Scale:

1:20,000,000.

Exactness of map:

The map was created using maps of scale 1:25,000,000.

The projection:

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

Basic contents:

Map is a vector file consisting of polygons and points. Locations of the species are represented by points, while the area of possible distribution of the species is represented by polygons.

Exactness of classifier:

Light-colored points represent species locations referenced in published sources. Dark-colored points represent species locations reported in the BIN database (Komarov Botanical Institute) and the VIR database (N.I. Vavilov All-Russian Institute of Plant Industry). Polygons are based on published sources, herbarium samples, political boundaries and ecological descriptions.

Method of map construction:

To construct the distribution area of Phalaroides japonica, a published map of species distribution (Malyshev & Peshkova, 1990) and herbaria data (Komarov Botanical Institute (BIN), (St. Petersburg), N.I. Vavilov All-Russian Institute of Plant Industry (VIR), St. Petersburg) were used. The final species distribution area is represented by three polygons (green line) and corresponds to published data on species distribution (Tzvelev, 1976; Brezhnev & Korovina, 1981). The distribution area borders take into account the ecological preferences of the species.
