Data of creation:

28.06.2004.

Scale:

1:20,000,000.

Exactness of map:

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

Projection:

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

Basic content:

Map is vectorial. Locations of the species are represented by points, while the area of possible distribution of the species is represented by polygons.

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 from Harkevich (1991) and locations from which herbarium specimens at the V.L. Komarov Botanical Institute were taken. Polygons were constructed using species distribution data from Malyshev & Peshkova (1990) and Tzvelev (1976). The final map legend is bi-colored. Dark-colored points represent locations from which herbarium samples were taken. Light-colored points represent species locations referenced in published literature. The western border of the species distribution area was mapped using Harkevich (1991) and Malyshev & Peshkova (1990). The eastern border was mapped using Harkevich (1991) and Tzvelev (1976). The southern was mapped using Tzvelev (1976) and the state border of Russia. The northern border was mapped using Harkevich (1991) and the original locations of specimens from the V.L. Komarov Botanical Institute herbarium. Several points were not included in the polygons, as they may represent instances of species invasion. The distribution area map takes into account the ecological preferences of the species.
