Acer hyrcanum is a maple species sometimes referred to as Balkan maple.[1] It grows in southeastern Europe and western Asia.[2]

Acer hyrcanum is a deciduous tree up to 15 meters (50 feet) tall. Leaves are up to 4 cm (1.6 inches) across, usually 5-lobed but occasionally with only 3 lobes, dark green on top, lighter green underneath because of a layer of wax.[3]
