Basic contents:

Map is a vector file consisting of points. Locations of species are represented by points.

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).

Method of map construction:

For construction of the area of Trifolium incarnatum the published map of the part of the area (Grossheim, 1952) and herbaria data (Komarov Botanical Institute (BIN), N.I. Vavilov All Russian Institute of Plant Industry (VIR), St.-Petersburg) were used. The species has originated from the West Europe and Mediterranean basin and its. locations at the territory of European part of the former USSR, the Caucasus and the Crimea represent the the secondary area of the species. The secondary area of the species appeared to be formed as a result of men activity, introduction and former naturalization of the species (Brezhnev, Korovina, 1980). The species could naturalize at the maritime areas of the Crimea and the Caucasus. The presented area created by data generalization are separate points. The definition of area is based on all available data - determined species locations and literary data (Flora of the USSR, 1945; Flora of the European part of the USSR, 1987), which have no significant contradictions.

Sources of the data:
