|discussion=<p><i>Ceanothus roderickii</i> is restricted to a few localities in the foothills of the Sierra <i>Nevada</i> (El Dorado County). A close relationship to <i>C. cuneatus </i>var.<i> cuneatus</i> is supported by molecular data (T. M. Hardig et al. 2000b). The ability to root at remote, distal nodes was shown to enhance density and recovery, long after episodic establishment from seeds following fires (R. S. Boyd 2007).</p><!--
