Scale:

1:20,000,000.

Accuracy of map:

Map was created using maps of scale 1:11,250,000.

Projection:

"Alber.s Equal-Area Conic for the USSR", 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 (Grossgeim, 1939). The species is found in meadows, on stony slopes and among pebbles in the middle and high mountain belts of Major and Minor Caucasian ranges. 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.
