Scale:

1:20 000 000.

Accuracy of the map:

The map is based on data of 1:13 000 000 - 1:80 000 000 scale maps, specified according to herbarium materials.

Projection:

"Albers Equal-Area Conic Projection for USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0

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 construction:

The data from the herbarium materials of LE and WIR, published data (Grossheim, 1945, Vassilchenko, 1987), and published maps of the range (Meusel et al., 1965; Hulten, Fries, 1986) and a part of the range (Grossheim, 1952) were used for constructing the range of Medicago minima. Our view on the species distribution in Russia and adjacent states mainly agrees with the treatment of the species distribution by Meusel et al. (1965), and Hulten, Fries (1986). The range consists of four polygons and dots. The largest polygon covers the western and southern Ukraine, Crimea, Caucasus; the second large polygon is in the mountain massifs of Central Asia. The other two polygons are situated in the Caspian Lowland. Dots beyond the polygons demonstrate local species localities. The species locality in the Balkhash Lake area (after: Meusel et al., 1965) has not been confirmed by herbarium data.
