The quantitative anatomical features of leaves of three species of the Magnolia genus were studied. Species of the genus (Magnolia kobus Sarg., Magnolia obovata Thunb., Magnolia denudata Desr.) growing on the territory of the Acad. O.V. Fomin Botanical Garden of Kyiv Taras Shevchenko National University. It was found out that at the first stages of ontomorphogenesis M. kobus is characterized by a less specialized type of mesophyll (homogeneous spongy type), in contrast to M. obovata and M. denudata, which are characterized by the dorsoventral type. The number of mesophyll cell layers in the studied species is 4–6. The least variable anatomical feature of the leaf in the studied species is their thickness (CV = 2%). Other anatomical features are characterized by average values of the variation coefficients (15–31%). Based on the correlation matrix correlation pleiades of leaf blade anatomical features of studied plants have been created by the method of «maximum correlation path». Using the results of correlation analysis, we determined groups of characters that exhibit an interconnected manifestation in ontogenesis due to genetic, physiological and biochemical reasons. Of the three studied species of Magnolia genus only in M. obovata, the vast majority of the studied anatomical characters are characterized by high correlation coefficients, on the first stages of ontomorphogenesis. In plants M. kobus and M. denudata, there is a stronger consistency between the traits of epidermal tissue. We assume that studied species suffer from a lack of moisture and high temperatures on the first stages of ontomorphogenesis,.
