The angles the secondary veins make with the midrib. 



(We shall have much to say on the subject when we come to Mature Leaves 



in the next Part.) 



a. Normal Species. — In an orbicular leaf, of which most juvenile leaves consist, 

 it is obvious that the venation, from the base to the apex, varies most widely. At the 

 apex the secondary veins may vary from about 75 deg. at the base, to about 30 deg. 

 towards the apex. In dealing under " Mature Leaves," in recording the angles I 

 have dealt with the middle third of the leaf; there is less necessity for this in dealing 

 with " Juvenile Leaves," as I am at present. 



In many cases we do not know whether we have the earliest juvenile leaves or 

 not, although we have in juvenile leaves frequently the assistance of the seedling series, 

 assistance we do not receive in regard to mature leaves.
