Scale:

1:20,000,000.

Accuracy of map:

The map was created using maps of scale 1:50,000,000, 1:30,000,000, 1:10,000,000, and 1:5,000,000.

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, while actual location occurrence is shown by points.

Accuracy of classifier:

Point data were obtained from published sources and herbarium specimens. Light-colored points represent species locations cited in published literature. Dark-colored points represent locations from which herbarium materials were taken. Polygons are based on published 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. Point data were compiled from Malyshev & Peshkova (1979, 1990) and the V.L. Komarov Botanic Institute. The final map legend is bi-colored. Dark-colored points represent locations from which herbarium materials were taken. Light-colored points represent species locations cited in published literature. The polygon area data was gathered from the following sources: Tzvelev (1976), Pavlov (1956), and Kovalevskaja (1968). The polygon is the result of integrating maps of species distribution in Middle Asia with data from Tzvelev (1976), Pavlov (1956), and Kovalevskaja (1968) and the state border of Russia. Distribution in Siberia was determined using Malyshev & Peshkova (1979, 1990), original locations of the specimens at the herbarium of the V.L. Komarov Botanical Institute and the state border of Russia. 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.
