Carex disticha
Introduction '''''Carex disticha''''' is a Eurasian species of sedge known as the '''brown sedge''' or, in North America, '''tworank sedge'''.
Distribution ''Carex disticha'' is native to parts of Northern and Western Europe, where it grows in moist spots in a number of habitat types, and it has been introduced to the Great Lakes region of southern Canada. In its native range, this species is often associated with the ''Juncus subnodulosus''–''Cirsium palustre'' fen-meadow habitat. ''Carex disticha'' has also been introduced to Canada, where it is known from only two sites, in Ontario and Quebec.
