Discussion | A. Cronquist (1980) listed Solidago drummondii as reputedly in Louisiana; K. N. Gandhi and R. D. Thomas (1989) did not see any specimen from that state. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Subspecies 2 (2 in the flora). The arrays can be elongate with ends bent nearly 90–180°. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
