Bauhinia is an interesting tree. It is not tall, but its shape is very special. The pandanus tree has a column root similar to a mangrove forest. The leaves of the pandanus tree are banded, more than 1 m long, with sharp serrations on both sides of the leaves and the midvein on the back. Anyone who dares to rub his hand on these serrations will definitely cut his hand. Stinky peony is a living fossil of plants. Its origin can be traced back to the ice age, and its leaves, roots and fruits have certain medicinal value. Fruit is the drop of blood after knife work, and it is the best of bodhi.
