A new species of Cercestis (Araceae), C. hepperi Jongkind from Liberia is described and illustrated. It is characterised by comparatively long pedunculate inflorescences, very dark green leaf blade with a conspicuous yellow margin and short basal lobes and by abundant stolons with persistent scaly leaves (cataphylls). Cercestis sagittatus Engler, another species from Liberia, that was synonymised with C. dinklagei Engler by Ntépé-Nyamè, is resurrected. A key to the species of Cercestis known from Liberia is provided.
