Impatiens baokangensis Q.L. Gan & X.W. Li, sp. nova (Balsaminaceae) is described from Baokang County, Hubei, China. It is similar to I. compta, but differs from it by distinct cristae on the abaxial surface of the dorsal petal (versus long rostrum at apex of dorsal petal), lower sepal that is concave at base (versus lower sepal protruding at base), and lower petal of lateral united petals being clawed (versus not clawed). Impatiens baokangensis is also somewhat similar to I. nasuta, and the distinguishing features include an abaxial midvein on dorsal petals with semi-circular cristae in I. baokangensis versus an arcuate, long rostrum in I. nasuta, wider upper petal of lateral united petals in I. nasuta, and longer capsules in I. baokangensis. Over 10 000 scattered individuals of I. baokangensis were found in a roadside ditch and at forest margins at the type locality.
