Eupatorium leucolepis, commonly called Justiceweed or white-bracted thoroughwort, is a herbaceous perennial plant in Asteraceae native from the eastern coastal states of the USA, from New York to Texas.[2]
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 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.[3][2][4] 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.[5]
