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, published map of the range part (Grossheim, 1939; Hulten, Fries, 1986; Shelyag-Sosonko, 1977), and published data were used for constructing the range of Bromopsis benekenii. Our view on the species distribution in Russia and adjacent states mainly coincides with the treatment of the species distribution by Hulten, Fries (1986). We have somewhat extended the borders of the polygons on the basis of herbarium materials and published data (Fedorov, 1974; Pavlov, 1956; Rozhevits, Shishkin, 1934; Tzvelev, 1976). The range consists of 4 polygons and dots. Three small polygons are situated in Crimea, mountain part of Central Asia, and Altai. The largest polygon covers the large part of the European part of the former USSR (except for dry steppes of Ukraine and Russia), Urals, West Siberia. Dots beyond polygon borders represent separate localities of the species.
