WINTERGREEN FAMILY 



PYROLACE^ 



Until quite recently, and even yet in some 

 books, this family is treated as a part of the great 

 Heath famil}-, but is sufficiently distinctive to 



ONE-FLOWERED PYROLA 



stand by itself. Several members of the group 

 are shrubs while the others are evergreen herbs. 

 The petals of the corolla are not united to each 

 other and the calyx is free from the ovary. There 

 are many seeds in the fruit.
