Scale:

1:20 000 000.

Accuracy of the map:

The map is based on data of a 1:40 000 000 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 a polygon and dots.

Accuracy of the qualifier:

The dots represent information on the species localities: reliable data according to herbarium (1) and published sources (2); the polygons - generalized information on the species distribution from published and herbarium materials.

Method of the map construction:

The range of Eurotia ceratoides is constructed using factual data of herbarium materials of LE, and on the base of a published map of the species range (Sokolov et al., 1980). The final range consists of a polygon and separate dots. The main polygon embraces the southeastern European Russia, Caucasus, Central Asia and Kazakhstan (except for desert zone, where the species occurs only in river valleys), as well as the southern West and Central Siberia. A number of ecotypes is distinguished within the species, occurring in different habitats. The species is also recorded in the Crimea and southern Ukraine, where it mainly occurs on chalky cliffs of riversides. Dots beyond the borders of the polygon represent the species localities outside the main range.
