Conard (1945) in his comprehensive study of the Bryophya of Iowa lists five species of Sphagnum, collected in four widely separated counties. Four of the species were collected in two counties each and one was collected in a single county, Linn. Four species were reported from Linn county, two from Muscatine, and one from Clayton and Warren counties. Since the publication of this report other collections have been made which indicate that the genus is more generally represented in the Iowa flora, especially in that of eastern Iowa.
