N2  -  Based on scanning electron microscopy, ultrastructure of leaf surfaces, pollen grains and seeds have been investigated for two  Atocion  Adans. species – Ukrainian endemic  A. hypanicum  (Klok.) Tzvel., and  A. compactum  (Fisch.) Tzvel., which areal comprises the Balkans, Caucasus and Western Asia. New delimiting micromorphological characteristics, associated with ultrastracture of pollen grains (microechinate number on the operculum:  A. hypanicum  – 6-15,  A. compactum  – 11-26) and interporal distance ( A. hypanicum  – 6.72±1,2 µm,  A. compactum  – 5.19±1,22 µm), have been designated . A. compactum  seeds also clearly differ from  A. hypanicum  by the papilla presence on periclinal walls of lateral and dorsal surfaces. However, ultrastructure of the leaf surface, including epicuticular wax projections, does not significantly differ between these taxa.
