A new species of Impatiens L. from Hubei, China, Impatiens zhuxiensis Q.L. Gan & X.W. Li, is described and illustrated. Impatiens zhuxiensis resembles I. nasuta Hook. f. and I. compta Hook. f. and these are the only species in I . sect. Impatiens with a long abaxial rostrum on the midvein of the dorsal petal. However, the flowers of I. zhuxiensis are yellow while those of I. nasuta and I. compta are deep purple‐red and pale purple‐blue, respectively; I. zhuxiensis has the midvein of the dorsal petal abaxially elongated into a pointed rostrum near the apex, whilst the rostrum of I. nasuta is elephant‐trunk‐shaped near the middle, and that of I. compta is recurved near the apex. A molecular phylogenetic analysis of Impatiens based on ITS, atpB ‐ rbcL and trnL‐F supported these three species as closely allied and that they belong to I . sect. Impatiens .
