Accuracy of the map:

The map is based on data of herbarium specimens and on a 1:13 100 000 scale map.

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 polygons and dots. The localities of the species are represented by dots; the area of species distribution is represented by polygons.

Accuracy of the qualifier:

The dots represent information on the species localities according to published sources and herbarium specimens. The polygons are based on generalized information from published sources and herbarium specimens.

Method of the map construction:

The data on the species distribution were obtained from the database of the species localities coordinates included in the Information Retrieval System "Crop Wild Relatives in Russia" (STC Informregistr 0229905883, 1999), and from the map published by Grossheim (1962). The borders of the Crimean and the Black Sea parts of the range are drawn according to herbarium materials referred to in the database of the Information Retrieval System. Borders of the other polygons are drawn according to herbarium materials with account of Grossheim.s (1962) data.
