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; 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, published map of the range part (Grossheim, 1952), and published data (Shishkin, 1946; Fedorov, Tzvelev, 1987) were used for constructing the range of Astragalus cicer. The range consists of two polygons and dots. The larger polygon takes the central and southern areas of the European part of the former USSR, except for the dry steppe zone, and the Caucasus. The smaller polygon is situated in the mountain Crimea.
