THE FLOEA OF THE EAINY EIVER REGION. 
HARRIETTE S. KELLOGG. 
There is no evidence accessible to the writer that a critical 
study of the flora of this region has ever been made, although 
several of the early explorers must have passed over this part of 
Minnesota. 
Mr. Warren Upham^ mentions the work of Mr. Thomas Say 
who was with Long’s expedition. Keating noted in 1823, that 
Say had collected from the vicinity of the Lake of the Woods and 
along Rainy Lake as far as the Lake Superior region, thirty of 
his plants being from the Minnesota side. 
The report of the British North American Boundary Commis- 
sion submitted by Mr. George Dawson and published in 1875 
includes flora from the Lake of the Woods to the Red River and 
lists 289 plants from Minnesota. Both of these reports would 
necessarily include many plants indigenous to the Rainy river 
country. 
Mr. John Macoun later surveyed the whole of the Dawson 
route, his work being recorded in the ‘‘Catalogue of Canadian 
Plants” published in 1883 under the Geological and Natural 
History Survey of Canada. 
Conway Macmillan’s “Metaspermae of the Minnesota Talley” 
covers the southern part of Koochiching county, then a part of 
Itasca county. 
The ‘ ‘ Observations on Distribution of Plants along th-e Shores 
of the Lake of the Woods”, by the same author, has been help- 
ful as a means of comparison with the notes made in the col- 
lecting tour described in the present paper. 
The territory to which reference is made in the following 
study lies below Koochiching or International Falls on the south 
bank of the Rainy river, and on both sides of the “Old Dock” 
in the city of International Falls, Minnesota. Plants were col- 
lected from an area extending about forty feet east of the dock 
in the timbered belt only, but west of the dock, the survey ex-
