Aucuba species are native to eastern Asia, from the eastern Himalaya east to Japan. They are evergreen shrubs or small trees 2-13 m tall, similar in appearance to the laurels of the genus Laurus, having glossy, leathery leaves, and are sometimes mistakenly called laurels.
The leaves are opposite, broad lanceolate, 8-25 cm long and 2-7 cm broad, with a few large teeth on the margin near the apex of the leaf. Aucubas are dioecious, having separate male and female plants. The flowers are small, 4-8 mm diameter, with four purplish-brown petals; they are produced in clusters of 10-30 in a loose cyme. The fruit is a red berry 1 cm diameter.Species Three species (A. chinensis, A. himalaica, A. japonica) have traditionally been accepted, but the recent Flora of China accepts ten species:
