Scale:

1:20 000 000.

Exactness of a map:

The map was created using maps that had 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:

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

Exactness of classifier:

Light-colored points are locations referenced in literature sources. Dark-colored points are locations of the species that were as reported from created database VIR (N.I.Vavilov All-Russian Research Institute of Plant Industry) and BIN (the Komorov Institute of Botany).Polygons are based on literature sources, herbarium samples, political boundaries and ecological description.

Method of map construction:

For construction of the area of Trifolium trichocephalum the published map of area (Grossheim, 1952) and herbaria data (Komarov Botanical Institute (BIN), N.I. Vavilov All Russian Institute of Plant Industry (VIR), St.-Petersburg) were used. According to literary data the species has distributed across whole Caucasus territory excluding Talysh (Flora of the USSR, 1945; Flora of Azerbaijan, 1954; Brezhnev, Korovina, 1980).The presented area created by data generalization is the polygon (green line). The definition of area border is based on all available data which have no significant contradictions.
