Silver birch, Abedul común

Medium-sized deciduous tree, 15–25 metres tall with a crown of arched branches with drooping branchlets. The bark is white, often with black diamond-shaped marks or larger patches, particularly at the base. The flowers are wind-pollinated catkins, produced before the leaves in early spring, the small 1-2mm winged seeds ripening in late summer on pendulous, cylindrical catkins 2–4 centimetres.
