In this article the results of the primary introduction of rare species of the genus DactylorhizaNevski in the conditions of the mountain forest zone of Eastern Kazakhstan are presents. As a result of field expedition work of 2017–2018, on the ridges of Ivanov and Kalba in the Kazakhstan section of the Altai mountain system, the following species of Dactylorhizawere added to the Altai Botanical Garden collection: D. fuchsii (Druce) Soo, D. longifolia(L. Neum.) Aver., D. incarnata(L.) Soo, D. maculata(L.) Soo, and D. umbrosa (Kar. & Kir.) Nevski. Survival rate was assessed under the conditions of introduction. The description of the external structure of generative individuals added to the culture was recorded by morphological characteristics and morphometric parameters: the shape and size of the inflorescences and leaves and the number and structure of flowers. The morphological characteristics and morphometric indicators of individuals of species added to the culture are the starting indicators when studying the introduction potential of the studied species of the genus Dactylorhiza. The collection of species of the genus Dactylorhiza will serve as the basis for the study of genetic diversity, molecular genetic analysis of species and intraspecific variability, which in turn will help to accurately distinguish between overlapping species.
