THE FORESTS OF WESTERN AFRICA 19 



Forests are in addition named after the locality, such as Benin 

 Forests, Oban Forests, Ondo Forests. Again, yet another nomen- 

 clature is after the kind of tree represented, such as Evergreen Forest, 

 where all the trees are evergreen all the year round ; for instance, 

 Calabar Forests, Ondo, South Benin. 



The mixed forests and intermediate forests, where the trees are 

 both evergreen and deciduous, growing side by side, such as Olokemeji
