Basic contents:

The map is a vector file consisting of 1 basic and 2 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 published sources (2), the polygon - generalized information on the species distribution.

Method of the map contruction:

The range map is based on published maps (Grossheim, 1939). The species is a local endemic, with a range limited by calcareous rocks of the Black Sea coast between Anapa and Gelendzhik towns. N.N.Tzvelev (1976) includes in A.pinifolium also A.karadaghense Kotov, which is distinct by dense villous pubescence of spikelets, but Yu.N.Prokudin treats the latter as one of the forms of A.ponticum widespread there and variable in its traits.
