Anatomical structure of the stem and leaf of and (Rosaceae)

Using light microscopy, a comparative study of the signs of the anatomical structure of the stem and leaf of 2 morphologically similar species of the genus L.: (Maxim.) Takeda and Fisch. ex Link was carried out. In the stem structure of the studied species, the diagnostic feature is only the number of conducting beams on the cross section. We have not identified any taxonomically significant features in the structure of the leaf. We agree with the opinion of those taxonomists who consider as a synonym of . Conventionally, only quantitative signs can be informative: the thickness of the leaf blade, the length of the cells of the upper epidermis, the number of stomata per 1 mm of the leaf surface.
