The newly described diploid species Cirsium greimleri (2n = 34; 2C = 1929.1±60.6 Mbp) belongs to Cirsium sect. Cirsium and is distributed sparsely throughout the Eastern Alps and Dinarides, whereas the closely related tetraploid vicarious species C. waldsteinii (2n = 68; 2C = 3682.3±69.8 Mbp) is endemic to the south-eastern Carpathians. The ploidy, genetic and morphological separation of both taxa is confirmed using flow cytometry, AFLP and morphometric analyses of 169 plants from 27 populations covering repr…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
