Basic contents:

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

Accuracy of the qualifier:

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

Method of the map construction:

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) and from published maps by N.N.Kachura in "Vascular plants of the Soviet Far East" (Kharkevich, 1989), V.I.Kurbatskiy in "Flora of Siberia" (Polozhij, Malyshev, 1994).
The species has a disjunctive range. The borders of the Siberian part of the range are drawn mainly according to herbarium materials referred to in the database of the Information Retrieval System; the western border after Kurbatskiy (Polozhij, Malyshev, 1994). In the Far East (continental part) and islands of Kuril chain, the range borders are drawn according to data by Kachura in (Kharkevich, 1989). The northern border of the range in Sakhalin Island is extended on the basis of herbarium collections data.
