Iteaceae is a flowering plant family of trees and shrubs native to the eastern USA, southeastern Africa, and south and Southeastern Asia. Some older taxonomic systems place the genera in this family in the Grossulariaceae. The APG III system of 2009 includes the former Pterostemonaceae in Iteaceae. It consequently now has two genera with a total of 18 known species.
