SARRACENIA VARIOLARIS. 



189 



From observa- 

 tions taken on the 

 ground where the 

 plants grew, I found 

 innumerable insects 

 were attracted to 

 them. The flaunting 

 yellow flower may lure 

 many moths and butter- 

 flies to the plant, but the 

 flower is not the attrac- 

 tion after they reach it. 

 This cord that runs along 

 the edge of the wing 

 secretes a sweet fluid, 

 and as the wing reaches 

 to the base of the leaf, 



insects that crawl on the ground as well as those that 

 fly are attracted to this sweet secretion. I noticed on 

 some of the plants a line of small ants extending from 



FIS. 19. — THE PITCHER-PLANT (SARRA- 

 CENIA VARIOLARIS).
