2-celled, longitudinally dehiscent
. Pistil consisting of 2-5(or 10-12) ± connate carpels, or a single carpel; ovary superior, 2-5(or 10-12) -loculed; ovules 2 or more per locule; style 1 or as many as carpels.

About 68 genera and ca.
1100 species: tropics and subtropics of both hemispheres, a few in temperate regions
; 19 genera (two introduced
) and 90 species (39 endemic, three introduced) in China.
The Chinese genera fit into four distinct
clades which can be treated as subfamilies of an enlarged Malvaceae or as distinct families. These are Sterculioideae/Sterculiaceae s.s. (genera 1-4), Helicteroideae/Helicteraceae (genera 5 and 6), Byttnerioideae/Byttneriaceae (genera 7-13), and Dombeyoideae/Pentapetaceae (genera 14-19) .[1]
