Date of creation:

15.03.2005.

Scale:

1:20,000,000.

Accuracy of map:

Map was created using herbarium specimens and maps of scale 1:10,000,000-25,000,000.

The projection:

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

Basic content:

Map is a vector file consisting of a polygon and points. Locations of the species are represented by points, while the area of possible distribution of the species is represented by a polygon.

Accuracy of qualifier:

Light-colored points represent species locations referenced in published sources. Dark-colored points represent locations from which herbarium samples were taken. Polygon is based on generalized information from published sources, herbarium specimens, political boundaries and ecological descriptions.

Method of map construction:

The species distribution map was created using herbarium data (VIR, Komarov Botanical Institute, Botanical Institute of Armenia) and published maps of species distribution (Grossheim, 1952). Sites of species occurrence connect in Southern Transcaucasia. The main part of the distribution area lies in Iran and Armenia; therefore, the southwestern section of the distribution area lies within the former USSR. Points located outside this general distribution area represent single sites of species occurrence.
