Accuracy of map:

Map was created using data from 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; 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 following sources were used to determine the species location: N.I. Vavilov Institute (1992), Sokolov et al. (1980) and Grossgeim (1952). 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. The species has a disjunctive area. In the Caucasus, the northern border of the area was determined using herbarium data from the N.I. Vavilov Institute and the V.L. Komarov Botanical Institute. In Central Asia (Western Kopetdag), the area was determined using Sokolov et al. (1980) and adjusted in accordance with herbarium data from the N.I. Vavilov Institute and the V.L. Komarov Botanical Institute.
