This smallish family, containing five genera¹, is almost confined to the northern hemisphere in both the Old and New World, overstepping the equator only in Ecuador and Peru in S. America and in Malaysia, where it is found southward to Java and New Guinea. Among the genera Huertea is confined to Peru and the West Indies (Cuba, Haiti). Tapiscia and Euscaphis are East Asian. Staphylea is widely distributed in the subtropical and temperate zone on the northern hemisphere. Turpinia is subtropical and tropical, it is the only genus represented in Malaysia. It is remarkable that the distributional areas of the latter two genera seem to exclude one another save for a slight overlapping in SE. Asia.
