Abstract:

 Begonia pellionioides YM. Shui & WH. Chen, a new species of the genus Begonia L. (sect. Petermannia (Klotzsch) A. DC., Begoniaceae), is described and illustrated. The new species is endemic to limestone areas in Southeastern Yunnan Province, China, and is most similar to Begonia hainanensis Chun & F. Chun but distinguished by its more elongated leaves with cuneate base and acuminate to caudate apex, tepals adaxially with spiny hairs and sharply triangular capsulewings with truncate superior margin. Besides, the unknown flower morphology of previously published Begonia sublongipes YM. Shui in Begonia sect. Petermannia is described.

Key words: Begonia, Begonia pellionioides, Begoniaceae, section Petermannia, Yunnan, China
