Date of creation:

Scale:

1:20 000 000.

Accuracy of the map:

The map is based on data of herbarium specimens and on 1:11 100 000-1:80 000 000 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 species distribution is represented by polygons.

Accuracy of the qualifier:

The dots represent information on the species localities according to published sources and herbarium specimens. The polygons are 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 the maps published by Grossheim (1962), Baranova (2000), Martynenko in "Flora of the Northeast of European part of the USSR"(1976), Hulten & Fries (1986).
The northern border of the European part of the range is drawn after Hulten & Fries (1986), the northeastern one after Martynenko (1976), the eastern after Baranova (2000), the southern according to herbarium materials referred to in the database of the Information Retrieval System. Borders of Crimean part of the range are drawn according to herbarium materials, Caucasian ones after Grossheim (1962) and corrected according to herbarium materials. Several dots in the northeastern European Russia east of the Severnaya Dvina River are not included in the polygon, since Schmidt in "Flora of the Arkhangelsk Region" (2005) writes that, despite citations in "Flora of the Northeast of European part of the USSR", the species has not been found east of the Severnaya Dvina. A number of dots in the southeastern European Russia is not included in the summarized range, since the species is not cited in recent floristic treatments for these areas.
