Annona is a genus of approximately 166 species of flowering plants in the pawpaw/sugar apple family, Annonaceae.

Annona senegalensis, commonly known as African Custard-apple, is native to Western and Southern Africa, ranging from Senegal to South Africa. A traditional food plant in Africa, its little-known fruits have the potential to improve nutrition, boost food security, foster rural development and support sustainable landcare. Annona senegalensis is a shrub or small tree 2 to 6m tall but may reach 11m under favourable conditions. The genus name, ‘Annona’, is from the Latin word ‘anon’, meaning ‘yearly produce’, referring to the production habits of fruits of the various species in this genus. The specific name means ‘of Senegal’, which is where the type specimen was collected.
