Notes.

Artabotrys jacquesfelicis is distinguished by its entirely glabrous branches, petioles and leaves that are shiny above in herbarium material, narrowly ellipsoid flower buds, petals with a large concave base abruptly narrowing into an upper linear section, and ellipsoid monocarps with a warty to verrucose surface. In Cameroon, this species is only known from three old collections.
