Formosan Nato Tree is a large evergreen plant up to 20 m high. A native plant in Taiwan, it can be found in northern, eastern, and southern coastal regions, as well as on offshore islands such as Orchid Island and Green Island. The bark is cracked and reddish brown in color. The leaves are oval or oblong and cluster at the ends of branches. The flowers are light yellow and cluster in the proximal leaf axil of young branchlets with six petals. The fruits when ripe have hard shells containing thick fibers that protect the seeds inside. The surface of the seed is smooth and impervious to saltwater, allowing it to travel long distances in seas and oceans in order to germinate in suitable environments. The plant can tolerate strong winds and excessive salt, making it capable of serving as a coastal windbreak. (Photo courtesy of Huang Yi-jun)
