Scale:

1:20,000,000.

Accuracy of map:

Map was created using data from herbarium specimens, published sources and maps of scale 1:13,000,000.

The projection:

"Alber's Equal Area Conic for Russia", 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic contents:

Map is a vector file consisting of polygons and points. Locations of species are represented by points; areas of possible distribution of species are represented by polygons.

Accuracy of qualifier:

Points represent locations of the species referenced in published sources and locations from which herbarium specimens were taken. Polygons are based on generalized information from published sources and herbarium specimens.

Method of map construction:

The data on distribution of the species were obtained from a database of site coordinates of the species, the Information Retrieval System, "Wild-growing relatives of cultural plants of Russia" (NTC "Informregistr" #0229905883), and the published maps of Grossgeim (1939). Within the former USSR, the species is distributed throughout Crimea and the Caucasus. The distribution area of the species consists of two regions - Crimean and Caucasian. The Crimean region includes species locations in southern, eastern and western parts of the Crimean peninsula and is limited by the coast of the Black Sea from the south, the west and the east. From the north, it is limited the dry steppe zone. The Caucasian region is located in the extreme northeast of the Caucasus and includes species locations along the northeastern part of the Black Sea coast. The points that were not used to construct these distribution areas represent individual species locations outside the general distribution area.
