|discussion=<p>Variety nipomensis occurs primarily on Nipomo Mesa and the eastern San Luis Range of southern San Luis Obispo County. R. F. Hoover (1970) regarded it as derived from hybridization between <i></i>var.<i> impressus</i> and <i>Ceanothus oliganthus</i>. However, there is little evidence to indicate that populations of these two taxa overlap in geographic and ecological range. We treat <i></i>var.<i> nipomensis</i> as part of <i>C. impressus</i>, based on its furrowed veins and fruit morphology. Urbanization has reduced the number of known populations to a relatively few, scattered localities.</p><!--
--><p>Variety nipomensis is in the Center for Plant Conservation’s National Collection of Endangered Plants.</p>
