Oak galls are excrescences that are sometimes produced in great numbers on the tree and are caused by the activity of the larvae of different insects. The insects live inside these galls, obtaining their nutrient therein. When the insect pupates and leaves, the gall can be used as a rich source of tannin, that can also be used as a dyestuff. The seed cups are used as buttons.Wood - hard, heavy, close-grained. The trees are generally too small to be of use commercially, though the wood is used locally for lumber and also makes a good fuel.
