Scale:

1:20.000.000.

Accuracy of map:

Map is based on data from herbarium specimens and on maps having the following scale: 1:25.000.000-1:40.000.000

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. Points represent recorded locations of the species; polygons represent area of possible distribution of the species.

Accuracy of the 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. Location and area of distribution of the species is based on published maps made by Grossheim (1952) and database information obtained from the herbarium of the N.I. Vavilov Institute. 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.
