Antennaria suffrutescens
Antennaria densifolia
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 densifolia is found on limestone talus below treeline in the MacKenzie, Richardson, and Ogilvie mountains of the District of MacKenzie and Yukon Territory and in Granite County, Montana (R. J. Bayer 1989c). It differs from A. aromatica in being non-glandular and in other characters. Herbarium specimens (in DAO) from British Columbia that morphologically appear to be a strictly gynoecious form of A. densifolia may be apomicts related to A. alpina that are derived from A. densifolia, a sexual progenitor of the complex.
