Discussion | 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).
