Discussion

Putative hybrids between var. velutinus and Ceanothus cordulatus, reported from the Klamath Mountains, the southern Cascade Range, and the Sierra Nevada, have been called C. ×lorenzenii (Jepson) McMinn. Putative hybrids between C. velutinus var. velutinus and C. prostratus (subg. Cerastes) and named C. ×rugosus Greene have been reported from northeastern California (H. McMinn 1944). Ceanothus ×rugosus, with spreading stems, opposite leaves, and wartlike, semipersistent stipules, is notable in being one of few intersubgeneric hybrids in Ceanothus.
