Solidago ericamerioides Nesom is a very rare species known from one location in Nuevo Leon, Mexico.  Semple and Beck (2021) placed it in its own section (S. sect. Suffrutescentes Semple & J.B. Beck) in S.Ìý²õ³Ü²ú²µ.ÌýTriactis Raf based on its position in the polygenomic phylogeny of Solidago (Semple et al. 2023), thus it is the most basal member of the basal subgenus in Solidago. The type specimen is a small suffrutescent perennial with rounded flat-topped inflorescences.  The lower portions of the stems are woody and can have persistent leaf bases like Chrysoma pauciflosculosa, the sister taxon to Solidago.  The chromosome number is unknown.
