Abstract: The paper is a report on the revised system of the genus Salsola L. by V. Botschantzev and certain problems of the origin, differentiation and distributions of the genus Salsola.#br#The genus Salsola L. comprising 27 species in northwestern deserts of Chiaa, is grouped into 6 sections:Sect. Caroxylon (Thunb.) Fenzl, Sect. Malpigipila Botsch., Sect. Cardiandra Aellen, Sect. Arbuscula Ulbrich, Sect. Coccosalsola Fenzl an Sect. Salsola. The most ancient section, Sect, Caroxylon is assumed to originate as early as in the Oligocene Miocene on South Africa. In the Pliocene it penetrated into the region of Red Sea and the process of intense speciation occured there gave bosth the fruticose species of the sections Malpigipila, Belanthera, Arbuscula and Coccosalsola. Later in Asia, a new period of intense speciation resulted in the origin of annual species of the above mentioaed sections, as well as the sections Cardiandra and Salsola comprising only annual species.
