Endemic to Taiwan, Kawakami Excoecaria grows in coastal areas and is mainly distributed in Lanyu Island and Green Island. Thanks to the smooth, thick, hard and leather-like leaves, the tree is highly tolerant to wind, salt, and drought, therefore, it can serve as windbreaks or hedges in coastal areas. It has two patterns of flowering - monoecious or dioecious which can only be distinguished when flowering. The ranches and leaves will secrete white milk and accidental touching may cause skin irritation or itching. The wood emits fragrance when burned and can be a substitute for agarwood. The Yami people settled on Lanyu often hang branches of the tree on their chests to exorcise demons.
