Impatiens chashanensis H. Y. Bi & S. X. Yu (Balsaminaceae), a new species from the Sichuan Province in China, is described and illustrated. In comparison with the morphologically close I. dicentra , both species have succulent stems and the lobes of the lateral united petals end in a long hair, but I. chashanensis differs in having white flowers, four lateral sepals, lacerate apex of the inner sepal, shorter spur with swollen, slightly bifid apices. Moreover, leaf epidermal characters also support the recognition of the new species.
