Irvingia gabonensis is a species of African trees in the genus Irvingia, sometimes known by the common names wild mango, African mango, bush mango or dika. They bear edible mango-like fruits, and are especially valued for their fat- and protein-rich nuts.
The tree is present in the tropical wet and dry climate zone. Dika grows naturally in canopied jungle, gallery forests and semi-deciduous forests. It grows at altitudes from 200–500 m with annual rainfalls from 1200–1500 mm. Supported temperature ranges from 20° to 38 °C under slightly shaded to very bright, clear skies. Deep soils with more than 150 centimetres (59 in) are needed with a moderate fertility and good drainage. pH can range from 4.5 to 7.5.
Irvingia gabonensis grows straight, up to a height of 40 metres (130 ft) and 1 metre (3 ft 3 in) in diameter. It has buttresses to a height of 3 metres (9.8 ft). The outer bark is smooth to scaly with grey to yellow-grey color. The crown is evergreen, spherical and dense. Leaves are elliptic, one margin is often a little rounder than the other, acuminate, dark green and glossy on the upside. Flowers are yellow to greenish-white in small panicles. The flowers are bisexual. The fruit is nearly spherical, green when ripe with a bright orange pulp. The stone is woody and contains one seed. Seedling germinates epigeally.
