Quercus alba is sometimes confused with the swamp white oak, a closely related species, and the bur oak. The white oak hybridizes freely with the bur oak, the post oak, and the chestnut oak. [5] Detailed description. Bark: Light gray, varying to dark gray and to white; shallow, fissured and scaly.
Quercus ajoensis C.H.Mull. – Ajo Mountain shrub oak, Blue shrub oak – Arizona, New Mexico, Baja California; Quercus alba L. – white oak – eastern and central North America; Quercus aliena Blume – Oriental white oak – eastern Asia; Quercus alpescens Trel. – Mexico; Quercus ariifolia Trel. – Mexico; Quercus arizonica Sarg.
Quercus bicolor, the swamp white oak, is a North American species of medium-sized trees in the beech family. It is a common element of America's north central and northeastern mixed forests. It can survive in a variety of habitats. It forms hybrids with bur oak where they occur together in the wild.

Quercus stellata, the post oak or iron oak, is a North American species of oak in the white oak section. It is a slow-growing oak that lives in dry areas on the edges of fields, tops of ridges, and also grows in poor soils, and is resistant to rot, fire, and drought. Interbreeding occurs among white oaks, thus many hybrid species combinations ...
Northern red oak is the most common species of oak in the northeastern US after the closely related pin oak (Q. palustris). The red oak group as a whole are more abundant today than they were when European settlement of North America began as forest clearing and exploitation for lumber much reduced the population of the formerly dominant white ...
Scarlet oak is prominent as a co-component of forests, including species such as white oak, black oak, and northern red oak. When at a lower elevation surrounding the Appalachian Mountains, pine forests and heaths are a common component. Oak seeds are faster-growing than many other trees and can compete very successfully.
The red oaks of Mexico are one of the groups of oaks that have most rapidly diversified into different species. Molecular evidence suggests that there are significant numbers of undescribed Quercus species in Mexico, so the number of known species in the section is likely to be an underestimate of the total diversity.
