1:20 000 000.Accuracy of map:
It is created on information taken from the open-published literature and on 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 polygon (main distribution). Zone of weediness is shown by polygon.Accuracy of the classifier:
Distribution of the species is divided into zones of the main distribution, moderate weediness, and sporadic distribution areas.Procedure of map drawing:
The map is compiled by results of the analysis of the open published cartographic materials and literature. A map from Hulten & Fries (1986) containing presumable area is used as a basis for a map of L. remotum; it is corrected according to herbarium and literature data. The border of the main distribution in Russia and adjacent countries has been specified after literature data (Gubanov et al., 2000; Maevskii, 1954; Keller, 1934; Krasnoborov, 1979; Nikitin, 1983; Prokudin, 1987; SHishkin, 1963) and maps of the species distribution in floristic regions (Komarov, 1934; Fedorov, 1974). The zone of weediness is outlined after Nikitin V.V. (1983), being corrected according to data on abundance, occurrence and harmfulness of the weed; these data have been taken from below mentioned references and have been coordinated with the limits of flax-growing lands because they suffer from the weed most of all. Patches of sporadic distribution are taken from cartographic (Hulten E., Fries M., 1986; Volkov, 1935), literature (Bakin, 2000; Tolmachev, 1966; Kharkevich, 1985), and herbarial data.Sources of the data:
