It is a tree imported from Mainland China.  Leaves are broad, leathery hard, bearing a bitter taste, hence also called the 'bitter tea' in Chinese.  Dioecious, flowers are yellowish-green with a four-lobed corolla.  Fruit is drupe that reddens when ripe.  The plant has been first introduced to the territory by CUHK for its medical leaves, which can be used together with leaves of the Chinese Holly and Rough-leaved Holly to treat flu (a Trilex formula).  This is an important discovery by Dr. X.Y.
