On the distribution of Allium caeruleum and A. regelianum (Alliaceae Borkh.) in the territory of the Saratov region

Abstract

Concerning the distribution of Allium caeruleum Pall. and A. regelianum A. K. Becker, recent literary sources provide confl icting information. Based on the data from the doctoral dissertation of A. O. Tarasov, the results of expeditionary research and our own herbarium collections, it is stated that Allium caeruleum is distributed in the Ozinsky (at least in the vicinity of the village of Nepryakin) and in the Aleksandrovo-Gaisky (at least in the vicinity of the village of Kamyshki) districts of the Saratov region. The presence of A. regelianum in the Saratov region is, however, unlikely. The published key for identifying species of the genus Allium (Bulany et al., 2023) is incorrect, since it does not take into account the presence of bulblets in the infl orescence of A. caeruleum. It is proposed to make changes to the key for identifying onions, taking into account the presence of onions in the infl orescence of A. caeruleum.
