Solidago retrorsa was published by André Michaux in 1803 and placed in synonymy under S. odora by Asa Gray (undated annotation). The Michaux herbarium includes five sheets that are likely original material on which typification of the name can be based. One of these collections is selected as the lectotype and two other collections are considered to be possible isolectotypes or syntypes; all are identified as S. odora. The fourth and fifth collections treated as S. odora are identified as S. tortifolia, an unrelated species.
