Discussion

Subspecies manzanita is widely distributed from the Diablo Range in the interior central coast northward around the southern Cascades and southward along the western slope of the Sierra Nevada. It occurs in open stands or as solitary, arborescent individuals. In the North Coast Ranges, apparent hybrids with Arctostaphylos stanfordiana are commonly encountered; they are shiny-green-leaved plants bearing immature inflorescences with very slender, many-branched panicles.
