Scale:

1:20 000 000.

Accuracy of the map:

The map is based on data of 1:20 000 000, 1:25 000 000 scale map, 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 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 collections of LE and WIR, the rest (light) dots represent data from published sources.

Method of the map contruction:

General distribution of the species comprises the Caucasus, Central and Atlantic Europe, Mediterranean, Asia Minor. The northeastern part of the species range is situated in the former USSR. We follow the view of Z.V.Chefranova (Fedorov, Tzvelev, 1987) on the species distribution in the former USSR, and consider the species distributed in the Caucasus, Crimea, in the Carpathian, Moldavian and Black Sea regions of the European part of the former USSR, and southern Russia. The species range is represented by two polygons, European-Caucasian and Crimean, as well as separate dots. The European polygon is drawn according to factual (LE and WIR Herbaria) and published (Shishkin, Bobrov, 1948; Fedorov, Tzvelev, 1987; ILDIS) data by means of their generalization. The Crimean polygon embraces the species localities in the southern, forest part of the Crimean Peninsula and is drawn according to data of LE and WIR Herbaria. The borders of the Caucasian polygon are drawn after published (Galushko, 1980; Grossheim, 1952) and factual (LE and WIR Herbaria) data.
