Accuracy of map:

Map was created using maps of scale 1:2,000,000-1:11,250,000.

Projection:

"Alber.s Equal Area Conic for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic contents:

Vector map consisting of 1 base and 3 thematic layers. The distribution area of the species is shown by polygons and points.

Accuracy of qualifier:

Points represent locations from which L.E. herbarium materials were taken and locations mentioned in published references. The polygon is based on generalized information on species distribution.

Mapping procedure:

The species distribution area was determined using species locations reported by the L.E. herbarium and published maps from Malyshev & Peshkova (1990), Tolmatchev (1974), and Hulten & Fries (1986). The species distribution area covers the entire Arctic zone within the former USSR and the high-mountainous belt of Central Asia. Hulten and Fries (1986) consider Festuca richardsonii part of a complex of kriophil forms of Festuca rubra s.l., which incliudes F. cryophylla, F. kirilovii and some other species. The Soviet authors consider these subspecies of F. rubra - Festuca rubra subsp. arctica (or a special species Festuca arctica).
