Introduction. The article is devoted to current issues of lexicographic research in the field of the botanical nomenclature. A model of an integrated dendronymic dictionary is highlighted, methodology for its compilation is determined, and its role in unifying the names of green spaces of parks and squares is described. The methodological foundations for the compilation of this type of dictionary are considered, the source database of entry words is determined. The structure of the dictionary article is given. The purpose of the article is to suggest a model of an integrated dendronymic dictionary, determine the methodology of its compilation and single out its role in the unification of the green space names of parks and squares. Methodological basis. There are fundamental principles on which methodological foundations for compiling dictionaries are based. V. Dubichinsky identified five basic principles of lexicography: 1) the continuity of lexicographic works; 2) a significant role of the subjective factor in compiling dictionaries; 3) conditionality by strict pragmatism; 4) normativity in the choice of vocabulary; 5) theoretical and practical versatility of lexicographic works. The results. Dendron, a target term, should be in normative and dialect base, lexical atlas materials, scientific publications, card-indexes of recorded dendronymic dialects of the Ukrainian language and so on. The classification of the lexical-semantic categories of dendronymics used in dictionaries should correspond to the scientific traditions of botany as a science. As for the classification of any green spaces there is a procedure for description: domain, regnum, division, class, order, family, genus, species. Conclusion. An integrated dendronymic dictionary is a source where the most important information about a specific name is collected and briefly described. Upgraded informativity of dictionary entries will help realize the pragmatic goal of the dictionary – the unification of green space names on the basis of multinational identity and broad satisfaction of needs of language practice –and bring lexicographic work closer to readers. In addition, the compiled dictionary will contribute to the further unification of the Ukrainian-language botanical nomenclature (dedronym), which will concern concepts and a system of concepts, the definition for the semantic boundaries of the nomenclature, its external and internal forms, as well as graphic design methods. This research is the first attempt to generalize the experience in compiling a dictionary of botanical nomenclature (in particular, the dendronim), to emphasize the author’s vision of structuring and content of the dictionary
