| Notes | Male plants are unknown in subsp. angustata; agamospermous. This is the agamospermous parallel to subsp. monocephala (Bayer 2006) and with a much wider range than the sexual race. It reaches from West Chukotka across Alaska and Canada to western Greenland. Bayer (1993, 1996, 2006) assigned a series of eastern Canadian species names in the synonymy of this subspecies, e.g., Antennaria burwellensis, A. congesta, A. fernaldiana, A. hudsonica, A. pygmaea, A. tansleyi, and A. tweedsmuirii. |
