Poplar trees are generally 5 to 15 meters high, with white trunk, white or gray bark, rough base and wide crown.
Birch trunk can be as high as 25 meters, bark white smooth, like paper, can be layered off.
Poplar leaves have irregular tooth buds, petioles and leaves are equal or shorter, and the surface is covered with white villi. Leaves alternate, ovoid, 4 to 5 cm long, apex acute, base cordate, and margin microwaved, dark green above, pale green below.
The edge of the single leaf alternate leaves of birch has fine serration, which is thick paper, and the shape is triangular oval or triangular diamond. Leaves 3 to 9 cm long, 2 to 7. 5 cm wide, apex acute, base truncate, broadly cuneate or cuneate.
