Accuracy of map:

Map is based on data from herbarium specimens and on maps of scale 1:10,000,000.

The projection:

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

Basic content:

Map is a vector file consisting of a polygon and points. Locations of species are represented by points; area of possible distribution of species is represented by a polygon.

Accuracy of qualifier:

Light-colored points represent species locations referenced in published sources. Dark-colored points represent locations of species from which herbarium samples were taken. Polygon is based on generalized information from published sources, herbarium specimens, political boundaries and ecological descriptions.

Method of map construction:

Location and area of distribution of the species is based on published maps (Grossgheim, 1967) and an analysis of herbarium materials from the Komarov Botanical Institute. Literature used includes Shishkin (1950) and Cherepanov (1995).
