The principal features of cenotic population and features of distribution of the species of Orchidaceae family in Transbaikalia region are under consideration in the paper. The species diversity of Orchidaceae family and the phytocenotic location in the reserves of Transbaikalia region are revealed. The characteristics of cenotic population are given taking the genera Cypripedium as an example. The state of six cenotic populations of Cypripedium species showed that they develop successfully that is supported by prevalence of virginal and generative individuals and as following the right-hand ontogenetic spectra. The cartographic schemes of altitudinal distribution of Orchidaceae species for the territory under consideration had been works out. Analysis of cartographic schemes of the species included in the Red Data Book on the territory of reserves in Transbaikalia showed the location of principal part of species in the valleys of big rivers with sufficient humidification.
Keywords: cenotic population, phytocenotic location, Transbaikalia, Orchidaceae family, altitudinal distribution.
