gards its denticulations: equally toothed (cequaliter 

 dentatus), 34 ; unequally toothed (incequaliter den- 

 tatus), 35 ; deeply toothed (profunde dentatus) ; 

 obscurely toothed (obsolete dentatus), 36. If the 

 denticulations themselves be again dentated, then 

 the margin is termed doubly dentate (duplicato- 

 dentatusj, 37. 



The margin is denominated serrated (serratus), 

 38, when the teeth are sharp, and lie as it were 

 upon each other, as in a saw, all pointing towards 

 the apex of the leaf. The nature of the serratures 

 is distinguished by the following terms applied to 

 the margin : equally serrated (cequaliter serratus); 

 unequally serrated (incequaliter serratus); sharply 

 serrated (argute serratus) ; deeply serrated (pro- 

 funde serratus), 3Q; and doubly serrated (du- 

 pUcato-serratus), 40. When the serratures are 

 minute, or not distinct, the margin is termed 

 serrulatus, 41.
