Afrocarpus is a genus of conifers belonging to the Podocarp family, Podocarpaceae. Afrocarpus was designated a genus in 1989, when several species formerly classified in Podocarpus and Nageia were reclassified. Six species are recognized.
As the name intimates, Afrocarpus is native to Africa. The species are distributed through the montane forests of eastern and southern Africa, descending to the Indian Ocean coast in South Africa. A. gaussenii is native of Madagascar.
The podocarps are associated with the ancient supercontinent of Gondwana, where they were characteristic of the cool, moist southern Gondwana flora. Gondwana broke up into the continents of South America, Africa, India, Australia and Antarctica between 160 and 30 million years ago. As Africa drifted north it became hotter and drier, and the podocarps generally retreated to the cool moist highlands of eastern and southern Africa.
- A. dawei is native to the highlands of east Africa, including Kenya, Tanzania, Uganda, and Congo.
- A. falcatus, commonly known as the Outeniqua yellowwood, is a tall tree, generally 10-25 m high, but growing up to 60 m. It is native to montane forests of South Africa, from Swellendam District of Western Cape Province to Limpopo Province, and into southern Mozambique.
- A. gaussenii, native to the eastern plateau of Madagascar.
- A. gracilior, native to Ethiopia, Kenya, Tanzania, and Uganda. Used in gardens as a tree, hedge, screen, or espalier; generally sold as Podocarpus gracilior.
- A. mannii, native to the island of São Tomé in the Gulf of Guinea.
- A. usambarensis, native to Burundi, Rwanda, Congo, and Lushoto and Mbulu districts of Tanzania.
