Status/Listing: Formerly State Endangered, Extinct, Misidentified

Notes:Accordng to Ebinger et al. 2010, this species was either never located here or it is now extirpated, "Voucher not located. (State Endangered) Native to the northeastern United States and adjacent Canada, this edge has been reported from Pope County by Mohlenbrock (2002a). Crins and Rettig (2002) in the ‘‘Flora of North America’’ did not report this species for Illinois. Mohlenbrock (1999a) lists the following specimen (Pope Co) that we have been unable to locate (Mohlenbrock 2009). It is presently listed as an Illinois endangered species (Herkert and Ebinger 2002). If no voucher is found, Carex lucorum should be removed from the endangered species list."
