摘要：

Three new species of Impatiens (Balsaminaceae) from Myanmar are here described: I. decurva Ruchis. & S. B. Janssens, I. hartnolliae Hook. f. ex Ruchis. & Suksathan, and I. oblongata Ruchis. & Van der Niet. The 5-lobed short fusiform fruit of all three species suggests that they are members of subgen. Impatiens sect. Uniflorae Hook. f. & Thomson. For I. decurva and I. oblongata, subgenus membership was corroborated by phylogenetic analyses of a combined dataset of nuclear ITS and plastid atpB-rbcL intergenic spacer DNA sequences. This was not possible for I. hartnolliae, which is only known from a single herbarium specimen.
