A study of the stem or of the leaf anatomy of Chenopodiaceae inventoried in the Northern part of Algerian Sahara showed a specific organization of the assimilating parenchyma of these species. This anatomical adaptation is correlated to a physiological one, many species being characterized by a C 4 pathway of carbon fixation.
