Discussion | 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.
