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). The species includes polyploid series of 2x, 4x, and 6x plants (2n=18, 36, 54; Cook & Semple 2008).
Two varieties were recognized in FNA:
