Antennaria suffrutescens
Antennaria dioica
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).

Antennaria dioica ranges from the British Isles to Japan and into the Aleutian Islands (R. J. Bayer 2000). It is characterized by glabrous adaxial leaf faces and distally pink or white phyllaries. The circumscription of A. dioica in North America has long been debated; A. marginata of southwestern states bears a remarkable similarity to A. dioica. DNA sequence data (Bayer et al. 1996) indicate that the two taxa are not sisters; they are only distantly related. They are allopatric. Antennaria dioica may be a sexual progenitor of the A. parvifolia complex.
