Arctostaphylos malloryi
Arctostaphylos tomentosa
Of conservation concern.
Arctostaphylos malloryi occurs in disjunct populations on volcanic soils in Colusa, Shasta, and Sonoma counties in the North Coast Ranges. It possibly originated as a hybrid between A. canescens and A. viscida, and merits further study.
