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

17 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. ITIS now lists T. atropurpurea as a synonym for
Berylsimpsonia vanillosma which at least adds some humor to the situation.

ITIS Taxonomic Serial No. 780532
