The Xizang Autonomous Region, the provincial administrative region with the second largest land area in China, is located on the vast Qinghai-Tibet Plateau, which, in addition to being the tallest and largest plateau in the world, is also an incredibly rich biodiversity hotspot, supporting a variety of ecosystem. Initial efforts by research groups in the 1980’s to elucidate the full extent of plant diversity in this region has been described previously in the book series Flora Xizangica, however the collection of records of plants in southern Xizang remains largely incomplete in this work. The study presented here compiles information extracted from floras, periodical literature, dissertations, collected specimens from field surveys, and the Plant Photo Bank of China (PPBC) to provide an updated dataset of vascular plants in all of Xizang. Each record in this dataset represents the distribution of taxonomic groups at the county or city level and includes the following: category, survival status, Chinese family name, Latin family name, Chinese genus name, Latin genus name, Chinese species name, Latin species name, authors of the Latin species name, county or city level distribution, literature evidence, literature notes, specimen evidence, etc. Based on this new dataset, we archived a list of vascular plants of Xizang. As of August 2023, this checklist contains 11,853 taxa across 252 families and 2,049 genera of vascular plants, including 50 taxa belonging to 2 families and 7 genera of lycopods, 699 taxa belonging to 31 families and 110 genera of pteridophytes, 84 taxa belonging to 6 families and 19 genera of gymnosperms, and 11,020 taxa belonging to 213 families and 1,913 genera of angiosperms. From this data we identified the top 10 families possessing the highest number of species in this region (Asteraceae, Orchidaceae, Poaceae, Fabaceae, Rosaceae, Ericaceae, Ranunculaceae, Lamiaceae, Primulaceae, and Apiaceae). Finally, we also generated a checklist of vascular plants with excluded/dubious records in Xizang, which includes 900 species of 454 genera across 121 families. This study will provide an expanded basic background and central framework for the second edition of Flora Xizangica, as well as serve as an important reference for plant diversity conservation and monitoring throughout Xizang forward.
