Tephroseris atropurpurea (Ledeb.) Holub
(Tephroseris frigida (Richardson) Holub

11 photos.
This is the "Purple Haired Groundsel (GBIF)" and is similar to Tephroseris kjellmanii, Kjellman's groundsel, differing
in having an involucrum which is merely tomentose rather than floccose-tomentose. In other words,"the
bracts (phyllaries) surrounding the flower aren't as hairy".  Frigida, like Kjellmanii, will sometimes
have very short ligules.  All photos taken on June 12, 2009.  T. atropurpurea is now listed as a synonym
for T. frigida.
