Accuracy of the map:

The map is based on data of 1:10 000 000 - 1:13 000 000.

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 a polygon and dots. The localities of the species are represented by dots, the area of possible species distribution is represented by the polygon.

Accuracy of the qualifier:

The dots represent information on the species localities according to published sources and herbarium specimens. The polygon is based on generalized information from published sources and herbarium specimens.

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), from maps published by Grossheim (1940), from published data on the species distribution by A.I.Vvedensky (Ovczinnikov, 1963) and Pavlov (1958). The species has a disjunctive range. The range borders in the Caucasus are drawn after Grossheim (1940), in the Central Asia according to herbarium materials referred to in the database of the Information Retrieval System, and corrected after published data (Vvedensky, 1935; Ovczinnikov, 1963; Pavlov, 1958).
