The family Chenopodiaceae in the flora of Kalmykia occupies the third place in terms of the number of species after Poaceae and Asteraceae and fifth in the number of genera. The leading genera in the family are: Atriplex L., Salsola L., Chenopodium L., Suaeda Forssk., Petrosimonia Bunge. The article provides an analysis of the species composition of the Chenopodiaceae family according to the types of areals, in relation to salinization of the substrate, according to ecobiomorphological features. Within the family, different ecological plasticity of species and a high specialization of adaptations to the conditions of desertification of Kalmykia are noted: microphilia, halophylicity, affinity, ability to overheat and high solar insolation, summer rest and late summer-autumn or less early spring vegetation.
