OAK FAMILY 



oring, like their spring coloring, is without red, being bright 

 3''ellow or yellowish brown. The acorns are peculiar, but 

 the cup is the most noticeable thing about them. The 

 scales are so large and free that they make the cup look 

 mossy. The rim is beautifully fringed. Then, too, this 

 mossy cup fairly embraces the nut, covers two-thirds to 

 three-fourths of its surface. This is the normal fruit ; at 

 the north where the tree changes to a shrub the acorn is 

 small and the cup loses its furbelows. 



The corky wings which are frequently found on the young 

 branches form a third distinguishing character. These ridges 

 begin to form usually the third or fourth season and remain 

 for several years, finally disappearing as the branches become 

 old. When it is remembered that the cork of commerce is 

 the outer bark of an oak tree native to southern Europe, it 

 is interesting to see a northern species showing a tendency 

 to produce the same thing.
