The carob tree (Ceratonia siliqua L., Fabaceae) is a forest spontaneous and cultivated species, and grows in the Mediterranean countries and climates. It occupies a socioeconomic rank increasingly growing, both for the local population and national economies. Depending on tree characteristics and its components, authors often use geographical and/or local names especially in countries that market the carob pods. In Morocco, four intra-specific categories of carob tree were defined primarily in terms of reproductive traits and grafting, namely, “Lanta,” productive “Dkar,” unproductive “Dkar,” and “Sterile.” This work summarizes the state of knowledge on these categories and compares them with categories from other Mediterranean countries and climates, based on various descriptions and characteristics
