THE OAKS AND CHESTNUT 



79 



PIN OAK (Quercus palustris) 



Distinguishing characters: Its method of branching 

 will characterize the tree at a glance. It develops a well- 

 defined main ascending stem with numerous drooping side 

 branches as in Fig. 63. The buds 

 are very small and sharp pointed 

 and the leaves are small as in 

 Fig. 64. The bark is dark, firm, 

 smooth and in close ridges. The 

 acorn is small and carries a light 

 brown, striped nut, wider than 

 long and bitter. The cup is 

 shallow, enclosing only the base 

 of the nut. 



Form and size: The pin oak 

 is a medium-sized tree in com- 

 parison with other oaks. It de- 

 velops a tall, straight trunk that 

 tapers continuously through a 

 pyramidal crown of low, droop- 

 ing tender, branches. 



Range : Eastern North 

 America. 



Soil and location : It requires 

 a deep, rich, moist soil and grows 

 naturally near swamps. Its roots are deep and spreading. 

 The tree grows rapidly and is easily transplanted. 



Enemies: None of importance. 



Value for planting : The pin oak is an extremely grace- 

 ful tree and is therefore extensively used for planting on
