In the paper, we analyse the distribution of species and forms closely-related to Trollius asiaticus L. growing in the mountains of South Siberia between the Altai Mountain Country and Baikalia. The interrelationship between the endemic species and forms of high-mountains and parental lowland forms are adjacent-sympatric. We suppose the ways of disruptive selection to be of the same type, thus resulting in T. sajanensis and T. altaicus speciation, which are twin-species to each other. Between the parental and daughter species, there are interlayers of morphological forms being introgressive to both species. Key words: characters, populations, disruptive selection, introgression, speciation.
