Accuracy of the map:

The map is based on 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; 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, and published data (Grossheim, 1945, 1952; Sinskaya, 1950; Vassilchenko, 1987) were used for constructing the range of Trigonella foenum-graecum. The species range consists of three polygons and dots. The first polygon is situated in Transcaucasia, the rest in the mountain part of Central Asia. There are three centers of natural occurrence of the species, described in the former USSR: Nakhichevan, mountain Turkmenistan and Tajikistan. Dots beyond the polygons represent specific localities of the species where it was cultivated and then naturalized.
