The Pistacia terebinthus L., is a species belonging to the family Anacardiaceae; a deciduous plant growing in the matorrals, common throughout the Mediterranean basin. The region of Tlemcen, an integral part of Mediterranean ecosystems, is characterized by several climatic and anthropic constraints that can influence the morphology of plant species. Following these constraints and recordings of some phenotypic variations in the station of Beni Snous, it seemed to us that there could be a new species or variety.The sampling adopted is of subjective type by taking into account the floristic homogeneity and the ecological homogeneity of the station.The choice of the station of Beni Snous was justified by the presence of good subjects of Pistacia terebinthus L.the most representative of the study area.In order to meet our objective, the morphometric analysis was performed on the leaves of 16 individuals, that is to say a total of 1126 leaves and 7837 leaflets measured.The statistical analysis of linear correlation, showed us the types of relationships that exist between the measured parameters.According to our results the length of the leaflets is between 3.3 cm and 4.93 cm and the width between 1.38 cm and 2.43 cm; and the number of leaflets in a leaf is on average between 5 and 11 leaflets.In conclusion, according to the analysis and the synthesis of our results of measurements on the one hand, and the comapraison with the bibliography on the other hand, we confirmed that it is the same species.
