Tetradium

Tetradium is a genus of about 5 to 10 species of trees in the family Rutaceae, occurring in temperate to tropical east Asia. In cultivation in English-speaking countries, they are known as Euodia (or sometimes Evodia), from the name of the genus Euodia that they used to be treated in.

They are attractive ornamental trees with glossy pinnate leaves, particularly valued for their clusters of white flowers produced in late summer when few other tree-size plants are flowering. For the same reason, they are also highly valued by beekeepers for their late season nectar. The small, red-to-black berries follow in late autumn and are popular with many birds.

The genus is closely related to Melicope and is sometimes included within it.
