Basic contents:

Vector map. Area of species distribution is shown by polygons, while actual location occurrence is shown by points.

Accuracy of classifier:

Point data were obtained from published sources and herbarium specimens. Polygons are based on published sources, herbarium samples, and field surveys by the authors.

Method of map production:

Published literature was reviewed, including atlases, monographs and papers. Occurrence data were obtained from herbarium specimens, floras, monographs and papers. The V.L. Komarov Institute herbarium, Grossheim (1939), and Hulten & Fries (1986) were used to map the distribution area. Data were then compiled through scanning and geo-referencing to develop a composite vector map. The biologist, together with the GIS-specialist, drew a new plant distribution area based on compiled data. Within the European part of the former USSR, the species is distributed throughout the zone of coniferous broadleaf woods and the forest-steppe zone down to the Urals. Separate locations were marked in the Crimea and the Donetsk range. In the Caucasus, the species grows in the woods of mid-elevation mountains. Taxonomic status of the species is difficult to diagnosis due to the differences in the distribution area proposed here and the area proposed by Hulten & Fries (1986).
