Neolamarckia is a genus with one or two species of trees native to the Old World tropics.

[2][1] It has often been confused with other genera, particularly Nauclea and Neonauclea to such an extent that descriptions of Neolamarckia may state incorrectly that its fruit is a capsule.

[1] The inflorescenes are spherical, containing many small flowers.

[1] The genus name was created to replace Anthocephalus, which had been based on two unrelated herbarium specimens, one of which was mislabelled.

Consequently, the true Anthocephalus is a synonym of the genus Breonia, and a new name was needed for the trees that had been generally known by the incorrect name.
