Date of creation:



1:20 000 000

Accuracy of the map:

Map was created based on data from herbarium specimens and specified on maps having the following scale - 1:10 000 000.

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 and 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 following sources were used to determine the area of distribution of this species: Moscow State University herbarium, V.L. Komarov Botanical Institute herbarium, Galushko (1980), Cherepanov (1995), Bobrov & Tsvelev (1990), Grossheim (1948), Kolakovsky (1982). The area is presented along the narrow range extended in a longitudinal direction, along the frontier of former USSR, from the north of the Crimean peninsula (its southern part) up to the foot of the Big Caucasian ridge. As the basic part of the area is in the territory of Southern Europe, Northern Africa and Asia, the area were it is distributed in the former USSR represents the northeast edge of the geographic distribution of the species. The points which were not included into borders of the range demonstrate individual habitats of the species that are quite typical for the species; it can be found as a weed plant along roads and near settlements in the south of the European part of former USSR. Data were 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.
