The species most characteristic of the subregion III and of the more xerophytic zones of the subregion III (IV) is 'Argania spinosa' (Schmid). It is difficult to separate the two suborders of vegetation 'Argania' and 'Tetraclinis' which are very similar. For this reason we refer to both of them in a mixed form, as if there existed the suborder 'Argania-Tetraclinis'. The species characteristic of the suborder are Argania spinosa, Tetra- 26 clinis articulata, Periploca laevigata, Gimnosporia senegalensis, Forsskalea tenacissima, Caralluma europaea, Zizyphys lotus, etc.

Now, as it was said, this afforestation is being undertaken to meet urgent needs; and it is also necessary that the young plantations have a very good initial growth so that they are in a position to defend themselves rapidly against grazing. That is why the search for quick-growing forest species is pursued with a view to producing useful products within as short a space of time as possible and less importance is given to the perenniality of the plantation. This is justified on an economic and social basis.
