Antennaria suffrutescens
Antennaria monocephala
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).

Subspecies 2 (2 in the flora).
It seems reasonable to follow in part E. Hultén’s (1968) broad concept of Antennaria monocephala (R. J. Bayer 1991). Hultén circumscribed it as containing three subspecies. The sexual phase of A. monocephala (i.e., subsp. monocephala and subsp. philonipha) is known from southern Alaska, south of the Brooks Range, and to Yukon Territory and adjacent areas of the Northwest Territories and across the Bering Strait on the Chukotka Peninsula. Within his concept of A. monocephala, Hultén also circumscribed the presumably autopolyploid apomictic form of the species as A. monocephala subsp. angustata, thereby extending the range of the species across the Canadian arctic into Greenland and down the western Cordillera into Montana and Wyoming.
Antennaria monocephala subsp. monocephala is an amphimictic progenitor of the A. alpina agamic complex, as well as the sexual progenitor of the apomicts of subsp. angustata.
