Biosystems Diversity, 27(1), 3–15. doi:10.15421/011901 Received in revised form 07.02.2019 The paper presents a chorologically systematized description of all taxa of the Drosera L. genus in Ukraine. We performed an Accepted 09.02.2019 analysis of environmental conditions, phytocoenotic characteristics and found new locations of sundew. We generalized the morphometric parameters and proposed a concept – “leaf roundness index”; and recommended including Drosera rotundifolia, Institute of Agroecology Drosera x obovata in the next edition of the Red Data Book of Ukraine due to the contraction of their habitat and their high degree and Environmental of vulnerability to unfavourable environmental factors and anthropogenic impact; we reccommend growing Drosera ex-situ on Management NAAS of Ukraine, the example of Kremenets Botanical Garden with further repatriation in-situ; proved the efficiency of the proposed methods of Metrologichna st., 12, Kyiv, 03143, Ukraine. farming cultivation. The paper substantiates the complex of phytosozological criteria, measures for protection and reproduction of Tel.: +38-044-522-60-63. the endangered species of Drosera genus. We suggested a hypothesis about the independence of the taxon of Drosera x obovata.
