Psychotria elephantina Lachenaud & Cheek is described as a new species. It is placed in P. sect. Involucratae (Petit) Verdc., endemic to the South West Region of Cameroon and is assessed as ‘Endangered’ (EN) using the IUCN criteria. The species is distinctive in P. sect. Involucratae due to its long petioles (6.5–12.0 cm), involucres of two pairs of large free bracts and green corollas with included stamens in both longistylous and brevistylous flowers.
