Wide speculation surrounds the origin and phylogenetic relationships of the most highly reduced sections in the genus Carex. In order to gain a better understanding of phylogeny in Carex, the relationship of the reduced sect. Phyllostachys to 12 putatively related sections, representing all four subgenera (Primocarex, Indocarex, Carex, Vignea), was inferred(More)
Carex species are dominant and abundant plants in boreal and arctic landscapes, typically covering large wetland areas. Most of these vegetation-characteristic species are from Carex sections Phacocystis and Vesicariae, frequently growing together, but also forming monodominant stands. Here we study these species in a phylogenetic framework to infer whether(More)
Although the polyphyletic genus Scirpus L. s.l. (formerly > 200 species) has been divided into more than 50 separate genera and now consists of only 64 species, its circumscription remains problematical. Three new genera have been segregated from Scirpus s.s. in the past decade, and the delimitation of Scirpus from its possible sister genus Eriophorum L.(More)
