The article is concerned with the difficulties of species identification of the Delphinium (Ranunculaceae) herbarium specimens gathered in the Lower Volga region (Astrakhan, Volgograd and Saratov oblasts) and the adjacent regions (Penza, Samara, Tambov and Ulyanovsk oblasts and the Republic of Mordovia). The specimens from a number of herbaria (MW, LE, SARAT, SARBG, GMU, PVB) are subject to the research. It is revealed that their classification is problematic due to the absence of clear-cut classifying morphological parameters.
