Date of creation:

20.09.2005.

Scale:

1:20,000,000.

Exactness of map:

Map was created using location from which herbarium specimens were taken and maps to the scale of 1:17,000,000 - 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; area of possible distribution of species is represented by polygons.

Accuracy of classifier:

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

Method of map production:

Species location data were obtained from a database of site coordinates of species location (N.I. Vavilov Institute, 1999); from a map published by Ju.N. Gorbunov, G.G. Postovalova, and G.I. Serykh in "Areas of distribution of medicinal plants and their relatives in the USSR" (1990); and from a map published by Moesel (1965). The species has a disjunctive area. The borders of the European part of the area were constructed according to map published by Ju.N. Gorbunov, G.G. Postovalova, and G.I. Serykh (1990). Northern, eastern and southeastern borders of the Caucasian part of the area were likewise drawn according to the map published by Ju.N. Gorbunov, G.G. Postovalova, and G.I. Serykh (1990) and were corrected using information regarding herbarium specimens from the IRS database. The southern border was constructed according to the map published by Moesel (1965). In the final mapped distribution area, we did not include points isolated from the general distribution area of the species in Eastern Transcaucasia based on the map published by Moesel (1965).
