Discussion

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).

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.
