///In this paper, the characteristics of the distribution of Permian floras in Tibet is summarized and discussed. On the basis of the analysis of the floral components and characters, Permian paleophytogeographical provinces can be divided into three units in Tibet: the northern fringe of Gondwanan floral province of the southern Tibet (the Himalayan region), the Cathaysia—Gondwana floral transitional province of the central Tibet (the Gangdise—Nyainqentanglha region) and Cathaysian floral province of the northern Tibet (the Tanglha region).
