Basic contents:

The map is a vector file consisting of 1 basic and 3 subject layers. The species range is represented by a polygon and dots.

Accuracy of the qualifier:

The dots represent information on the species localities according to herbarium materials of LE (1) and published sources (2), the polygon - generalized information on the species distribution.

Method of the map contruction:

The range map is based on coordinates according to herbarium materials of V.L.Komarov Botanical Institute (LE), and published maps (Kharkevich, 1985; Malyshev, Peshkova, 1990). Three areas can be distinguished within the species range: the main part of the range is represented by steppes, forest-steppes and steppified forests of the Angara River area, Transbaikal area, Dauria and the Amur River area; separate areas are situated in the forest-steppe of Khakassia Depression and the Khanka Lake plain (naturalized populations, in opinion of the monograph authors).
