The floristic composition of pistachio-woodland (Pistacieta atlantici) of Georgia (South Caucasus) is studied. 250 species of vascular plants, which belong to 174 genera and 50 families, were recorded. Floristic structure, composition of chorotypes and life forms are commented. Based on the systematic structure of this flora and composition of chorotypes, 3 the main directions of florogenetic connections are identified: 1. South-West Asia, 2. Mediterranean, 3. Eurasian steppe. Attenuated form shows the impact of Iran-Turan deserts and connections to Europe. It was found that the formation of pistachio-woodland of Georgia was implemented in the bosom of Ancient Mediterranean with close contact with the boreal flora. Connection with savannas is not observed.
