Scale:

1:20 000 000.

Accuracy of the map:

The map is based on data of 1:20 000 000, 1:25 000 000 scale maps, corrected according to herbarium materials.

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. Localities of the species are represented by dots, the area of species distribution is represented by the polygons.

Accuracy of the qualifier:

Dark dots represent information on the species localities from herbarium collections of LE, the rest (light) dots represent data from published sources.

Method of the map construction:

The species range in the former USSR consists of 5 polygons: European, European-Caucasian, Lower Volga and two Central Asian ones, and separate dots besides. The European polygon embraces a set of the species localities in the western part of the former USSR; it is mainly drawn according to materials of LE Herbarium. The European-Caucasian polygon embraces the species localities in the southern Russia, at the northeastern coasts of the Black and Azov Seas, in the Caucasus, and at the western coast of the Caspian Sea. The northern and eastern borders of the polygon are drawn according to materials of LE Herbarium and data by Hulten, Fries (1986), the southern and western ones after a published map of the species range (Grossheim, 1952). The Central Asian polygons include the species localities in the northeastern and northwestern Kopet-Dagh mountains and are drawn according to factual data of LE Herbarium and published data (Pavlov, 1961; Shishkin, Nikitin, 1950). The Lower Volga polygon includes the species localities mapped in Hulten, Fries (1986) and cited in "Flora URSS" (Shishkin, 1945 - the species localities cited in the text). Dots outside the polygon outlines represent single localities of the species beyond the borders of the final polygons.
