Antennaria neglecta
Antennaria aromatica
Antennaria neglecta is a sexual progenitor of both the A. howellii and A. parvifolia polyploid complexes and has one of the more widespread ranges among the amphimictic species in the genus in North America. Amphimicts generally have small ranges compared to those of the polyploid agamic complexes derived from them. Characteristic features of A. neglecta are its lashlike stolons that bear reduced leaves (except at the ends), flags on the distal cauline leaves, and basal leaves that are green-glabrescent with age (R. J. Bayer and G. L. Stebbins 1982).

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.
