MOUNTAIN CRANBERRY 



Vaccinium vitisidaea minus Loddiges 



FRUIT OF PLATE 1 93 



The fruit of the mountain cranberry is sour, but it is relished by 

 birds, and its beautiful red color always attracts the eye. Where con- 

 ditions of moisture and soil acidity are favorable the stems cover the 

 ground in dense mats, and the berries attain twice the size of those 

 on plants found in dry, sterile situations. 



The mountain cranberry grows throughout the colder parts of 

 North America, its southernmost known station being in northeast- 

 ern Massachusetts. 



The specimen sketched was procured in the valley of the Siffleur 

 River, fifty miles north of Lake Louise, Alberta, at an altitude of 4,000 

 feet.
