Impatiens tainingensis J.-D.Lin & P.Li, sp. nov. , is described and illustrated. It was collected from a moist valley of Mt. Zhuangyuanyan, Fujian Province, in Southeastern China. It resembles Impatiens platysepala Y.L. Chen, I. kuocangshanica (X.F. Jin & F.G. Zhang) X.F. Jin & Y.L. Xu and I. huangyanensis subsp. attenuata X.F. Jin & Z.H. Chen in the gross morphology of their pinkish purple flowers but differs in having smaller lateral sepals, subsaccate-funnel form lower sepals, shorter spurs, and capsules. The molecular phylogeny of Impatiens based on plastome and ITS sequences indicated that I. tainingensis is closely related to I. platysepala and I. wuyiensis J.S. Wang, Y.F. Lu & X.F. Jin, but morphology, phylogeny, and plastome structural variation comparison provide evidence for recognizing it as a distinct species.
