Discussion

Ceanothus parryi occurs in the outer coast ranges of Oregon (Benton and Lane counties) and from Humboldt County south to Napa County in California; it is reported to hybridize with C. foliosus, C. incanus, and C. thyrsiflorus (H. McMinn 1944). The deep blue sepals and petals, cobwebby indumentum on young leaves, and narrowly revolute leaf margins are diagnostic.

Ceanothus verrucosus occurs from San Diego County to the foothills of the Sierra San Pedro Mártir and Cedros Island in northern Baja California, Mexico; its habitat is threatened by development and urbanization throughout its range.
