Abstract: The aim: To study of the morphological and anatomical features of the structure of inflorescence of Chrysanthemum × hortorum Bailey, variety Pectoral.Materials and methods: The inflorescence of Chrysanthemum × hortorum Bailey, cultivar Pectoral were used for the analysis. The raw materials were harvested in the phase of mass flowering of plants in September-October 2019 at the experimental plots of the department of floral and ornamental plants of the National Botanical Garden named after M.M. Grishko of the National Academy of Sciences of Ukraine in Kyiv.Results: The investigated inflorescence are represented by bright orange double baskets, consisting of seated semiflorets and disk flowers arranged spirally on a convex bare anthoclinium. The involucrum of Chrysanthemum × hortorum Bailey inflorescence of the Pectoral variety has a dense structure with elongated leathery leaves. The marginal flowers of the anthodium are red-orange, pseudo-ligate female; the middle flowers are yellow, tubular, bisexual. The apex and edge of the epidermal cells of pseudo-ligate flowers are characterized by papillary growth and slight folding of the cuticle; at the base of the corolla lingula there are cells with calcium oxalate crystals in the form of small druses. The anatomical structure of tubular flowers is characterized by essential oil glands, typical for the Asteraceae family. The epidermis of the wrapper leaves is represented by oval cells with numerous essential oil glands and large surface outgrowths.Conclusions: The main diagnostic morphological and anatomical features of the inflorescence of Chrysanthemum × hortorum Bailey cultivar Pectoral have been established, which can be further used in the identification of new medicinal plant materials.
