Abstract:In order to species identify of Hedychium flavum complex, the morphological characteristics of specimen collected from Guizhou, Chongqing, Sichuan, Yunnan, Guangxi, and transplanted plants were observated. The results showed that the characteristics of floret aroma, ligule, bracts, labellum, lateral vestigial stamens and fruits were important indexes for species identification of H. flavum complexes. Then H. panzhuum Z. Y. Zhu was classified into H. flavum Roxb., and H. emeiense Z. Y. Zhu into H. chrysoleucum Hook. rather than H. flavescens. It was suggested that there were 4 species in H. flavum complex, including H. flavum Roxb., H. bipartitum G. Z. Li, H. chrysoleucum Hook. and undescribed species Hedychium sp.
