In North America, most authors have followed K. K. Mackenzie's (1931-1935) arrangement of the genus, in which he did not recognize subgenera and instead divided the North American Carex into 71 sections. The sections were narrowly defined, for the most part consisting of groups of species that were very similar morphologically.
