"Habitat in America septentrionali." RCN: 6065. Lectotype (Wiegand in Rhodora 22: 59. 1920): Kalm , Herb. Linn. No. 978.15 ( LINN ) . Current name: Eupatorium maculatum L. ( Asteraceae ). Note: Although Mackenzie (in Rhodora 29: 8. 1927) maintained that this Kalm material could not have been the basis for the name, this seems incorrect and Wiegand's type choice is accepted here. Lamont (in Mem. New York Bot. Gard. 72: 36. 1995) recognised E. maculatum L. as a species distinct from E. purpureum L. He also illustrated the type (as f. 25).
