Scale:

1:20 000 000.

Accuracy of the map:

The map is based on data of 1:13 000 000, 1:80 000 000 scale maps, 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 and WIR, published data (Bobrov, 1945, 1987; Nikitin, Geldikhanov, 1988), published maps of the range (Hulten, Fries, 1986) and of the range part (Grossheim, 1952) were used for constructing the range of Trifolium bonannii. Our view on the species distribution in Russia and adjacent states mainly agrees with the treatment of the species distribution by Hulten and Fries (1986). The range consists of five polygons and dots. Three polygons cover western and southern Ukraine, Crimea, Caucasus. The remaining two polygons are in the mountain massifs of Central Asia. Dots beyond the polygons represent specific localities of the species.
