Ageratina adenophora (Asteraceae) new species to the Italian alien flora and observations on its environmental threats
Keywords:
Ageratina Spach, Alien flora, Ecological impact, Eupatorieae Cass., ItalyAbstract
Ageratina adenophora is recorded for the first time in Italy (Campania region). Its naturalization status and ecology are discussed, also providing a morphological comparison with the related taxa (both occurring in Italy) A. ligustrina and Eupatorium cannabinum. Some remarks on potential threats for habitat and native flora are provided as well.
