Hedychium wangmoense F.J. Mou & X. Hu (Zingiberaceae), a new species from southwest Guizhou Province, China, is described and illustrated, including the information on its phenology, distribution, habitat, and conservation status. Hedychium wangmoense is morphologically most similar to H. forrestii by having involute bracts, large labella and wide lateral staminodes, but can be distinguished from it by its orange-pink and faintly fragrant flowers (vs. white and fragrant flowers), longer corolla tubes, wider lateral staminodes, larger labella, longer stamens, as well as glabrous bracts (vs. pilose bracts). A key to species of Hedychium in China is also provided.
