摘 要：The results of a comparative study of the structure of some vegetative organs of A. caspium and A. tschimganicum growing in natural conditions in Uzbekistan are presented for the first time. During the study of the desert representative A. caspium, the following diagnostic, structural features were revealed: ribbing of the peduncle and pedicel;thickening of the outer wall of the epidermis and wavy folding of the cuticle of the parenchymal-bundle type of structure;deep submergence of stomata: extensive core: thinness of the crustal parenchyma, the presence of lactic acid in it;the presence of a highly sclerified sclerinchymal ring between the crustal parenchyma and the central cylinder: the vastness of the core and the presence of hydrocytic cells in it, as well as the similarity of the structure of the stem and pedicel. In this species, a predominance of xeromorphic characters was noted, due to a tendency indicating xerophilization and adaptation to desert conditio
