 cranberry bogs, and the marsh rosemary {Andromeda polif olio) 

 with substantial evergreen leaves and revolute margins may be

In addition to the heatworts proper, there are of course a 

 large number of other plants which grow with them but such 

 species are rarely ever abundant enough to form a dominant 

 part O'f the flora. Second only to the heaths are likely to be the 

 representatives of the pea family — Baptisias, Cassias, Te- 

 phrosias, Desmodiums, Lespedezas and the like — that thrive in 

 sterile soil. Various grasses and sedges are usually present, 

 but the heathworts prove their right to the name by maintain- 

 ing their supremacy in the face of all competition.
