Curtis’ or Appalachian Goldenrod
Solidago curtisii Torr. & A. Gray is native to much of the Appalachian Mts in eastern North America. Stems are erect and straight, not bent as in S. flexicaulis (Semple & Cook 2006 FNA). Two varieties were recognized in FNA var. curtisii and var. flaccidifolia, which are now treated at the species level as Cronquist (1980) had done. The species includes a polyploid series of 2x, 4x, and 6x plants (2n=18, 2n=36, 2n=54; Cook & Semple 2008).
