The article contains an overview of cultivated species and hybrids and also morphological and phenological comparisons of black and balsam poplars (sect. Aigeros and sect. Tacamahaca) that occur in three cities of European Russia: Moscow, Izhevsk, and Tula. The survey has revealed a very low number of pure species. Probable parentage is proposed for a number of hybrid poplars widely deployed by the urban green industry. Consequences of poplar hybridization in natural habitats and urban settings are discussed. New nothospecies, Populus ×nevensis Nasim. is described.
