The collections of moss plants from the State of Iowa have been examined to such an extent that we feel warranted in making a statement of our present knowledge of the species of liverworts and their distribution in the State. While many collections of true mosses have not yet been examined, all of the packets known to contain liverworts have been studied, so far as known to us. It seems unlikely that any additional species will appear in the collections already made. Probably a few extensions of range will be found. This report will indicate the lacunae in our knowledge of distribution and the places where extensions of range may be expected. Where a species is absent from one county, but is known from all of the surrounding counties it is reasonably certain that it will be found in suitable places within the county for which it is not yet reported.
