Species of medium-sized oak tree native to the western coast of North America, from British Columbia to southern California. Particularly common in the Willamette Valley, it hosts gall wasps and mistletoe.

A small to medium-sized, long-living evergreen oak found mostly in cold semi-arid to temperate humid regions of the Mediterranean basin. It has small leathery and wooly leaves with an upper side of dark green, and a lower side covered in white hairs. The wood of the tree is dense and semiporous, and is often used as firewood. Its acorns have been used to feed livestock.

Species of medium sized oak tree growing to 20 meters in height, native primarily to the Midwestern and southern United States, typically growing in uplands with good drainage, but occasionally at lowland streams. Its leaves are shaped like laurel leaves. The fruit is an acorn that is an important food source for squirrels and birds. The common names comes from its use in making making shingles and clapboard siding for houses.

Species of oak native to the Near East; important source of nut galls, abnormal growths caused by a wasp and which contain tannins sued for leatherwork, making ink, and in medicines to treat burns.

Species of small, slow-growing deciduous shrubby tree native to the dry, sandy areas of the southeastern United States, on the coastal plain from Delaware to Florida and Louisiana. It reaches 10 meters in height, has deeply incised leaves with 3-7 slender lobes, and acorns that take 18 months to mature. It hybridizes easily with southern red oak (Q. falcata), bluejack oak (Q. incana), laurel oak (Q. laurifolia), and water oak (Q. nigra). Its name "turkey oak" is derived either from the turkey-footprint shape of its leaves or from the fact that wild turkeys eat the acorns.

Species of medium sized oak tree native to the southeast of the United States, from coastal Virginia to central Florida to Texas, growing 20-25 m (65-80 feet) in height, and having a large, circular crown.

Species of ornamental and shade tree, often 30 meters (100 feet) in height, having graceful, drooping branches, many-lobed dark green leaves, and large, distinctive acorns about 5 cm (1.7 inches) long. The ash-gray to light-brown bark, slightly orange-tinted, is fissured in irregular cubes.

Species of medium-sized oak tree native to lowland wetlands in the southeastern United States, from Delaware and southern Illinois south to northern Florida and southeast Texas. The common name refers to the acorn almost completely enclosed by the cup or its scale. The Latin name comes from the shape of the leaves, which resemble a lyre.

Species of white oak timber tree native to North America, found in eastern and midwestern United States and south-central Canada. It is also called "mossy-cup oak" for its heavily fringed acorn cups. It is a popular ornamental and shade tree in urban areas because of its resistance to insect and fungal attack, drought, and air pollution. Previously common in oak savannas and prairies, the tree is well adapted to fire with its corky, fire-resistant bark.

Species of oak tree native to the southern Mediterranean, Morocco, and Asia Minor. The tannin extracted from the large acorn cups was used in the 18th century for tanning leather and for dyeing. The acorns, themselves called "valonia," are edible.

Species of valuable North American bottomland timber tree of the Atlantic and Gulf coastal plains and Mississippi Valley region, growing 24-36 meters in height, with branches rising at narrow angles from a columnar trunk to a round, compact head. It has silver-white, red-tinged bark and bright green, glossy leaves, velvety and whitish beneath, usually 20 cm in length and turning red in autumn. Swamp chestnut oak is often called "cow oak," because the acorns are eaten by cattle, or "basket oak" from local use of the wood strips for basket material. It was formerly considered a variety of Q. prinus ("rock chestnut oak" or simply "chestnut oak"). Q. michauxii is typically more massive than Q. prinus. A quick way to distinguish the two species is by habitat; if the tree grows on a ridge, it is probably Q. prinus; if it grows in wet bottomlands, it is probably Q. michauxii.

Species of spreading oak tree that is native to North American, in the greater Midwest, ranging downward to the deep South and over into the eastern edge of the Great Plains of the U.S. When in the open, it grows to 60 feet in height by 80 feet in width, often with wide-spreading lower branches of great diameter. Chinquapin oak prefers moist, well-drained, deep, rich, alkaline soils, but is often found near the summit of hills or uplands in dry soils that may be rich, clay, sandy, or rocky. It also tolerates neutral to acidic soils. It thrives in full sun to partial sun (but is shade tolerant in youth).

Species of tall, pyramidal tree native primarily to bottomlands and moist uplands of eastern North America, but found as far west as Oklahoma and Ontario, Canada. It is distinguished by having clusters of short, spiky twigs and leaves with bristle-tipped lobes, thus accounting for the common name "pin oak."

Species of large deciduous oak tree, growing to 20-40 meters in height; native to most of Europe and Anatolia . It is similar to Quercus robur (pedunculate oak), with which it overlaps extensively in range.

Species of small tree or shrub that forms dense thickets; it is a useful cover plant on dry, rocky ridges. It resembles chestnut oak (Quercus prinus); however, it is more closely related to chinkapin oak (Quercus muhlenbergii).

Refers specifically to the wood of the species Quercus prinus (also called Q. montana), used in making furniture. The term "chestnut oak" is also used informally as a general term referring to any of several species of oaks having leaves similar to chestnut trees.

Species of large oak tree native to most of Europe, Anatolia, the Caucasus, and parts of North Africa; growing 25-40 meters in height, and having a bark that is grayish brown in color and having deep fissures with aging. The tree is valued for brown wood with a coarse but straight grain. The bark is used for tanning and dyeing.

Species of oak native to northeastern United States and southeast Canada, but found north in Nova Scotia, south to Georgia, and west to the Great Lakes. It is used for timber but often cultivated as an ornamental; it grows rapidly into a round-headed, wide-spreading tree about 25 m (80 feet) in height, with leaves that turn red-orange in autumn and persist into winter.

Species of large oak native to the Atlantic Coastal Plain of the U.S., in the Mississippi and Ohio river valleys. It is also found in Michigan, Pennsylvania, Maryland, and Ontario, Canada. It is used for shade, for timber, and the acorns and leaves are food for various birds and mammals.

Hard, close-grained, durable wood of the species Quercus stellata, native to sandy soils of the central and southern United States. It is tough and rot-resistant, used for fence posts, rough construction, and as a fuel for barbequing meat.
