Eupatorium leucolepis, commonly called justiceweed or white-bracted thoroughwort, is a herbaceous perennial plant in Asteraceae native from the eastern coastal United States, from New York to eastern Texas, with scattered populations inland as far as Kentucky and West Virginia.[3]
Eupatorium paludicola and Eupatorium novae-angliae
Eupatorium paludicola consists of diploids from clay soils of North Carolina and South Carolina. Until the early 21st century, they were classified in E. leucolepis. Eupatorium novae-angliae, known from a dozen or so sites in Massachusetts and Rhode Island, is a hybrid-derived allopolyploid of Eupatorium paludicola and Eupatorium perfoliatum. In the past it was known as E. leucolepis var. novae-angliae but, like E. paludicola, it does not appear to be closely related to E. leucolepis.[4][3][5]
It is self-sustaining, rather than being found only where both parents are present, so various authors since 1992 have proposed treating it as a distinct species.[6]
