The results of a comparative study of the structure of some vegetative organs of </span><i><span style="font-family:Verdana;">A</span></i><span style="font-family:Verdana;">.</span><i> <span style="font-family:Verdana;">caspium</span></i><span style="font-family:Verdana;"> and </span><i><span style="font-family:Verdana;">A</span></i><span style="font-family:Verdana;">.</span><i> <span style="font-family:Verdana;">tschimganicum</span></i><span style="font-family:Verdana;"> growing in natural conditions in Uzbekistan are presented for the first time. During the study of the desert representative </span><i><span style="font-family:Verdana;">A</span></i><span style="font-family:Verdana;">.</span><i> <span style="font-family:Verdana;">caspium</span></i><span style="font-family:Verdana;">, 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</span><span><span style="font-family:Verdana;">;deep submergence of stomata: extensive core: </span><span style="font-family:Verdana;">thinness</span><span style="font-family:Verdana;"> of the crustal parenchyma, the presence of lactic acid in it;the presence of a highly </span><span style="font-family:Verdana;">sclerified</span> <span style="font-family:Verdana;">sclerinchymal</span><span style="font-family:Verdana;"> ring between the crustal parenchyma and the central cylinder: the vastness of the core and the presence of </span><span style="font-family:Verdana;">hydrocytic</span><span style="font-family:Verdana;"> cells in it, as well as the similarity of the structure of </span></span><span style="font-family:Verdana;">the stem and pedicel.
