Data of creation:

15.06.2004.

Scale:

1:20,000,000.

Exactness of map:

The map was created using maps of scale 1:50,000,000, 1:30,000,000, 1:10,000,000, and 1:5,000,000.

Projection:

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

Basic content:

Vector map. Locations of the species are represented by points, while the area of possible distribution of the species is represented by a polygon.

Exactness of classifier:

Points of different colors represent species locations referenced in published literature and locations from which herbarium specimens were taken.

Method of map construction:

Point area includes species locations cited in Malyshev & Peshkova (1979), Harkevich (1991), Tolmachev (1964, 1974) and Hulten & Fries (1986), as well as original locations of the specimens at the V.L. Komarov Botanical Institute herbarium. The polygon was created using species distribution data from Malyshev & Peshkova (1990), Tzvelev (1976), and Hulten & Fries (1986). The final map legend is bi-colored. Dark points represent locations from which herbarium specimens were taken. Light points represent species locations referenced in published literature. The western border of the distribution area was mapped using point data from Malyshev & Peshkova (1979), Harkevich (1991), Tolmachev (1964, 1974), Hulten & Fries (1986), and the V.L. Komarov Botanical Institute herbarium. The eastern border was mapped using point data from Hulten & Fries (1986) and the state border of Russia. The southern border was mapped using point data from Malyshev & Peshkova (1979), Harkevich (1991), and the state border of Russia. The northern border matches the coastline. Several points were not included in the polygon, as more information is needed regarding distribution of the species in these places. The species distribution map takes into account the ecological preferences of the species.
