Sequence data were obtained from Accepted 23 June 2015 nonindigenous N. minor populations in North America and portions of its native range in Europe (Italy) Available online 29 June 2015 and Asia (China, Korea). North American populations were mapped to evaluate the observed patterns of genetic variation geographically. We detected multiple genotypes of N. minor in collections originating Key words: from within Eurasia and North America.
