Date of creation:

26.06.2004

Scale:

1:20 000 000.

Accuracy of map:

Map was created based on data from herbarium specimens and on maps having the following scale: 1:13 000 000-1:22 500 000.

The projection:

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

Basic contents:

Vector map. Area of species distribution is shown by polygons, actual location occurrence is shown by points.

Accuracy of classifier:

Point data were obtained from literature sources and herbarium specimens. Polygons are based on literature sources, herbarium samples, and field surveys by the authors.

Method of map production:

Published literature was reviewed, including Atlases, monographs and papers. Occurrence data were obtained from herbarium specimens, floras, monographs and papers. The area of general distribution was determined according to the following sources: N.I. Vavilov Institute (1999), Grossgeim (1952) and Sokolov et al. (1980). The species has a disjunctive area. In the European part of the area (Moldova, Ukraine) western and northeast borders of the area were determined based on herbarium materials of the V.L. Komarov botanical Institute and the N.I. Vavilov database (1999) while other borders were determined according to Sokolov et al. (1980). In Crimea the border of the area was determined according to Sokolov et al. (1980) and was adjusted based on herbarium materials of the V.L. Komarov Botanical Institute and the N.I. Vavilov All-Russian Institute of Plant Industry (VIR). In the Caucasus the northern border of the area was determined according to Sokolov et al. (1980). The other borders of this area were determined according to Groosgeim (1952) and Sokolov et al. (1980) and adjusted according to the herbarium materials of the V.L. Komarov Botanical Institute and the database of the N.I. Vavilov Institute (1999). 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.
