| Abstract: |
| Medog, with high diversity of plants species and complicated variety of community types, is the core area of Yarlung Zangbo Grand Canyon National Nature Reserve. Based on literatures review, specimens’ information study, and field investigation, the checklist and catalog of Orchidaceae in Medog, including 89 genera 339 species, were reported. In addition, Liparis pauliana and Nervilia mackinnonii were reported as newly recorded species from Tibet. Calanthe arcuata was reported as newly recorded species from Medog. Morphological descriptions and anatomic figures of new-recorded species were provided, all of which grew under forests at elevations of 2000 m. The study provided an up-to-date checklist and detailed catalog of Orchidaceae and newly recorded orchids species in Medog, which is of high value to understand the orchids resources and flora in Tibet, and even in China and the world, as well as provide important information and basis for the protection, research and scientific utilization of orchids diversity in Medog. |
