Antennaria media Greene[FNA19, HC2]
alpine pussytoes, Rocky Mountain pussytoes

Publication: Pittonia. 3: 286. 1898.

Origin: Native

selected vouchers: WTU

Notes: FNA19: "The main distinction between A. media and A. alpina is flags on distal cauline leaves present in A. alpina and mostly absent in A. media (Bayer 1990d). Phyllaries of the pistillate plants in A. alpina tend to be acute; they are blunter in A. media. At some point, it may be preferable to follow W. L. Jepson ([1923–1925]) and some later authors and treat A. media as a subspecies of A. alpina. Antennaria media appears to be an autopolyploid derivative of A. pulchella; genes from A. pulchella may have introgressed into the A. alpina and A. parvifolia complexes indirectly through A. media."
