- Trees, shrubs or woody climbers
- Morphology Leaves
- Leaves usually alternate, simple, exstipulate

- Stamens 4–12, opposite the petals if equal in number to them, free or basally adnate to them, sometimes sterile (staminodes); anthers dithecous, with longitudinal dehiscence by means of a slit or more rarely an apical pore (not in East Africa)
- Morphology Reproductive morphology Flowers Nectaries
- Disk present
- Morphology Reproductive morphology Flowers Gynoecium
- Ovary superior, semi-inferior (caused by the expansion of the disk so enveloping the basal portion of the ovary) or inferior (as in >i>Octoknema), 1–3–5-locular; ovules 1–5, one per locule, pendulous from the apex of a central placenta; style usually short; stigma 2–5-lobed
