Accuracy of map:

Map was created using herbarium specimens and maps of scale 1:17,000,000-1:25,000,000.

The projection:

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

Basic contents:

Map is a vector file consisting of polygons and points. Locations of the species are represented by points, while the areas of possible distribution of the species are represented by polygons.

Accuracy of qualifier:

Points represent locations of the species referenced in published sources and from which herbarium specimens were taken. Polygons are based on generalized information from published sources and herbarium specimens.

Method of map construction:

The data on species distribution were obtained from the database of species locations, the Information Retrieval System, "Wild-growing relatives of cultural plants of Russia" (NTC "Informregister" № 0229905883, 1999), and published maps in Schmidt (1990), Krasnoborov & Malyshev (1988), Malyshev & Peshkova (1979), and Kharkevich (1989). The species has a disjunctive area. The western border of the largest polygon was determined using Schmidt (1990). The northern border of this area was determined using Krasnoborov & Malyshev (1988) and information from herbarium specimens. This information is kept in the IRS database. The eastern border was extended based on information from herbarium specimens and Kharkevich (1989). The southeastern border was adjusted using Kharkevich (1989). In Primorski Krai and Kamchatka, the borders of the small polygons were determined using Kharkevich (1989). In Western Siberia, the borders of this polygon were mapped using Schmidt (1990). In Eastern Siberia and the Far East, individual locations of this species were not included in the polygons.
