It was noted that both, native and alien fractions of the flora, are similar by high proportion of monospecific families and the Asteraceae lead. The alien fraction differs from the native one by a lower total number of families in the taxonomic spectrum, a lower rank of the Poaceae and a higher rank of the Brassicaceae. The leading families triads (the term developed by A.P. Khokhryakov for aboriginal flora of the former USSR) are not applicable for the characterization of the “railway” fl ora. The taxonomic spectrum of “railway” flora depends to a greater extent on (artificially created) edaphic factors than on climatic conditions of the territory which the railroad passes through.

In this paper some methods of analysis are suggested according to altitudinal structure of vegetation in Southern Siberian mountains and Prebaikalia at regional and topological levels. For each level climatic and orographic parameters are suggested to identify the key patterns of vegetation cover.

Approximately 30 cenotic elements, united in 10 prime ecological-cenotic groups, were identified The distribution of ecological-cenotic groups and cenotic elements within 13 botanical-geographical districts of the investigated region was analyzed. Taking into account the distribution of ecological-cenotic groups by districts, a conclusion on the predominantly forest character of the flora was made.

To study the genetic relationships between the closely related species, ISSR analysis was performed using five primers; 23 nucleotide sequences of nrITS region were obtained; 20 of them were revealed in the present study. Genetic analyses revealed a high level of variability in natural populations of P. mazurenkoae. Here we can conclude that the level of morphological similarity between P. mazurenkoae and P. farinosa correlates with the results of ISSR analysis and ITS nucleotide data obtained in the study.

A review of a very long discussion in scientific literature on the matter is provided together with the results of molecular-genetic analysis of the relevant taxa; affinities of the latter are discussed.

Their study will be of paramount importance in the long term, taking into account the creation of a general concept of ontogenesis. The general concept in its turn will contribute to the development of various branches of modern biology and ecology. That concept is utmost important in strengthening theoretical foundations of the population biology.

Khokhrjakov, a famous Soviet and Russian botanist, who was tirelessly passionate about collecting scientific herbarium throughout his life. The contribution of A.P. Khokhryakov to the study of biodiversity is shown by the example of the genus Salix L. (Salicaceae) specimens in the Digital Herbarium of the Central Siberian Botanical Garden SB RAS. Collectors of S. magadanensis Nedol. type specimens are clarified.
