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 comparison with

other oaks. It develops a tall, straight trunk that tapers

continuously through a pyramidal crown of low, drooping 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 graceful tree and is

therefore extensively used for planting on lawns and on certain

streets where the tree can find plenty of water and where conditions

will permit its branches to droop low.



Commercial value: The wood is heavy and hard but coarse grained and

liable to check and warp. Its principal use is in the construction

of houses and for shingles.
