Structural features of the Orchidaceae populations
Scientific Horizons, 2020 Currently, there is an insufficient number of studies on the low-level taxonomic diversity of orchids. This situation leads to the threat of implementation of measures to protect various species at multiple levels and may lead to their extinction. This is exactly the reason for the relevance of the present study.

Classification and Phylogeny in the Orchidacea
Annals of the Missouri Botanical Garden, 1960 The nomenclature of tribes and subtribes in the Orchidaceae is reviewed, and brought into line with the rules of botanical nomenclature. Tribal definition is discussed, and a different delineation of the Neottieae and Epidendreae is proposed. The Apostasieae are considered to be primitive orchids.
