Flour trees generally grow in shady barns, mainly distributed in South China. They can grow to more than ten meters high. Under normal circumstances, the diameter of an adult tree is 1 m, and its leaves are generally about 1 m wide and about 3 meters long, which are very similar to banana leaves.
If the skin of a flour tree is dried in the sun and then ground into powder, tree powder is obtained. It looks just like ordinary flour. Locals will use it to make pancakes and rinse them with boiling water.
