AMERICAN MIDLAND NATURALIST 



Linnaea americana Forbes is regarded a decidedly more 

 northern plant than would be expected in our flora. Its presence 

 in a bog at the lower end of Lake Michigan near Mineral vSprings 

 (Porter Co.), where I found it this fall, may be accounted for by 

 the fact that the prevailing cold winds from the north that built 

 the dunes make the region somewhat boreal. Other more northern 

 plants associated with it are Cornus canadensis Linn, and Thuja 

 occidentalis Linn. Of the latter there are still some trees over 

 twelve inches in diameter, and a rather good growth of saplings. 



For Apocynmn tomentcllum Nwd. Am. Mid Nat. III., p. 55, 

 substitute Apocynum iomentidosmn. There was another plant 

 of that name, Greene E. L. Leaflets etc. Vol. I. p. 58.
