Quercus macranthera aka Caucasian Oak

Quercus macranthera, also known as the Caucasian oak or Persian oak, is a slow-growing, large deciduous tree native to Western Asia, including northern Iran, Turkey, and the Caucasus region in Georgia, Armenia, and Azerbaijan. This tree, occasionally cultivated as an ornamental tree in Europe, can reach heights of up to 30 meters (98 feet). It features large, dark green leaves with regular rounded lobes along the edges, measuring up to 15 centimeters. The leaves have a grey, downy underside and turn dark yellow-brown before falling. The Persian oak has a high domed crown and thin bark that flakes off in large sheets. Its shoots are thick and covered in gray tomentose hairs, which shed in the second year. The tree's buds are adorned with permanent, thread-like stipule scales. The obovate leaves, measuring 8 to 20 centimeters in length, have a rounded tip and narrowed base. They are regularly flat-lobed, with 7 to 11 rounded, egg-shaped lobes on each side, with seven to eleven pairs of nerves formed. The upper side of the leaf is almost hairless and dark green, while the underside is hairy, ranging from gray to yellowish tomentose. The tree produces egg-shaped-ellipsoid fruits, approximately 2.5 centimeters long, which are half surrounded by a hemispherical fruit cup adorned with lanceolate, upright, or splaying scales.
