Scale:

1:20,000,000.

Exactness of map:

The map was created using maps of scale 1:25,000,000-1:40,000,000.

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 a polygon. Locations of species are represented by points; area of possible distribution of species is represented by the polygon.

Exactness of classifier:

Light-colored points represent locations referenced in published sources. Dark-colored points represent locations of the species reported in the databases of the N.I. Vavilov All-Russian Research Institute of Plant Industry and the V.L. Komarov Botanical Institute. Polygon is based on published sources, herbarium samples, political boundaries and ecological descriptions.

Method of map construction:

The maps of species distribution areas published by Harkevich (1985) and Malyshev & Peshkova (1990) and herbarium data (V.L. Komarov Botanical Institute, N.I. Vavilov All Russian Institute of Plant Industry) were used to construct the distribution area. The presented distribution area created by generalizing such data is represented by the polygon (green line). The distribution area border is based on all available data, wherein there are no significant contradictions. The polygon covers the arctic area of Russian Europe, the Urals, Siberia and the Far East. The distribution area borders take into account the ecological preferences of the species.
