Comments

The Eurasian Carex disticha, thus far still a sporadic introduction, has been collected at two sites in Canada, both associated with ports on the Great Lakes-St. Lawrence system. A specimen to confirm a third, older report from near Belleville, Ontario, also on the Great Lakes, could not be located and verified (P. M. Catling et al. 1988).

Carex disticha

provided by wikipedia EN

Carex disticha is a Eurasian species of sedge known as the brown sedge[1] or, in North America, tworank sedge.[2]

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.[3] In its native range, this species is often associated with the Juncus subnodulosusCirsium palustre fen-meadow habitat.[4] Carex disticha has also been introduced to Canada, where it is known from only two sites, in Ontario and Quebec.[3][5]
