The article presents some information about the new locality of the South Asian-Australian species
Hydrocharis dubia (Blume) Backer (Hydrocharitaceae) on the territory of the city of Khabarovsk
(Khabarovsky Region). According to regional reports, on the territory of the Russian Far East this species is found only in the basin of Lake Khanka (South Primorye). The new locality of the species is
rather far to the North of the range border. The species is found in the urban woodland park zone in a
small stagnant strongly eutrophicated water body located in a natural depression of the relief. The study
reveals that the species forms normally developed pure cenoses, completely covering the areas of the
open water of the reservoir. The surrounding vegetation is presented by small areas of the natural
broad-leaved forest preserved within the city with Quercus mongolica, Betula dahuricaand Tilia amurensis. In the near future the species naturalization in anthropogenic habitats beyond its natural range
should be expected. It is facilitated by the ability of the species to form a highly branched daughter
shoots system, which provides plants with intensive vegetative reproduction and active seizure of the
living space. The new locality of Hydrocharis dubiain the city of Khabarovsk has a point and adventive
character.
