Two natural constraints drought and salinity have altered the ecosystem stability, but it has always conditions more or less favorable to the existence of a spontaneous flora adapted to the climatic and edaphic stress. The aim of this study is to describe a halophyte native tree and its climatic and edaphic requirements, it is a case of Limoniastrum guyonianum. According to this survey L. guyonianum, grows well under high temperature, insolation and evaporation and low rainfall and humidity. The species tolerate the soil basic pH, salinity, calcareous and do not need the organic matter and chlorure ions There are some morphological adaptations in the L. guyonianium to the several conditions as the length of the root and cylindrical shapes of the leaves and their extraction of salt.展开更多
