Topographic Heterogeneity Outweighs Climate in Shaping <i>Artemisia</i> L. Species Richness and Endemism in the Hengduan Mountains, Southwest China.

ABSTRACT: Artemisia L. (Asteraceae) is an important ecological pioneer genus and a widely used medicinal plant group. The Hengduan Mountains (HDMs), one of the most topographically complex regions in the world, support a high diversity of Artemisia species. Understanding the diversity patterns of Artemisia species in this region is essential for conserving plant resources and promoting their sustainable use. In this study, we identified the hotspots of Artemisia species richness and weighted endemism in the HDMs and examined how these patterns relate to topographic heterogeneity. We confirmed the distribution of 114 Artemisia species across the Hengduan Mountains. Our results show clear spatial variation in Artemisia species diversity. Distinct hotspots were
