Nauclea latifolia

Nauclea latifolia, also known by its common name African peach, is a species of flowering plant in the family Rubiaceae, native to tropical regions of sub-Saharan Africa.

It grows as a spreading deciduous or evergreen shrub or small tree, typically 4–6 m tall, though it may reach greater heights under favorable forest conditions. The species is characterized by a multi-stemmed habit, rough dark grey-brown bark, opposite glossy green leaves, and terminal spherical heads of small, fragrant white to yellowish flowers. It produces fleshy syncarp fruits up to 8 cm in diameter containing numerous small seeds embedded in sweet, edible pink pulp.

It is widely known in traditional African medicine as "African quinine" due to its antimalarial properties. Various parts of the plant, including roots, bark, leaves, and fruits, are used to treat fever, pain, diarrhea, diabetes, and infectious diseases, while the fruits are consumed as a famine food rich in carbohydrates, vitamins, and minerals.

Taxonomy

It was first described scientifically by the British botanist James Edward Smith in 1813. The species has historically been placed in the genus Sarcocephalus, and a widely cited synonym is Sarcocephalus latifolius (Sm.) E.A. Bruce.

The genus name Nauclea derives from the Ancient Greek naus (ship) and kleio (to close), referring to the structure of the fruit, while the species epithet latifolia originates from Latin latus (broad) and folium (leaf), describing the plant's broad leaves.

Modern phylogenetic studies support the inclusion of African species such as N. latifolia within a broadly circumscribed Nauclea to maintain monophyly of the genus.
