|discussion=<p><i>Ceanothus pumilus</i> is endemic to the Klamath Mountains, where it occurs strictly on serpentine soils; it sometimes has been confused with <i>C. arcuatus</i> and <i>C. prostratus</i>, from which it differs principally by its oblanceolate to oblong-lanceolate leaf blades with a truncate, 3-toothed apex.</p><!--
--><p>Hybrids between <i>Ceanothus pumilus</i> and <i>C. cuneatus</i> have been called C. ×humboldtensis Roof.</p>
