Проведённый анализ сходства петрофильных флор территории высокогорных ландшафтов Центрального и СевероВосточного Кавказа показывает, что для неё необходимо скорректировать границы имеющейся схемы флористического районирования, т.к. коэффициенты сходства флористических списков свидетельствуют о возможности объединения ряда районов на основании малой степени отличия флор друг от друга и наличии достаточного количества видов, ареалы которых являются объединяющими.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim.

A list of obligate petrophytes was compiled based on the results of processing the authors' own field collections and taking into account information from floristic reports and determinants.

This analysis of the similarity of the petrophilic floras of the high-mountain landscapes of the Central and North-Eastern Caucasus has shown that it is necessary to correct the boundaries of the existing scheme of floristic zoning, since the similarity of coefficients of floristic lists indicates the possibility of combining a number of areas based on a small degree of difference between their floras and the presence of a significant number of species whose ranges are unifying.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Центральный и Северо-Восточный Кавказ</kwd><kwd>флора</kwd><kwd>флористические районы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Central and North-Eastern Caucasus</kwd><kwd>flora</kwd><kwd>floristic regions</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Кузнецов Н.И.
