This list was originally produced by John A. Christy in 1989 and based on the county distribution maps from Bowers and Freckmann (1979). Since then, it has been augmented by literature found after that publication, holdings at the Milwaukee Public Museum Herbarium (MIL), and one specimen housed at the Chicago Academy of Sciences (Splachnum ampullaceum). Examination of herbarium collections elsewhere may yield other species.
