Quercus infectoria, commonly known as the Aleppo oak, is a species of oak tree native to Greece, Asia Minor, and Iran. This deciduous tree is part of the Fagaceae family and is notable for its small to medium size, typically reaching heights of 5 to 10 meters. The leaves of Quercus infectoria are simple, lobed, and measure about 3 to 7 centimeters in length. They exhibit a dark green color on the upper surface and a lighter green on the underside.One of the most distinctive features of Quercus infectoria is its production of galls, which are abnormal growths that occur on the tree in response to the activity of certain insects, particularly gall wasps. These galls are rich in tannins and have been historically used for their medicinal properties and in the tanning of leather.The bark of the Aleppo oak is rough and deeply fissured, providing a habitat for various forms of wildlife. The acorns produced by this tree are small, typically about 1 to 2 centimeters in length, and serve as a food source for numerous animals.Quercus infectoria thrives in well-drained soils and can be found in a variety of habitats, including woodlands, scrublands, and rocky slopes. It is a resilient species that can tolerate drought conditions and poor soil quality, making it an important component of the ecosystems in which it is found.
