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.

The 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 (V.L. Komarov Institute; Grossgeim, 1939). Within the former USSR, the species is found in foothills and the low mountain belts of Eastern Transcaucasia and Central Asia. 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.
