Solidago erecta Banks ex Pursh occurs in the Appalachian Mts. and Piedmont and adjacent areas from southeastern Massachusetts west to southern Indiana and south Georgia and northern Mississippi (). It has been included in S. speciosa in the broad sense, but is more similar in many traits to S. bicolor,ÌýS. hispida,ÌýS. roanensis, and S. sciaphila. Stems are glabrous from the base to near or into the inflorescence. Fruits are usually glabrous. The species is known only at the diploid level 2n=18.
Semple et al. (2017a) included S. erecta in a multivariate study of theS. speciosa complex. Semple et al. (2017b) included ³§.Ìý±ð°ù±ð³¦³Ù²¹Ìýin a multivariate study of the S. bicolor complex along with S. hispida,ÌýS. porteri,ÌýS. roanensis, and S. sciaphila. In both studies,ÌýS. ±ð°ù±ð³¦³Ù²¹Ìýwas found to be distinct from the other taxa included. In the polygenomic phylogeny of diploid taxa in Solidago, S. erecta came up in a clade with S. speciosa (Semple et al. 2023).
