Steppe and similar habitats in southern Siberia, Mongolia and adjacent regions harbour a considerable diversity of Taraxacum sect. Dissecta, its taxonomic revision is presented. A thorough study of live and herbarium plants revealed 30 species that belong, or are very close, to T. sect. Dissecta, seven species were known previously and 23 are described as new, mostly from the Altai Republic, Novosibirsk, Irkutsk, Lake Baikal and Bratsk. Their distribution includes the Asiatic part of Russia, Kazakhstan, Kyrgyzstan, Mongolia and Xinjiang, China. The name T. dissectum (Ledeb.) Ledeb. is relegated to the synonymy of T. pubescens (Fr.) Fr. A detailed analysis of the original material of the name T. collinum revealed that it consists of mostly juvenile plants belonging to several species of T. sect. Dissecta, and that it requires further study on newly collected material. The frequently reported occurrence of T. sect. Dissecta (as T. dissectum) in the European mountain ranges was reassessed.
