Overview
Distribution
Dudleya cymosa is endemic to California. The California distribution includes the North Coast Ranges, Cascade Range, Sierra Nevada, Central Western California (except the Central Coast), and the Transverse Ranges. Each of the eight subspecies has a rather well defined geographic distribution, usually associated with specific canyons within one or more mountain ranges. Some of these subspecies distributions are highly restricted, leading to conservation designations of "rare" or "limited distribution" by the California Native Plant Society.
