tility, however, varying with topography an<l plant

 laden surface soil. Alluvial tracts are not, for the most part, 

 of great extent in the county, being limited by the narrow 



valleys. In the rougher part- Bandy and rocky tracts are

The investigations upon which this report is chiefly 

 were carried on largely during the Bpring, Bummer and fall of 

 1903. Every township in the county was visited, and 

 typical Localities were more thoroughly Btudied Thus M 

 and Ft. Atkinson were Belected for th< Btudy of the flora of the 

 rougher territory of the two principal river systems in the 

 southern part of the county; the vicinity of Calmer for the 

 southerly prairie, and Orleans township and Bluffton for that 

 in the western part of the county; for the rougher wooded region 

 the entire gorge of the Oneota was traversed a number of times 

 across the county, Decorah. Bluffton and Kendallville being the 

 main center- of investigation, while the hilly country bordering 

 Canoe creek and Bear creek received some attention; and the 

 vicinity of Eesper, with its woods and prairies, and unique 

 exposures of St. Peter sandstone proved the richest and most 

 interesting single locality in the county. 



The flora of this county had received some previous attention. 

 Arthur's "Flora of Iowa''* contain- numerous references to 

 plants from this county, which are based, at Least in large part. 

 on material furnished by Mrs. M. C. Carter of Hesper, and Mr. 

 E. \V. I>. Holway, formerly of Decorah; individual references 

 are also made to Winneshiek county plants by a number of other 

 authors who did not secure the material themselves, but n 

 it from others — chiefly from Mr-. Carter, and Messrs E. W. D. 

 Holway, Herbert B. Gtoddard, Thoa ES. Sa a Kbvarik,
