Oak-hickory, beech-maple, and mixed hardwood stands; in the northern Lower Peninsula, often with jack pine and other oaks on sandy plains.
A familiar tree, the white oak is easily recognized by the rounded lobes and definite sinuses of the leaves, which are pale and completely glabrous beneath. (The dense pubescence on both surfaces of the young leaves is readily deciduous; rarely a few hairs may persist along the midrib beneath, but these are easily dislodged.) This is an important timber tree farther to the south and east, but it is not of so much commercial importance in Michigan.
Hybrids with several other species are known in the state. Most common is Q. ×bebbiana C. K. Schneid. (Q. alba × Q. macrocarpa); also known are Q. ×jackiana C. K. Schneid. (Q. alba × Q. bicolor), Q. ×faxonii Trel. (Q. alba × Q. prinoides) and Q. alba × Q. muehlenbergii, for which no scientific name is available since Q. ×deamii has been found to be Q. macrocarpa × Q. muehlenbergii.
