Accuracy of map:

Map was created using herbarium specimens and maps of scale 1:13,000,000-1:25,000,000.

The projection:

"Alber's Equal Area Conic for Russia", 9, 1001, 7, 100, 0, 44, 68, 0, 0.

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. 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. Species distribution was determined according to the following sources: the N.I. Vavilov Institute (1992), Sokolov et al. (1980) and Grossgeim (1952). The species has a disjunctive area. In the Caucasus, distribution area borders were determined using Grossgeim (1952) and Sokolov et al. (1980) and adjusted in accordance with herbarium data from the N.I. Vavilov All-Russian Institute of Plant Industry and the V.L. Komarov Botanical Institute. In the Crimea, the border was determined using Sokolov et al. (1980) and herbarium data from the above-mentioned herbariums. In Middle Asia (Western Kopetdag, namely the ravine of Gyuyen on the Chandyr River, the vicinity of Koyna-Kosyr Village, and the valley of the Sumbar River), species distribution was determined using Sokolov et al. (1980) and herbarium data from the V.L. Komarov Botanical Institute.
