Accuracy of the map:

The map is based on data of 1:12 000 000-1:40 000 000 scale maps.

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 3 subject layers. The species range is represented by a polygon and dots.

Accuracy of the qualifier:

The dots represent information on the species localities according to herbarium materials of LE (1) and published sources (2), the polygon - generalized information on the species distribution.

Method of the map contruction:

The range map is based on coordinates according to herbarium materials of V.L.Komarov Botanical Institute (LE) and published maps (Shelyag-Sosonko, 1977). The species range covers mountains and piedmont of Crimea. Sometimes is treated within an ancient Circumpontic species Agropyron brandzae Pantu et Solacola, the latter embodying A.brandzae, A.ponticum, A.pinifolium; however, these species are more likely comparatively young separate taxa, which have formed convergently under similar ecological conditions on the base of A.pectinatum.
