Scale:

1:20,000,000.

Accuracy of map:

Map was created using data from herbarium specimens and maps of scale 1:10,000,000.

The projection:

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

Basic content:

Map is a vector file consisting of a polygon and points. Locations of the species are represented by points, while the area of possible distribution of the species is represented by a polygon.

Accuracy of qualifier:

Light-colored points represent species locations referenced in published sources. Dark-colored points represent locations from which herbarium samples were taken. Polygon is based on generalized information from published sources, herbarium specimens, political boundaries and ecological descriptions.

Method of map construction:

Within the former USSR, the species grows in hilly meadows of the Caucasus and is distributed practically everywhere throughout the Caucasus, except for the subtropics, dry woods and mountain steppes. The species distribution area was constructed using herbarium data (VIR and BIN) and published data (Grossheim, 1952; Galushko, 1980; Shishkin, 1948; Cherepanov, 1995). Actually, within the former USSR, there is a northeastern area in which the species is believed to have originated.
