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 species distribution is represented by the polygon.

Accuracy of the qualifier:

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

Method of the map construction:

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 data on the species distribution (Yuzepchuk, 1949). The polygon borders are drawn after herbarium materials referred to in the database of the Information Retrieval System.
