Corollas: staminate 2.5–3 mm; pistillate 3–4.5 mm. Cypselae 1.2–1.8 mm; pappi: staminate 3–4 mm; pistillate 3.5–5 mm. 2n = 28, 56.


Phenology: Flowering summer.
Habitat: Arctic and alpine tundra, on or near dry rocky outcrops or sand ridges
Elevation: 500–1500 m

Discussion

Subspecies alaskana is dioecious (sexual) and known from Alaska and cordilleran areas of northern Yukon and adjacent Northwest Territories (R. J. Bayer 1991, 1993). It is a probable progenitor of the Antennaria alpina complex.
