Impatiens quintadecimacopii G. W. Hu & Q. F. Wang sp. nov. is described and I. porrecta is reported as a new record from southwestern Yunnan province of China. These two species are close in morphology but can be distinguished by color of flowers, shape of lateral sepals and upper petals, and color of capsules. Morphological characters of these two species indicate they belong to sect. Uniflora in I. subg. Impatiens. Phylogenetic analysis of a combined dataset from nuclear ITS and plastid atpB-rbcL sequences confirmed their close relationship and their phylogenetic placement in sect. Uniflora.
