Abstract

As a result of field research, revising the collections stored in the MW, NSK, NS, TK Herbaria, as well as in the international database Jstor, and acquaintance with protologues, the species Buglossoides glandulosa was identified on the territory of the Lower Volga region and the North Caucasus. It is shown that B. glandulosa is a priority name for B. czernjajevii, a species reliably known from of Ukraine and Moldova, and reported from a few localities in the south of the European part of Russia. The morphological and ecological-coenotic features of B. glandulosa and its differences from the closely related species B. arvensis and B. tenuiflora are discussed. The diagnostic characters of the species are given in the table and in the figure. For all species, a nomenclature citation is provided, information on type specimens, ecological features and general range, lists of studied specimens are cited. The map shows new localities of B. glandulosa in the Lower Volga region and in the North Caucasus.
