Of conservation concern. Arctostaphylos montereyensis is known from sandy soils, ranging from dunes to sandstone outcrops, in the southern Monterey Bay area, Monterey County. Plants found on Fort Ord with auriculate leaf bases and blue-green leaves may represent hybrids with A. pajaroensis. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
