Basic contents:

The map is a vector file consisting of 1 basic and 2 subject layers. The species range is represented by polygons and dots.

Accuracy of the qualifier:

The dots represent information on the species localities: 1 - reliable data from herbarium and published sources; the polygons (1) - generalized information on the species distribution from published sources and herbarium specimens.

Method of the map contruction:

The data from the herbarium materials of LE, published map of the range part (Polozhij, Malyshev, 1994), and published data (Lesins, Lesins, 1979; Small, 2003; Roskov et al, 2005) were used for constructing the range of Medicago ruthenica. The range in disjunctive and consists of two polygons and dots. The first polygon lies in the southern East Siberia, the second one in the southern Far East.
