Eupatorium leucolepis : ウィキペディア英語版 | Eupatorium leucolepis
''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 eastern Texas, with scattered populations inland as far as Kentucky and West Virginia.〔(【引用サイトリンク】 work = Flora of North America )〕 == ''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''.〔〔(【引用サイトリンク】 work = Integrated Taxonomic Information System )〕 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.
