The paper presents data on the ecological and phytocoenotic conditions of habitats of the G. conopsea (L.) R. Br. orchid in the Northeast of European Russia (Komi Republic, Russia). The data include characteristics of the populations of this species on the northern border of its range (size and ontogenetic structure of the populations, density of specimens, phenology), as well as information demonstrating the genetic variability of the species by ISSR-markers that was not included in the main publication. The data presented here supplement our earlier published results O.E.Valuyskikh et al., 2019 and are useful for more detailed analysis of population biology and genetic variability of this rare orchid species. G. conopsea is the species of terrestrial orchids widespread in Europe and Asia and characterized by the widest ecological-cenotic amplitude and occurrence in different types of ecotopes. The size of G. conopsea populations in different parts of its range is usually small, 25-100 ind. but sometimes increases to 200-1000 ind. Hansen et al., 1999 to Travnichek et al., 2012. In the many regions of the Russian Federation, the G. conopsea are subject to protection due to the small number of habitats, long stages of ontogenesis, low population sizes and anthropogenic impact. The complex of G. conopsea s.l. included in the Red Data Book of the Komi Republic Taskaev, 2009.
