Basic contents:

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:

Light-colored points are locations referenced in literature sources. Dark-colored points are locations of species that were reported from herbarium samples of V.L.Komarov Botanical Institute [LE] and N.I.Vavilov All-Russian Institute of Plant Industry [WIR]. Polygon is based on generalized information from literature sources, herbarium specimans, political boundaries and ecological description.

Method of the map construction:

The range of Lathyrus sylvestris is drawn by means of generalization of data available and includes points of the species localities in the European part of the former USSR and the Caucasus (Ciscaucasia and Transcaucasia). The species distribution is determined by its ecological preferences - it occurs in forest fringes, meadows, among shrubberies. The northern limit of the species range reaches the Dvina-Pechora region. In the east the distribution is limited by Ural mountains, in the south by dry steppes and deserts. The western border of the range outline coincides with the state boundary of Russia. The dots outside the contour represent alien localities of the species related to anthropogenically disturbed areas since the plant is sometimes cultivated as ornamental. For the map construction, the herbarium materials (LE, WIR) and published maps of the range (Hulten, 1986) were used.
