The flora of China is well known for its high diversity and endemism. Identifying centers of endemism and designating conservation priorities are essential goals for biodiversity studies. However, there is no comprehensive study from a rigorous phylogenetic perspective to understand patterns of diversity and endemism and to guide biodiversity conservation in China. We conducted a spatial phylogenetic analysis of the Chinese angiosperm flora at the generic level to identify centers of neo‐ and paleo‐endemism. Our results indicate that: (i) the majority of grid cells in China with significantly high phylogenetic endemism (PE) were located in the mountainous regions; (ii) four of the nine centers of endemism recognized, located in northern and western China, were recognized for the first time; (iii) arid and semiarid regions in Northwest China were commonly linked to significant PE, consistent with other spatial phylogenetic studies worldwide; and (iv) six high‐priority conservation gaps were detected by overlaying the boundaries of China's nature reserves on all significant PE cells. Overall, we conclude that the mountains of southern and northern China contain both paleo‐endemics (ancient relictual lineages) and neo‐endemics (recently diverged lineages). The areas we highlight as conservation priorities are important for broad‐scale planning, especially in the context of evolutionary history preservation. Identifying centers of endemism and designating conservation priorities are essential goals for biodiversity studies. A spatial phylogenetic analysis of Chinese angiosperms identified nine centers of endemism in mountainous regions; arid and semiarid regions in northwest China were linked to significant phylogenetic endemism. These areas are important conservation priorities.
