Abstract: With the accumulation and accessibility of information about plant species, it is time to re-evaluate and further divide a global biodiversity hotspot region, Yunnan, located in southwestern China. In this study, we combined data on the distribution of 1010 stenochoric endemic seed plants, vegetation constitution, geological history and climate change, and used these to propose a new system of floristic regions. We identified 11 distinct floristic subregions and 84 floristic provinces within Yunnan. Our work confirmed some views emphasized by Wu Zhengyi that the stenochoric endemic species play a key role in defining floristic provinces; that stenochoric endemic plants with long collection and publication histories are more valuable; that greater attention should be paid to woody plants; and that for Yunnan, a border region, some trans-border distributed elements should be treated cautiously.
