsonii Greene in recent treatments. Ceanothus decornutus differs in a number of ways from C. jepsonii and suggests relationships to other northern San Francisco Bay species. Beyond the species description and a key to similar taxa north of San Francisco Bay, an analysis of leaf characters is used to indicate possible relationships.
