WINTERGREEN FAMILY 
PYROLACEE 
UNTIL quite recently, and even yet in some 
books, this family is treated as a part of the great 
Heath family, but is sufficiently distinctive to 
a I al 
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.
