Discussion | Plants of Ceanothus fendleri with glabrous leaves found throughout its range have been called var. viridis. The name C. fendleri var. venosus has been applied to plants with widely elliptic, villosulous leaf blades. Such plants are similar to C. buxifolius of northern Mexico (Chihuahua and Sonora), which has glabrous or sparsely puberulent leaf blades and ± persistent glands on denticulate leaf margins. Putative hybrids between C. fendleri and C. herbaceus in the eastern foothills of the Rocky Mountains were named C. ×subsericeus Rydberg.

Ceanothus parryi occurs in the outer coast ranges of Oregon (Benton and Lane counties) and from Humboldt County south to Napa County in California; it is reported to hybridize with C. foliosus, C. incanus, and C. thyrsiflorus (H. McMinn 1944). The deep blue sepals and petals, cobwebby indumentum on young leaves, and narrowly revolute leaf margins are diagnostic.
