Saussurea erecta, described from a single specimen, differs from S. kingii only by its more erect habit and glabrous achenes. Saussurea kingii is variable in growth habit, and glabrous achenes have been observed in some specimens of S. kingii as well. As long as these characters are not found to be stable in a larger population, we regard S. erecta as synonymous with S. kingii.
