Abstract: This study focuses on the anatomical adaptation strategies of some spontenous perennial Amarantaceae spices in Algerian south east. Despite the morphological adaptation mechanisms aimed mainly at preserving as much water as possible, either by the succulence, or by reducing the size of organs, these Saharan plants present other mechanisms even more complex. Indeed, this study show that tissue structure offers even more opportunities to adapt to the Saharan plants: first, by the presence of cuticle or the existence of a multilayered epidermis and Hypoderm that causes the depression of the stomata; second, by varying the structure of the parenchyma, which determines the type of photosynthetic pathway. So the stem anatomy shows that the species studied have various coping mechanisms Anatomy, among others, the vary in parenchymal structure that determines the type of photosynthetic pathway, with the presence of C3 species (composed of a layer of cells all lying) and that of C4 (organized in two different seats elongated cell and cubic cell).
