The Malvaceae are generally plants of warm countries. This family is not 

 represented about Lake Superior by a single species, nor are the intermediate 

 families between this and the Leguminosse. The Leguminosse themselves are 

 very rare, since they are, like the Caryophyllaceaa, plants of the higher Alps, or 

 of the plain. The Rosaces, on the contrary, generally extensive in the sub- 

 alpine regions of Europe, are also abundant around Lake Superior.
