Antennaria suffrutescens
Antennaria aromatica
Antennaria suffrutescens is characterized by suffrutescent growth form, relatively small, emarginate, adaxially glabrous, coriaceous leaves, and relatively large heads borne singly. It is known only from serpentine soils in open montane pine forests in Curry and Josephine counties, Oregon, and neighboring Del Norte and Humboldt counties, California (R. J. Bayer and G. L. Stebbins 1987). Antennaria suffrutescens may have contributed to the origin of some of the clones of the A. rosea complex (e.g., J. T. Howell 27718, NY).

Known only from the northern Rockies, Antennaria aromatica is characterized by glandulosity, cuneate leaves, and odor of citronella in crushed leaves of living material. It is most closely related to A. densifolia of the Northwest Territories and Yukon (R. J. Bayer 1989c). Some collections of pistillate plants from Colorado and other areas of the Rockies superficially resemble A. aromatica and undoubtedly have A. aromatica in their parentage. They are non-glandular and odorless and are closer to the type of A. pulvinata, which is included in the circumscription of A. rosea, as A. rosea subsp. pulvinata (Bayer). Antennaria aromatica is a sexual progenitor of the A. rosea and A. alpina polyploid complexes.
