It is a remarkable fact, that the family of Caryophyllaceaa, so extensive in 

 the alpine regions of Europe, has so few representatives about Lake Superior. 

 The reason is, that the Caryophyllacefe, like the Cruciferte, belong for the most 

 part, to the alpine flora properly, and to the flora of the plains, and are missing 

 in the subalpine, or intermediate regions. 



* A small species of Draba with yellow flowers, found at Michipicotin, was lost.
