Antennaria neglecta
Antennaria monocephala
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).

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.
