Basic contents:

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

Accuracy of the qualifier:

The dots represent information on the species localities: 1 - reliable data from herbarium and published sources; the polygon (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 map of a part of the species distribution range (Polozhij, Malyshev, 1952) and published data (Bobrov, 1945; Pavlov, 1961) were used for constructing the range of Trifolium eximium. The range consists of one polygon and dots. The species is restricted in Altai mountains, southern East Siberia and southern Far East.
