Antennaria neglecta
Antennaria alpina
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 alpina is one of the more morphologically variable agamic complexes in the genus. Some taxonomists have argued that true Antennaria alpina does not occur in North America, because none of the North American material exactly matches the type of A. alpina, which is from Lapland (M. O. Malte 1934; A. E. Porsild 1965). If one uses a strict typological species concept, then this is true; I recognize that this species complex is composed of innumerable apomictic clones and am circumscribing a broad species concept for A. alpina. The potential morphologic overlap between the A. media and A. alpina complexes is a major taxonomic problem. The chief difference between members of the two complexes is the presence of prominent flags on cauline leaves in A. alpina and their absence in A. media. Antennaria alpina of North America is gynoecious and characterized by its dark green to black phyllaries and conspicuous flags on the distal cauline leaves. The basal leaves vary from glabrous, as in the type material, to pubescent. The primary progenitors of the A. alpina complex include A. aromatica, A. densifolia, A. friesiana subsp. alaskana, A. friesiana subsp. neoalaskana, A. monocephala subsp. monocephala, and A. pulchella.

Some Antennaria names are based on early-generation interspecific hybrids, including:
Antennaria ×erigeroides Greene = A. corymbosa × A. racemosa
A. ×foliacea Greene = A. microphylla × A. racemosa
A. ×macounii Greene = A. media × A. umbrinella
A. ×oblancifolia E. E. Nelson = A. racemosa × A. umbrinella
A. ×rousseaui A. E. Porsild = ? A. alpina × A. rosea
