Abstract:?Located in the southern part of Hengduan Mountains, northwest Yunnan is one of the world’s biodiversity hotspots. However, despite its rich plant diversity, the region has been understudied as a locus for plant data acquisition, especially when it comes to county level. In this study, we built a catalogue of county-level seed plants in northwest Yunnan by reference to the latest molecular systematics and taxonomy, based on an integrated study of existing literature (including floras, fieldwork reports, monographs, and other scholarly works), specimen archives and public databases. This dataset is a checklist of 5,866 seed plant species from 16 counties of northwest Yunnan, including seven information categories, namely, order name in Latin, order name in Chinese, family name in Latin, family name in Chinese, scientific name, Chinese name, and county-level distribution data. It has practical value for the conservation of rich seed plant species in northwest Yunnan.
