Saussurea amara var. glomerata
Saussurea amara var. glomerata was reported (as S. glomerata) from the vicinity of Debolt, Alberta (H. Groh 1943) and was included in The Thistles of Canada (R. J. Moore and C. Frankton 1974). I am not aware of any additional stations, and the persistence of these plants in the Debolt area is unknown.
