Scale:

1:20,000,000.

Accuracy of map:

Created based on information taken from open-published literature and maps of natural scale 1:13,000,000 - 1: 80,000,000.

Projection:

"Alber's Equal Area Conic for the USSR" 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic contents:

Vector map. Area of distribution is shown by polygons (main distribution). Zone of weediness is shown by polygons.

Accuracy of classifier:

Distribution of the species is divided into zones of main distribution, moderate weediness, and sporadic distribution areas.

Method of map production:

Area and zone of weediness outlined according to results of the analysis of cartographic materials published in open literature. The map from Hulten & Fries (1986) demonstrating the presumable area was used as a basis; it was corrected according to literature data. The border of main distribution in the European part of the former USSR was specified according to Hulten & Fries (1986), supported by other references (Bakin et al., 2000; Grigor.evskaya , 2000; Ul.yanova, 1981, 1998; Maevskii. 1954; Nikitin, 1983; Rzhavitin, 1968). The southern border of distribution in Ciscaucasia was specified according to Galushko A.I. (1978) and coordinated with the limits of arable lands. The species distribution in Lower Volga Basin Region was also coordinated with the limits of arable lands. Its distribution from the Urals to Transbaikalia is supported by Volkov, 1935; Vasil.eva and Matsenko, 1964; Krasnoborov, 1979; Popov, 1957; Malyshev, 1993). The zone of weediness was outlined according to Nikitin V.V. (1983), and corrected according to data on abundance, occurrence and harmfulness of the weed; these data were taken from below-mentioned references (except Keys and Floras) and were coordinated with the limits of grain-growing lands which suffer most of all from the weed. Patches of sporadic distribution were based on literature data (Hulten & Fries, 1986; Volkov, 1935).
