The lower leaves of this species resemble those of S. flexicaulis but the inflorescences of the two species are completely different. Might also be confused with S. patula which is a plant of wetlands and has rather strongly angled stems and leaves that are scabrous above. Occasional plants with rather narrow lower leaves might be confused with S. ulmifolia which has fewer than 8 disk flowers per head.
