Abstract:Hybrids between different plant species are usually ignored during studying and analysis of the regional flora. However, their presence in the floristic checklist is significant for objective description of the history of flora generation. This applies particularly to the Tyumen region. The climate and landscape of the region are conducive to appearance and spread of hybrids even in macrotaxa with relatively rare hybridization. E.g. a rare hybrid of two fern species Dryopteris × uliginosa (A. Br. ex Döll) Kuntze ex Druce was discovered in the Tyumen region for the first time in the Nizhnetavdinsky district. This is the fifth record of this hybrid in the Urals and Trans-Urals. Earlier it was found in the Kurgan, Sverdlovsk and Chelyabinsk regions. All known records of this hybrid have been made on the left bank of the Tobol River basin. This plant is an interbreeding between two most common wood fern species in the region (D. carthusiana × D. cristata). It is diagnosed by a combination of morphological features, which are typical for the parental species, as well as abortive spores. The reported data can be used by scientists and environmental protection specialists.
