Impatiens nushanensis (Balsaminaceae), a new species from Yunnan, China

Abstract

Impatiens nushanensis (Balsaminaceae), a new species from Yunnan, China, is described and illustrated here. The new species is morphologically most similar to I. purpurea, but differs by having two pairs of lateral sepals and deep purple lower lobe of the lateral united petal with an acuminate and ribbon-like apex. Furthermore, phylogenetic analysis based on molecular data also support the recognization of this new species.
