Abstract
Sorbus lushanensis Xin Chen & Jing Qiu, sp. n. (Rosaceae), a new simple-leaved species belonging to Sorbus subg. Aria sect. Alnifoliae, is described from Anhui and Jiangxi provinces in China. Illustrations, photographs of wild plants and a distribution map are presented. The new species is morphologically similar to S. folgneri, but can be distinguished easily by its abaxially greenish-grey tomentose leaves, scale-like stipules and glabrous styles.
