Accuracy of the map:

The map is based on data of 1:20 000 000 - 1:25 000 000 scale maps.

Projection:

Basic contents:

The map is a vector file consisting of a polygon and dots. The localities of the species are represented by dots, the area of possible species distribution is represented by the polygon.

Accuracy of the qualifier:

The dots represent information on the species localities according to published sources and from herbarium specimens. The polygon is based on generalized information from published sources and herbarium specimens.

Method of the map contruction:

The data on the species distribution were obtained from the database of the species localities coordinates included in the Information Retrieval System "Crop Wild Relatives in Russia" (STC Informregistr 0229905883, 1999), from the map published by V.V.Busik in "Flora of the Central Siberia" (1979), N.V.Friesen (1988).
The species has a disjunctive range. The range borders in Yakutia are drawn after Friesen (1988) and extended northeasterly according to herbarium materials referred to in the database of the Information Retrieval System. The range border in Buryatia is drawn after Busik (1979), in the Chita Region after Friesen (1988). Solitary localities of the species, isolated from its main range, namely the westernmost one cited in "Manual of Plants of the Tuva Autonomous Soviet Socialist Republic" (1984), and the northernmost one validated by a nerbarium specimen, are not included in the polygons.
