Data of creation:

16.06.2004.

Scale:

1:20,000,000.

Exactness of map:

The map created with 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 presented as points, while the area of possible distribution of the species is presented as a polygon.

Exactness of classifier:

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

Method of map construction:

Point area includes species locations referenced in Harkevich (1991) and original locations of the specimens at the V.L. Komarov Botanical Institute herbarium. Polygon areas were constructed using species distribution data from Malyshev & Peshkova (1990) and Tzvelev (1976). The final map legend is bi-colored. Dark points represent locations from which herbarium samples were taken. Light points represent species locations referenced in published literature. Polygon area was created by integrating maps that showed an accurate western border with point data of specimen locations from the V.L. Komarov Botanic Institute herbarium and data from Malyshev & Peshkova (1990). The northern border was constructed using point data from Harkevich (1991) and original locations of the specimens at the V.L. Komarov Botanical Institute herbarium. The eastern border was constructed using point data from Harkevich (1991) and the coast line. The southern border matches the state border of Russia. Several points were not included in the polygon, as they represent sites of species invasion. The distribution area map takes into account the ecological preferences of the species.
