of low, marshy ground." Of LaPorte County': "The central and southern parts 

 are mostly prairie;" and only", "small marshy spots and peat-bogs" to the 

 north. Marshall County. is spoken of in another report by AV. H. Thompson' as 

 mostly prairie and large tracts of barren land. 



These references to gmall percentage of lakes, swamps and bogs from these 

 northern counties not in the lake region under discussion, when compared with 

 the continued references, everywhere, to the large percentage of such conditions 

 in the northeast Indiana lake region, would seera to be sufficient authority for 

 separating it from the "lake region," as formerly considered. 



OUTLINE OF THE BOTANICAL WORK DONE IN THE REGION. 



A Flora of Steuben County was published in 1892 by E Bradner^", and a 

 Flora of Noble County in 1893 by W. B. Van Gorder' ^. So far as I can ascertain, 

 no geological report has ever been made for Kosciusko County, and no specimens 

 of plants preserved, other than those in my herbarium. 



In company with Prof. A. B. Crowe, of Ft. Wayne, and Thomas A. Davis, 

 of Goshen, I made a short collecting trip through the lakes and marshes in the 

 northeastern part of Kosciusko County, during the last of June and the first of 

 July, 1894; and I have made collections in the more immediate vicinity of 

 Warsaw since 1893. 



During the summer of 189() I spent several weeks in the study of the grasses 

 and sedges of the immediate vicinity of Warsaw, under Dr. Stanley Coulter, but 

 owing to rains and floods making it impossible to get to desirable low regions, 

 and to the fact that I was limited to a part of each day by other work, I was able 

 to collect and study but some forty species. 



I may say that it is at the suggestson of Dr. Coulter that I attempt this paper. 



The Floras of the two counties mentioned, and my own collections will be re- 

 ferred to as a basis for deductions, since the three counties thus covered will com- 

 prise the greater part of the region, and no reports of the botony of the other 

 counties— only small parts of which are included in the region — have been made. 



GENERAL PHYSIOGRAPHIC CONDITIONS. 



The climate throughout the region is the same; there being only about forty 

 miles difference in latitude and sixty miles in longitude. The general surface of 

 the country is rolling, and almost hilly to the north, sloping in general to the
