Described and illustrated is Memecylon batekeanum R. D. Stone & G. M. Walters from the buffer zone of the Batéké Plateaux National Park in southeastern Gabon. This new species is closely related to M. amshoffiae Jacques-Félix of Cameroon, but is distinguished by its shrubby habit, quadrangular-alate young branchlets, fewer-flowered inflorescences, and calyptrate calyx. A provisional IUCN status of Vulnerable is assigned. Memecylon amshoffiae was treated earlier in section Mouririoidea Jacques-Félix, but this is contraindicated by evidence from ovary and anther morphology and by recent molecular phylogenetic analyses. Together, M. amshoffiae and M. batekeanum are provisionally placed next to M. diluviorum Exell in section Polyanthema Engler.
