This paper reports a new record genus of Tibetan orchids——Acanthephippium, and a new record species of Tibetan orchids——Acanthephippium striatum Lindl. The other species is Gastrodia flavilabella S. S. Ying. A. striatum Lindl is similar to Acanthephippium gougahense (Guillaumin) Seidenfaden and Acanthephippium sylhetense Lindl. of the same genus, the main difference is that the latter two have thickened fleshy labial discs and broad and short blunt calyx sacs. The morphology of Gastrodia flavilabella S. S. Ying plant is similar to that of Gastrodia javanica (Bl.) Lindl, which has persistent, triangular floral bracts; rhizomes without coralline roots; and nonspherical callus on the basal claw of the labellum. In the paper, one genus and two species of orchids were newly recorded with photos of the newly recorded features, which enriched the background resources of wild orchids in the region. At the same time, the endangered level is assessed and determined according to the evaluation criteria of IUCN, and the conservation level is proposed. The voucher specimens are kept in the herbarium of the Tibetan Plateau Institute of Ecology (XZE).
