Description
Dichapetalum is a genus of flowering plants in the family Dichapetalaceae. This genus comprises about 80 species of trees and shrubs that are native to tropical and subtropical regions of Africa, Madagascar, and Southeast Asia. Dichapetalum plants have small and inconspicuous flowers that grow in clusters. However, what makes Dichapetalum plants unique is their fruit, which is a drupe that contains a toxic compound called diphacinone. This toxin is used as a rodenticide, and some species of Dichapetalum are still used as a traditional poison in Africa.
