It is common in southern Africa from Mozambique and Zimbabwe to South Africa. It occurs in the South African provinces of Eastern Cape, Free State, KwaZulu-Natal, Mpumalanga and Limpopo. It thrives in evergreen forests from the coast up to an altitude of 1800 meters from the Cape Peninsula to the Zimbabwe-Mozambique highlands.
Systematics
The genus Curtisia was established in 1789 by William Aiton . The botanical genus name Curtisia honors William Curtis , the founder of Botanical Magazine .
There is only one species in the genus Curtisia and therefore in the family:
- Curtisia dentata (Burm. F.) CASm. ( Syn . : Curtisia faginea Ait. , Curtisia fagifolia Salisb. )
Few authors see Curtisia faginea Ait. as a separate species.
The closest related is the Grubbiaceae family .
