In Transbaikalia (East and West) there are 35 species of onions — Allium, family Alliaceae. As early vitamin vegetable by the local population uses the 3 closely related species of on- ion belonging to the subgenus Rhizirideum, Schoenoprasum section: A. maximowiczii, A. schoenoprasum, A. udinicum. These species are similar in morphological features, but their anatomical structure remains virtually unexplored, so the aim of this work was a compara- tive study of the anatomical features of the stem and leaf 3 of these species collected in Transbaikalia. As a result, it was found that all three species are hydrophytes and helio- phytes. Comparative anatomical analysis of the three studied species revealed the main dif- ferences in the structure of the stem and leaf of each species. Main specific sign can serve as a number of large conducting bundles in the Central cylinder of the stems: 7 bundles in A. maximowiczii, 9 bundles in A. schoenoprasum, 6 bundles in A. udinicum that noticeable their cross sections. In the structure of the leaf of the first two types of noticeable differences is not established. Endemic species A. udinicum different from the other two species of tri- hedral (rarely tetrahedral) leaves with a cavity inside.
