Included here are the coastal deserts and semi-deserts of Chile and Peru including the Atacama Desert and the lowlands and semi-uplands of northern Chile. The zone extends from southern Peru to northern Chile with its southern boundary roughly coinciding with the town of Coquimbo. Deserts and semi-deserts form a continuous belt along this western escarpment of the Andean Cordillera for some 3500 km.
Of the endemic and near endemic vascular plants so far recorded there are about 152 species in 74 genera and 36 families and 2 endemic genera (marked red).
