Other Notes:

This subspecies and var. viridis from the vicinity have an appearance in common, both being heathlike, or their closely packed rigid leaves give the branches an aspect like spruce or fir twigs. Subsp. compactifolius marks the northernmost outpost in central Arizona for the occurrence of the closely appressed puberulence on the leaves that marks the material to the south and east. In the Flagstaff region intergrades occur between this and subsp. Sileri and the var. viridis.
