The writer spent the months of June and July, 1895, in this portion of Iowa, camping and traveling along Oneota or Upper Iowa and the Mississippi Rivers. While all available botanical specimens were collected special attention was given to the ferns and a good representation was secured. In the following year Mr. Herbert Goddard, then a resident of Decorah, Winneshiek County, sent the writer a collection he had secured in the vicinity of his home. During the years from 1899 to 1902 the writer had a valued correspondent, Mr. Ellison Orr, who resided at Waukon, Allamakee County. Mr. Orr's fine specimens were accompanied by many valuable critical notes. From these sources of information the following article has been written.
