Basic contents:

The map is a vector file consisting of 1 basic and 1 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, published data (Bobrov, 1945, 1987) and data from ILDIS World Database of Legumes (Roskov et al., 2005) were used for constructing the range of Trifolium rubens. The range consists of three polygons and dots. The first polygon is situated along the former western border of the USSR, the second one is located in the Central Ukraine (Cherkassy Region), and the third covers the Crimea.
