Impatiens plicatisepala C. Y. Zou, Yan Liu & S. X. Yu (Balsaminaceae), a new species from Ziyuan County Guangxi, China, is described and illustrated. It is closely related to Impatiens davidii Franchet and Impatiens dicentra Franchet ex J. D. Hooker, all of them having 1-flowered inflorescence and basal lobe of lateral united petals with a filamentous hair. This new species has unique characters and differs from its relatives by plicated sepals, rugose seeds and two bracts in different shapes.
