Scale:

1:20 000 000.

Accuracy of the map:

The map is based on data of a 1:13 000 000 scale map, 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; 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, a published map of a part of the range (Grossheim, 1952), and published data (Grossheim, 1945, Vassilchenko, 1949, 1987; Sinskaya, 1950; Lesins, Lesins, 1979) were used for constructing the range of Medicago marina. The species occurs solely on sands at sea coasts. The range consists of two polygons, which embrace all dot localities of the species according to the data of herbarium and the map by Grossheim (1952). One polygon is situated at the western coast of Crimea, the second one in the northern part of the Black Sea coast of the Caucasus.
