Commercial value: The wood is hard and strong but coarse grained, and is used for construction timber, interior finish and furniture. It is inferior to white oak where strength and durability are required.

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.
