Ceanothus lemmonii occurs in the inner North Coast Ranges, Klamath Mountains, and the western slope of the Cascade Range and northern Sierra Nevada. H. McMinn (1944) reported putative hybrids with C. foliosus, C. integerrimus, and C. oliganthus var. sorediatus. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Ceanothus ferrisiae, federally listed as endangered, occurs at a few localities in the foothills of the Mount Hamilton Range northeast of Morgan Hill, Santa Clara County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
