Antennaria microphylla
Antennaria friesiana
Antennaria microphylla is a primary sexual progenitor of the A. rosea polyploid agamic complex (R. J. Bayer 1990b). A. Cronquist (1955) included A. rosea within his circumscription of A. microphylla. It is preferable to recognize sexual diploids as distinct from their morphologically discrete hybrid apomictic derivatives. Antennaria microphylla is always dioecious and has stems distally stipitate-glandular and white phyllaries; A. rosea is always gynoecious and has stems without glandular hairs and phyllaries only occasionally white.
Some authors (A. E. Porsild 1950; E. H. Moss 1959; Porsild and W. J. Cody 1980) have recognized A. nitida as distinct; comparisons of the nomenclatural types of the two show that they are conspecific. Antennaria microphylla has allelopathic properties (G. D. Manners and D. S. Galitz 1985).

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 |
