Antennaria neglecta
Antennaria friesiana
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 3 (3 in the flora).
The Antennaria friesiana complex consists of subsp. alaskana, subsp. neoalaskana, and subsp. friesiana, the former two are dioecious (sexual) phases of the latter gynoecious (asexual) form. The sexual populations are known from Alaska and cordilleran areas of northern Yukon and adjacent Northwest Territories (R. J. Bayer 1991). The apomictic phase is almost circumpolar, occurring from the central and eastern Siberian plateau eastward across the North American arctic to Greenland (Bayer). E. Hultén (1968) circumscribed a fourth subspecies, A. friesiana subsp. compacta. After studying its morphology, in the field and herbarium, it is apparent that Hultén’s taxon contains at least three incongruous entities that are probably not at all related to the other two subspecies of A. friesiana. Hultén’s subsp. compacta included A. densifolia, which is recognized as a distinct species, and A. crymophila and A. neoalaskana as taxonomic synonyms. Antennaria compacta in the strict sense and A. crymophila are perhaps hybrid apomicts and are treated here in A. alpina (see Bayer for details). Antennaria neoalaskana is treated here as a subspecies of A. friesiana.

1. Stolons 1–4 cm (usually prostrate, sometimes ascending, usually rooting at tips, plants forming mats); involucres: pistillate 7–8 mm | subsp. neoalaskana |
1. Stolons 0.5–1 cm (erect, usually not rooting at tips, plants not forming mats); involucres: pistillate 5.5–7 mm | → 2 |
2. Plants gynoecious (staminates unknown) | subsp. friesiana |
2. Plants dioecious (staminates and pistillates in equal frequencies in populations) | subsp. alaskana |
