Checker tree

Sorbus torminalis, with common names wild service tree, chequers, and checker tree, is a species of tree in the mountain ash or rowan genus (Sorbus) of the rose family (Rosaceae), that is native to Europe, parts of northern Africa and western Asia. It is a medium-sized deciduous tree growing to 15–25 meters (49–82 feet) tall, with a trunk up to 1.3 m in diameter. The bark is smooth and grayish, but flaky, peeling away in squarish plates to reveal darker brown layers. The leaves are 6–14 centimeters long and broad with a 2.5–5 cm petiole, dark green on both sides.
