Scale:

1:20,000,000.

Accuracy of map:

Map was created using information from state publications and maps of scale 1:5,000,000-1:80,000,000.

Projection:

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

Basic content:

Vector map. Main distribution area is shown by a polygon, while sporadic distribution is shown by points. Zone of weediness is shown by a polygon.

Accuracy of classifier:

Distribution area of the species is divided into zones of main distribution, sporadic distribution, and weediness.

Mapping procedure:

Distribution area and zones of weediness were outlined following an analysis of public cartographical materials and state publications. The area of distribution was created using the map of E. Hulten & M. Fries (1986). Disjunctive areas of distribution in the European region and the Caucasus were finally united after including the Stavropol and Krasnodar Territories in the area of distribution (as well as the area of weediness) according to published data (Galushko, 1980; Makarova, 1955; Kolpikova, 1975; Ul.yanova, 1990). The species has been found in the agricultural zone of Kyrgyzstan (Sukhin, Moiseeva, and Vasyuta, 1983), where its distribution area was coordinated with the area of arable lands. The species distribution area in the Far East was outlined using Kharkevich.s (1992), data from Tolmachev (1966), and data from the BIN Herbarium. The distribution area was supplemented with points of sporadic distribution mentioned in herbarium and published data (Maevskii, 1954; Nabiev, 1960; Nikitina, 1955; Rasin.sh, 1987; Tolmachev, 1966; Pavlov, 1965). The zone of weediness was drawn in accordance with published data. The zone was repeatedly reported as having a species occurrence of 23-29% (Ladan, 1990) or as being an area in which G. parviflora is either a malignant (Samersov, Padenov, and Soroka, 2000; Stantsyavichus, 1958; Ul.yanova, 1990) or a harmful weed (Samersov, Padenov, and Soroka, 2000; Kolpikova, 1975) in different districts.
