New data on aquatic flora of eastern Uzbekistan highlight the need of its detailed study in the whole country

The floristic research in Uzbekistan was intensified in the 21st century, being raised on new methodological level. As plants of aquatic habitats are often missed in routine floristic studies, we aimed to test the completeness of aquatic flora representation in the checklists, published recently for particular administrative regions. We studied all types of waterbodies in Dzhizak, Navoi, Samarkand and Tashkent regions. We revealed three taxa new for Uzbekistan (Bolbochoenus laticarpus, Potamogeton × angustifolius, Limosella aquatica). All the 12 species that we found for the first time in some regions of the country are not rare in Uzbekistan and in Central Asia in general. Thus, in spite of significant progress of floristic studies in Uzbekistan, more attention still should be paid to aquatic plants. Lowland artificial freshwater reservoirs and montane lakes are the most promising for future aquatic plant surveys.
