Six new records of Orchidaceae in Sichuan Province

During recent investigations in western Sichuan, six species of Orchidaceae were collected, including Tipularia cunninghamii (King & Prain) S. C. Chen, Androcorys ophioglossoides Schltr., Calanthe nipponica Makino, C. taibaishanensis M. Guo, J. W. Zhai & L. J. Chen, Neottia gaudissartii Hand.-Mazz. and N. karoana Szlach., which are new records for Sichuan. Among them, T. cunninghamii is reported on the Chinese mainland for the first time. These records add new components to the flora of western Sichuan and offer new distribution information for studies on the origin and dispersal of these plants.
