Notes: Subspecies pulvinata is for us the most problematic of the subspecies of Antennaria rosea as Bayer (2006) included in it one of the three species described as agamospermous Greenland species of sect. Dioicae (A. affinis) and also some northeastern North American species (e.g., A. gaspensis), whereas a second Greenland species previously assigned to sect. Dioicae (A. hansii) is absent from his treatment and synonymy, and a third (A. intermedia) is assigned to a different group. Antennaria hansii and A. intermedia are entered provisionally below until their relationships are clarified. It is, however, probable that these Greenland plants - both that included by Bayer and those not - have their relationships to North American groups and not to the sexual Eurasian A. dioica as previously assumed. Antennaria affinis is reported with an interrupted range in western Greenland.
Another point is the possible relationship to A. media. Chmielewski (1997) accepted A. media with three subspecies: subsp. compacta, subsp. fusca, and the non-arctic subsp. media. Bayer (2006) considered A. media subsp. fusca a synonym of A. rosea subsp. pulvinata and included subsp. compacta in his collective A. alpina, see below. Bayer did not refer to Chmielewski's treatment and did not argue for his solution. We follow Chmielewski until arguments are available and can be evaluated.
