Distribution.—Maine, southern Ontario, southern Minnesota south to Georgia and Arkansas. Found in all parts of Indiana. It is always found in wet places. In most of its range it is associated with the bur oak from which it is not commonly separated. In the northern counties it is usually associated with pin and bur oak, and white elm; in the flats of the southeastern part of the State it is usually associated with cow oak and sweet gum, while in the southwestern counties it is found most commonly with Spanish and pin oak.
Remarks.—Commercially the wood is not distinguished from white oak, and the cut is sold for that species.
