| Abstract: | In the present paper, the anatomical strcture of leaves of Alhagi pseudalhagi Desv, Halimod- endron holodendron (Pall) Voss. and Populus diversifolia Schrenk, and assimilating branches of Dodartia orientalis L. and Calligonum mongolicum Turcz. has been studied. Their anatomical structure has destinet xeromorphic characters. The cell walls of epidermis have thickened and cov- ered with thickness cuticle. Assimilating tissues all develop to palisade layvers, in which contaning abundant chloroplasts. They possess a large number of mucilage cells in parenchyma, well devel- oped water storage tissue and mechanical tissue. |
