Systematic and bioecological Gypsophila L. characteristic in Azerbaijan flora

Data on the systematic composition and bioecological features of the genus Gypsophila L., Caryophyllaceae. Life forms, ecological features, geographic range and endemism of species are compared. G. tenuifolia M. Bieb. (Caucasus), G. stevenii Fisch. ex Schrank (Caucasus), G. robusta Grossh. (Caucasus), G. acutifolia Fisch. (Kazakhstan). Caucasian endemics: G. capitata M. Bieb., Gypsophila lipskyi Schischk., G. szovitsiana Lazkov species are subendems of Azerbaijan. Analysis of subendemic and endemic species of Gypsophila L. genus showed that the ranges of the species are of European and xerophilic origin. This indicates that Turkey has an older florogenetic relationship with centers of xerophilous flora.
