Quercus pontica, the Pontic oak or Armenian oak,[1][2][3] is a species of endangered oak in the family Fagaceae.[4][5] It is currently extant to the western Caucasus mountains of Georgia and northeastern Turkey where it grows at altitudes of Template:Convert.[6]

Description

Quercus pontica is a deciduous small tree or large shrub growing to Template:Convert tall, with a trunk up to Template:Convert in diameter and sparse, stout shoots. Its bark is greyish to purple-brown, smooth on young trees but becoming rough later in its life. Its leaves grow to Template:Convert long, rarely 35 cm, and 4–15 cm across. They are ovate, and have a serrated margin with numerous small, pointed teeth. The leaves are covered in hairs when they are young, but become smoother as they age. They become bright green later in life and turn yellow brown in autumn. The flowers are catkins, the male catkins 5–20 cm long. The fruit is a large acorn 2.5–4 cm long, produced in clusters of 2–5 together.

Taxonomy

Cultivation

It is occasionally grown as an ornamental tree in northern Europe.
