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).
