The following notes are the result of a series of studies made during the summer of 1895 when the writer passed down the Upper Iowa River from Decorah to its mouth and thence down the Mississippi River to Muscatine, examining en route the floras of Winneshiek, Allamakee, Clayton, Dubuque, Jackson, Clinton and Scott Counties. Much field work was done by collecting specimens and taking notes. The writer received aid subsequently in the examination of a collection from Winneshiek County made by Herbert Goddard of Decorah, Iowa. All the rare or infrequent species mentioned in the following list are represented in my herbarium. Those common as Quercus alba, Ulmus americana, Populus monilifera, Xanthium canadense, etc., are not represented by specimens from all the localities given.
