The broadest-leaved forms of the species occur in var. flaccidifolia. They can be confused with Solidago flexicaulis but lack the flexuous distal stem of the latter. A collection seen from north-central Mississippi is significantly disjunct from the nearest populations in extreme northeastern Alabama.
