Basic content:

Map is a vector fail consisting of polygon and points. Locations of species are represented by points, area of possible distribution of species are represented by polygon.

Accuracy of the qualifier:

Points are locations of species that were reported from herbarium samples of Komarov Botanical Institute (St.-Petersburg) .

Method of map construction:

Location and area of distribution of the species is based on analysis of herbarium materials from Komarov Botanical Institute (St.-Petersburg) and the literary data, which include the concrete places of growth of species (the Determinant of plants of Central Asia, 1972), were used. The area of species consists of the basic big range, which includs overwhelming majority of species sites, and the small range, which includes species sites on the territory of Fergana valley, isolated from different directions by mountain ridges. The species is characterized in the distribution by narrow ecology-geographical arranging to salted soils, clays and to rubble of deserted and deserted - steppe plains. In this connection northern and northwest borders of its distribution are limited to a zone of distribution Kazakh small-shaped hills and Near-Caspian deserts. In a southwest part of area the species does not come for limits of Syr-Darya, in the West distribution of species is limited by Caspian Sea.
