The article presents the results of a long-term of study of biological features of 54 sorts of Clematis L. genus of collection of the SouthUral Botanical Garden-Institute of UFRC RAS. The aim of the work was to summarize the introduction studies for the possibility of successful use of clematis sorts in vertical gardening in the Bashkir Cis-Urals and adjacent territories.

The aim of the research was to establish features in macrosporogenesis, macrogametogenesis, and embryogenesis in Picea species (native species P. abies and introduced species P. canadensis and P. pungens) in the Botanical Garden of Petrozavodsk State University (middle taiga subzone). To study the development of the generative sphere, shoots with generative buds and strobiles from the southwestern side of the crown were cut from 10 trees and fixed in a mixture of alcohol and glycerin.

Data on the study of morphometric parameters of medicinal plants such as Hyssopus offi cinalis L. and Nepeta pannonica L., which are part of the collection of medicinal plants of the Botanical Garden of the Orеnburg State University, are presented. It was found that the studied species successfully adapt to new growing conditions, since the parameters of morphometry vary within the medium to very high levels of variability. However, Nepeta pannonica L.
