Back strand formations at Lake of the Woods may be in- 

 structively classified into three general groups: 



I. Herbaceous back strand. 

 II. Shrubby back strand. 

 III. Arboreal back strand. 



Each of these main types may be subdivided as one or another 

 variety of plant gives the characteristic appearance to the 

 formation as a whole. Yet there are not so many principal 

 types as one would suppose. The following synopsis brings 

 out what I think are the principal and most important sub- 

 groups. 



I. Herbaceous back strand. 



a. Gramineous back strand. 



b. Mixed herbaceous back strand. 

 II. Shrubby back strand. 



a. Coniferous back strand. 



b. Populus back strand. 



c. Sato back strand. 



d. Cerasus and Rosa back strand. 

 c. Mixed shrubby back strand. 



III. Arboreal back strand. 



a. Coniferous back strand. 



b. Populus back strand. 



c. Salix back strand. 



d. Ouercus back strand. 



e. Mixed arboreal back strand.
