Basic contents:

The map is a vector file consisting of a polygon and dots. Point localities of the species are represented by dots, the area of possible species distribution is represented by the polygon.

Accuracy of the qualifier:

Dark dots represent information on the species localities from herbarium specimens, the rest (light) dots represent data from published sources; the polygon is based on generalized information from published sources and herbarium specimens.

Method of the map construction:

The species distribution is limited by sands of Caspian Lowland and beach sands of the Caspian Sea coast. The range is represented by a polygon, which includes a set of the species localities on the northeastern coast of the Caspian Sea. The southern polygon border coincides with the coastline of the Caspian Sea. The northern, eastern and western outlines of the polygon are drawn on the basis of generalized available information on the species distribution. The dots outside the outlines represent adventive species localities. The herbarium materials of LE, MW and MHA were used for the range construction, as well as published maps of the species range (Grossheim, 1952; Ivanov et al., 1986), and information from published sources (Galushko, 1980; Bobrov, 1945).
