Of conservation concern.
Variety stelligera is known from Coconino, Gila, and Yavapai counties in northern and central Arizona. The difference between vars. kaibabensis and stelligera rests on trichome density and the proportion of simple versus branched hairs on the leaves. These features are highly variable and we find no dependable characteristics separating populations on the North Rim of the Grand Canyon from those to the south.
