Discussion

Subspecies pillsburiensis is known from a single population near Lake Pillsbury, North Coast Ranges, Lake County. It appears to be a dwarf most closely related to subsp. viridis and differing in its lower stature, undivided (non-two-fid) bracts, fewer flowers, and less conspicuous, appressed indument.
