Discussion | 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.

Varieties 3 (3 in the flora). Ceanothus gloriosus is composed of three varieties occurring along the northern California coast from Humboldt County to Marin County. Variety gloriosus and var. porrectus generally differ primarily by leaf shape, length and width, and the number of marginal teeth. Variety exaltatus differs from the other two varieties primarily in stature. Complex hybrids with C. cuneatus var. ramulosus, C. divergens, and C. sonomensis were studied by J. T. Howell (1940).
