- Family Aphloiaceae
- Family Crossosomataceae
- Family Geissolomataceae

Families
Aphloiaceae
Aphloiaceae Takht. 1985, is a monogeneric family of flowering plants. It contains only one species Aphloia theiformis (Vahl) Benn., a species of evergreen shrubs or small trees occurring in East Africa, Madagascar, the Mascarene Islands and the Seychelles. [more]
Crossosomataceae
Crossosomataceae is a small plant family, consisting of three genera of shrubs found only in the dry parts of the American southwest and Mexico. [more]
Geissolomataceae
Ixerbaceae
Stachyuraceae
Stachyuraceae is a flowering plant family of shrubs and small trees native to East and Southeast Asia. The plants have leaves with serrate margins and flowers in long, hanging racemes. [more]
Staphyleaceae
Staphyleaceae is a small family of five genera of flowering plants in the order Crossosomatales, native to the Northern Hemisphere and also in South America. The genus Staphylea, which gives the family its name, contains the "bladdernut" trees. [more]
