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

nut.
