As shrubs, they are twine climbers or tendril climbers, and rarely root climbers.

The family, cosmopolitan, is present in both the Old World and the New World, with Catalpa the only genus common to both. Members are distributed mostly in the Tropics and subtropics, with the center of diversity in South America. A number of temperate species are found, mainly in North America and East Asia. 13 species in 8 genera (including 2 naturalised) are present in southern Africa. 12 genera and 35 species are present in China, 21 of which are endemic to China.
