Betula platyphylla Suk: a deciduous tree with a trunk up to 25 meters high and 5 centimeters thick. There are white smooth paper-like bark, which can be peeled off in layers, and you can write on the thin bark with a pencil. The leaves of Betula platyphylla are simple and alternate, with serrated edges. The flowers are unisexual and monoecious, and the male inflorescence is soft and drooping. The leaves on the tree bloom before they grow out in spring. The fruit of birch is flat and small, called samara, which is easily blown up by the wind and spread far away.
