NOTES ON THE FLORA OP NORTHEASTERN IOWA. 



BY T. J. FITZPATRICK. 



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 enroute 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 subse- 

 quently 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, 

 Vlmus americana, Popular monilifera, Xanthium canadense, etc., 

 are not represented by specimens from all the localities given 



The difficult species have been carefully compared with 

 specimens in the herbarium of the State University of Iowa, or 

 submitted to competent botanists. The sedges were determined 

 by R. I. Oratty, the grasses by F. Lamson-Scribner, and 

 miscellaneous species by the officers of the Missouri Botanical 

 Garden at St. Louis. The writer hopes the following notes 

 may be beneficial to students who study the flora of that por- 

 tion of the state, a flora unique in many respects.
