New collections of Geophila ingens are used for a detailed documentation, description, and discussion of the ecology and affinities of this poorly known African species. It is mainly characterised by its variable leaves, the stamen insertion below the internal indumentum of the corolla tube and the straight pyrenes. The ovate leaf blades with frequently rounded bases and the sometimes slightly woody base of the stems indicate that G. ingens may be a primitive representative of the genus. G. ingens occurs and reproduces in closed canopy forests. It has a macrodisjunct distribution (Cameroon, Congo‐Kinshasa and Uganda), corroborating existing hypotheses on the location of glacial forest refuges.
