A revision of the five Madagascan species of the genus Manilkara (Sapotaceae) is presented, including a key, descriptions, diagnostic characters, ecological notes and a distribution map. Of the seven species originally described by Aubréville, Manilkara tampoloensis is placed in synonymy with M. boivinii, and M. sohihy is removed from the genus and placed within the existing Labramia boivinii (Pierre) Aubrév.
