Abstract

Aquatic flora of Dagestan, the diverse region connecting the Caucasian and Aralo-Caspian floristic provinces, received little research effort. Therefore, we conducted two expeditions across aquatic and wetland habitats of Dagestan in June and September 2021 and analyzed public records of aquatic plants from the GBIF database. We report new data on distribution of 35 aquatic vascular plants taxa in Dagestan. A hybrid between Ranunculus peltatus and R. trichophyllus was firstly reported in Russia, although no occurrences of R. peltatus are known in the country. Najas major and hybrid Potamogeton × salicifolius (P. lucens × P. perfoliatus) are new to the Caucasus, and five more species are new to Dagestan (Myriophyllum sibiricum, Najas graminea, Potamogeton pusillus, Typha domingensis, Utricularia minor).
