Date of creation:

24.12.2004.

Scale:

1:20,000,000.

Exactness of map:

Map was created using herbarium specimens and maps of scale 1:13,000,000-1:80,000,000.

The projection:

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

Basic contents:

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

Accuracy of classifier:

Points represent locations of the species referenced in published sources and from herbarium specimens. Polygons are based on generalized information from published sources and herbarium specimens.

Method of map production:

Species location data were obtained from a database of species locations, the INFORMATION RETRIEVAL SYSTEM, "Wild-growing relatives of cultural plants of Russia" (NTC "Informregistr" № 0229905883, 1999) and from maps published in Grossgeim (1952), Sokolov et al (1980) and Luneva (1985). The species has a disjunctive distribution area. In the Caucasus, the borders of the area were constructed using maps by Luneva (1985) and Sokolov et al (1980) and were corrected using information from WIR herbarium specimens. In Middle Asia, the borders of the distribution area in Kopet Dagh were drawn in accordance with Sokolov et al (1980); the borders in Tien Shan and Pamir-Alai were constructed using information from WIR herbarium specimens.
