Abstract

Begonia qingchengshanensis H.Z. Li, C.-I Peng & C.W. Lin, a new species of sect. Reichenheimia from Qingchengshan, an important centre of Daoist religion in Sichuan Province, China and a World Heritage Site, is here described and fully illustrated. Begonia qingchengshanensis resembles B. wilsonii Gagnep., also a member of sect. Reichenheimia occurring in Sichuan, in the widely ovate leaves and 3-locular ovary, each locule with unilamellate placenta. The new species differs from B. wilsonii in having an erect stem (vs. stemless with basal leaves) and ovary trigonous-ellipsoid with 3 wings (vs. clavate and without wings).
