Scale:

1:20 000 000.

Accuracy of the map:

The map is based on data of herbarium specimens and on 1:20 00 000-1:86 000 000 scale maps.

Projection:

"Albers Equal-Area Conic Projection for USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0

Basic contents:

The map is a vector file consisting of polygons and dots. The localities of the species are represented by dots, the area of possible species distribution is represented by polygons.

Accuracy of the qualifier:

The dots represent the species localities according to published sources and herbarium materials. The polygons are based on generalized information from published sources and herbarium materials.

Method of the map contruction:

The data on the species distribution were obtained from the database of the species localities coordinates included in the Information Retrieval System "Crop Wild Relatives in Russia" (STC Informregistr 0229905883, 1999), and from published maps by Zhukovsky (1928), Eig (1929), Slageren (1994).
The species has a disjunctive distribution. The range borders in the Crimea and the Caucasus are drawn mainly according to herbarium materials referred to in the database of the Information Retrieval System, the data by Slageren (1994) are also taken into account. The range borders in Daghestan and Turkmenia are drawn according to Slageren (1994). The isolated locality in Ciscaucasia is not included in the general polygon.
