Date of creation:

Scale:

1:20 000 000.

Exactness of the map:

Map is based on data from herbarium specimans and on maps having the following scale 1:15 000 000 - 1:60 000 000.

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 the classifier:

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

Method of map production:

Species location data were obtained from a database of site coordinates of the species in the INFORMATION RETRIEVAL SYSTEM " Wild-growing relatives of cultural plants of Russia " (NTC "Informregistr" № 0229905883, 1999) and from maps published by M.P.Zhukovsky (1928), A.Eig (1929), M.W. van Slageren (1994).
The species has a disjunctive area. In the Crimea, in the Caucasus and in the Middle Asia borders of the area were constructed in accordance with map published by M.W. van Slageren (1994) and were corrected using the material of seed collection and herbarium WIR (this information are kept in a database IRS). In the Black-sea part of the USSR (Taman peninsula) borders of the area were drawn using the material of seed collection and herbarium WIR.
