Ceratonia siliqua-dominated formations, often with Olea europae var. sylvestris and Pistacia lentiscus. The most developed examples, some truly forestlike, are to be found in Tunisia, on the slopes of the Djebel Ichkeul, where they constitute carob-dominated facies of the previous unit, in Mallorca (Cneoro tricocci-Ceratonietum siliquae), in eastern Sardinia, in southeastern Sicily, in Puglia, in Crete, in northeastern Algeria, in Cyrenaica.
