Commonly known as the "snuff-box tree," it comprises around 100 species found primarily in tropical regions of Africa, with a few species also found in Madagascar and the Indian Ocean islands. The name "dichapetalum" is derived from the Greek words "di" meaning two and "chape" meaning hood, referring to the unique shape of the fruits, which resemble a hinged snuffbox when split open.

They typically have simple, opposite leaves with entire or toothed margins. The flowers of Dichapetalum are usually small and inconspicuous, arranged in clusters or panicles. The fruits are distinctive, consisting of a pair of woody, horn-like capsules that split open to release seeds when mature. They often possess bright red or black seeds that are poisonous if ingested.
In various African cultures, some species of Dichapetalum are utilized for medicinal purposes. Extracts from certain plants in the genus have been used as arrow poisons, with their toxic properties attributed to the presence of diterpene esters. The seeds of Dichapetalum species are also known for their toxic effects on livestock, causing muscle weakness, paralysis, and even death in severe cases.
Overall, the genus Dichapetalum represents an intriguing group of plants known for their unique fruits and various medicinal and toxic properties.
