- The survey of floral variability of carob tree (Ceratonia siliqua L.) from the Province of Chefchaouen (NW of Morocco) marks an unsteady floral mosaic. The determinate and the indeterminate inflorescences development is not controlled by environmental conditions in the study area. ln carob tree, the indeterminate inflorescences rate is generally higher than the determinate inflorescences one. The particular inflorescence types have been observed. Inflorescence length and flowers number per inflorescence would not related to environmental conditions. Inflorescence length is superior in male trees when compared to female ones (5.71 cm YS.4.45 cm). Flowers number per inflorescence in male trees is superior to the one in female trees (42 flowers YS.30 flowers). In male carob tree, seven flower types have been distinguished differing by sepals and stamens numbers and filament length. In female carob tree, three flower types have been defined in terms of pistil form. The grafting of male or female trees in the domesticated areas affects the sex-ratio in this species. Pollen grains diameter and potential fertility show a high variability and could not be explained by the studied factors. The diameter of pollen grains is 28.3±2.43 μm. The aborted pollen rate has been estimated to 15 %. Key words: Floral variability, pollen, Sex-ratio, Ceratonia siliqua L., NW of Morocco.
