This paper describes and illustrates the morphological traits of Impatiens zhaojueensis Q. Luo (Balsaminaceae), a new species from the Sichuan Province of southwestern China. Using a scanning electron microscope (SEM), the micromorphological characteristics of its pollen grains and seeds are also described. The new species is closely related to Impatiens baishaensis, but it has larger flowers, obround dorsal petals, somewhat clawed lateral united petals, obround or obround‐dolabriform distal lobes and the ornamentation on the pollen grains has wider meshes.
