Accuracy of the map:

The map is based on data of a 1:10 000 000 scale map, corrected according to herbarium materials.

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 is distributed in the Crimea, in broad-leaved montane forests. The species range is represented by a polygon embracing the species localities in the southern, mountain part of the Crimea. Factual materials of LE, WIR and MW Herbaria made the base of the species range construction. Two species closely related to the discussed one, L. litvinovii Iljin and L. miniatus M.B., poorly distinguishable in herbarium and nature, are included by some taxonomists in L. rotundifolius. These species, however, have specific characteristics, different ranges (the former one is distributed in the South Ural and in the southern Volga-Kama floristic region, the latter in the Caucasus - Ciscaucasia, Transcaucasia and Dagestan) and are separate species.
