Scale:

1:20,000,000.

Accuracy of a map:

Created using maps of scale 1:12,000,000-1:40,000,000.

Projection:

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

Basic contents:

Vector map. The area of species is designated by a polygon.

Accuracy of classifier:

Species distribution is based on location coordinates of germplasm accessions and herbarium specimens of the N.I. Vavilov Institute and published maps from: Grossgheim (1939); Buhteeva (1990) and Ivanov & Buhteeva (1975).

Method of map production:

Published literature was reviewed, including atlases, monographs and papers. Occurrence data were obtained from herbarium specimens, floras, monographs and papers. Data were then compiled through scanning and geo-referencing to develop a composite vector map. The biologist, together with the GIS specialist, drew a new plant distribution area based on compiled data.
