Aubrieta deltoidea (L.) DC. (Brassicaceae) – potential ergasiophyte of the flora of Ukraine and Eastern Europe

Abstract

Objective – to provide systematic, environmental and chorological information about Aubrieta genus (Brassicaceae) and A. deltoidea (L.) DC., as well as to assess the future prospects for the distribution of plants of this species in the climatic conditions of Ukraine. Material and methods. Material from field observations of the authors, literature data and electronic resources regarding the genus Aubrieta and species A. deltoidea. The characteristic of the morphology of A. deltoidea was compiled from the results of the analysis of literature data and the study of herbarized specimens of the species used for the decoration of the “Gravel Garden” in the National Botanical Garden named after M.M. Gryshko of the NAS of Ukraine. Results. A brief history of studies of the genus Aubrieta, its position in the main classical systems of Brassicaceae and the degree of kinship with other genera of the family, including Arabis L., according to molecular biological studies, as well as floristic data regarding the genus and species are set out. The ecological and biological specificity, peculiarities of distribution and cultivation of A. deltoidea in Ukraine and Eastern Europe have been determined. Conclusion. Plants of A. deltoidea can be escape from culture and can form spontaneous populations in the climatic conditions of Ukraine. Consequently, the species is one of the potential ergaziophytes of the flora of Ukraine.
