Abstract

Impatiens hekouensis, a new species from Hekou County, Yunnan Province, China, was described and illustrated based on morphological and molecular evidence. This new species is morphologically similar to I. balansae, but can be distinguished by the densely pubescent stem, and different shapes of lower sepal, dorsal petal and lateral united petals. Phylogenetic analyses were carried out using the nuclear ribosomal ITS sequence and the chloroplast atpB-rbcL spacer sequence, and the results further confirmed the close relationship between I. hekouensis and I. balansae.
