Distribution and habitat
Pachyelasma tessmannii can be found in the wet tropical regions of Cameroon, the Central African Republic, the Republic of the Congo, the Democratic Republic of the Congo, Gabon, and Nigeria.[1]
Uses
The fruit is sometimes used by fishermen in remote areas of Cameroon and the Democratic Republic of Congo for poison fishing.[5] Some cocoa farmers in Cameroon mix the bark with other plant materials and extracts to create a natural pesticide.[6]
