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 …

Taxonomists have proposed numerous hybrid species in plants, but to gain a better
understanding of the role that hybridization may play in plant diversification, such taxonomic …
