Abstract:In this study we describe a new nothospecies, Cirsium ×sudae Michálková et Bureš, a homoploid hybrid between two rare Alpine species, C. carniolicum and C. greimleri. Hybrid status was confirmed for four morphologically intermediate individuals, found in the Ennstal Alps, Austria (three of them were F1 hybrids and one a backcross with C. carniolicum). We used amplified fragment length polymorphism (AFLP) to confirm affiliation to the parental species and exclude the potential contribution of other sympatric sp… Show more
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
