Discussion | Arctostaphylos hispidula is known from Josephine County, Oregon, and adjacent California in Del Norte and Humboldt counties; there is an isolated population in northern Sonoma County, California. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Arctostaphylos glauca is widespread, occurring from Mount Diablo in central California through the southern Coast Ranges, east through the Transverse Ranges into the desert, and south in the Peninsular Ranges into northern Baja California, usually in drier interior ranges. It is distinctive throughout its range; however, some populations have nonglandular twig puberulence and others are stipitate-glandular, often mixed in with individuals that are typically glabrous. Arctostaphylos glauca can be a component of chaparral and can also be found in woodlands and at the edges of grasslands.
