Complexes of stem anatomical characteristics which can be applied for species diagnostic are described. Anatomy of T. arvense, T. medium and T. montanum shows xerophytic features aimed on desiccation resistance, manifested in three directions: increased functions of epidermal tissue, enhanced development of mechanical tissues, increased development of water conducting system.
