Water oak
Quercus nigra
Water oak is a bottomland species that will also grow on upland sites. Its leaves are variably shaped but usually exhibit three indistinct lobes. The tree is easily damaged or killed by fire. On good sites the tree has a slender, straight trunk and can occasionally reach heights of 100 feet or more. Its acorn is small and almost black in color, often a half-inch or less in length. Its wood is not considered very suitable for finished lumber.
Water oak has deciduous leaves that are small, 2 to 4 inches long, and much more broad at the apex than at the base.
