Scale:

1:20 000 000.

Accuracy of the map:

The map is based on data of 1:13 000 000, 1:20 000 000, 1:80 000 000 scale maps, specified according to herbarium materials.

Projection:

Basic contents:

The map is a vector file consisting of 1 basic and 2 subject layers. The species range is represented by polygons and dots.

Accuracy of the qualifier:

The dots represent information on the species localities: 1 - reliable data from herbarium and published sources; polygons (1) - generalized information on the species distribution from published sources and herbarium specimens.

Method of the map construction:

The data from the herbarium materials of LE and WIR, published data (Bobrov, 1945, 1987), published maps of the species range (Hulten, Fries, 1986) and parts of the range (Grossheim, 1952; Polozhij, Malyshev, 1994), were used for constructing the range of Trifolium arvense. Our view on the species distribution in Russia and adjacent states mainly agrees with the concept of the species distribution of Hulten and Fries (1986). We have somewhat extended the polygon borders eastward, on the base of herbarium published data (Bobrov, 1945), and the published map of as part of the species range (Polozhij, Malyshev, 1994). The range consists of the basic polygon covering all the European part of the former USSR (except for the north and southeast), Crimea, Caucasus, central West and southern Central Siberia, northeastern Kazakhstan; of the additional polygon to reflect a local site of the species occurrence in the Southwestern Kopet-Dagh, and dots. Dots outside the polygons characterize isolated localities, mainly in the north, along river courses. The species localities in the Far East are also of adventive nature.
