flowers to be found? 
How does their time of appearance compare 
with that of the Hepatica, Dog’s-tooth 
Violet and Mayflower?

two kinds of blossoms differ in any way. 
What insects visit the flowers? 
Where is the nectar secreted? 
How does the plant prevent ants from steal- 
ing the nectar?

the flower?

the flowers?
