A STUDY OF LEAVES. 



35 



To study the relation of leaves to one another, 

 cut off the top of the bud and examine the cut 

 edges with a magnifying- glass. It will be found 

 that they are either folded so that the edges barely 

 touch, when they are called valvate ; or the edges 

 overlap like the coats of an onion, when they are 

 called imbricate. 



When leaves continue to overlap at the base 

 after they have developed, they are equitant. 



Equitant.
