Accuracy of the map:

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

Projection:

"Albers Equal-Area Conic Projection for USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0

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; the 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, a published map of a part of the species range (Grossheim, 1952) and published data (Bobrov, 1945, 1987) were used for constructing the range of Trifolium leucanthum. In the former USSR, the species occurs in the Southern Crimea and Ciscaucasia. The range consists of 2 polygons and dots.
