Basic contents:

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

Accuracy of qualifier:

Points represent species locations referenced in published literature and original locations of L.E. herbarium specimens. The polygon was constructed using generalized information on species distribution.

Mapping procedure:

The map is based on species locations provided by the L.E. herbarium and published maps from Grossheim (1939). The species is distributed throughout the zone of dry and desert steppes. In the Caucasus, the Lower Volga region and Western Kazakhstan, the more prominent species is actually Catabrosella humilis subsp. Humilis. In Eastern Kazakhstan (Balkhash region and foothills of Tien Shan), the subspecies C. humilis subsp. songorica Tzvel is more prominent.
