[Objective] This paper reports the first occurrence of Habenaria trichosantha Lindl. (Orchidaceae) in China. Detailed anatomic photos of its blooming period are provided and the differences with its morphological close relatives are summarized. [Methods] Morphological observations were conducted based on the live individuals of domestic wild populations, and the main taxonomic features were photographed and recorded. [Results] H. trichosantha Lindl. was only recorded in the Eastern Himalayas and Indo-China Peninsula historically, which has been found in the Savanna ecosystem of Nujiang dry-hot valley, Western of Yunnan Province, it can be easily distinguished by its fan-shaped lip lateral-lobes with long and branched fringes from other species of the same genus. [Conclusion] H. trichosantha Lindl. is a newly recorded species in China, and this discovery further enriches the resources of wild orchids in China.
