Quercus alba, the white oak, is one of the preeminent hardwoods of eastern and central North America. It is a long-lived oak, native to eastern and central North America and found from Minnesota, Ontario, Quebec, and southern Maine south as far as northern Florida and eastern Texas. [3]
The cup (cupule) at the base of the acorn has scales with sharp angled ends. The leaves are either evergreen or deciduous, with simple or compound teeth. The leaf buds are large, enclosed in loosely attached scales. [2] There are only two species, Quercus pontica and Quercus sadleriana. [5] They have disjoint distributions.
The bark resembles that of the white oak. The leaves are broad ovoid, 12–18 centimetres (4 + 3 ⁄ 4 –7 inches) long and 7–11 cm (2 + 3 ⁄ 4 – 4 + 1 ⁄ 4 in) broad, always more or less glaucous on the underside, and are shallowly lobed with five to seven lobes on each side, intermediate between the chestnut oak and the white oak.

A hybrid white oak, possibly Quercus stellata × Q. muehlenbergii. Interspecific hybridization is quite common among oaks, but usually between species within the same section only, [44] and most common in the white oak group. White oaks cannot discriminate against pollination by other species in the same section.
Quercus robur (from the Latin quercus, "oak" + robur derived from a word meaning robust, strong) was named by Carl Linnaeus in Species Plantarum (1753). [11] [12] It is the type species of the genus and classified in the white oak section (Quercus section Quercus). [13] It has numerous common names, including "common oak", "European oak" and ...
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 ...
Key characteristics of Quercus muehlenbergii include: [7] Leaf base is typically rounded [2] Veins and sinuses are regular [2] Acorns with no stalks or with short stalks less than 8 mm long. The acorns turn chestnut brown in the fall [2] The leaves have sharp teeth but no bristles, as a member of the white oak subgenus of Quercus [2]
Oregon white oak is the only native oak species in British Columbia, Washington, and northern Oregon. In these areas, oak woodlands are seral, or early- successional ; they depend on disturbance to avoid being overtaken by Douglas-fir ( Pseudotsuga menziesii ).
