The Argan tree (A rgania Sideroxylon), which forms forests in Morocco, is a remarkable survivor of a tropical family (Sapotaceae).
The chief trade is in, and the principal exports are, palm oil and kernels, rubber, cotton, maize, groundnuts (Arachis), shea-butter from the Bassia parkii (Sapotaceae), fibres of the Raphia vinifera, and the Sansevieria guineensis, indigo, and kola nuts, ebony and other valuable wood.
The chief trees belong to the orders of Terebinthaceae, Sapindaceae, Meliaceae, Clusiaceae, Dipterocarpaceae, Ternstroemiaceae, Leguminosae, laurels, oaks and figs, with Dilleniaceae, Sapotaceae and nutmegs.
The flora includes mangroves, Rubiaceae, Sapotaceae and other forms requiring more than pure coralline material for their growth.
