Tibet is rich in orchid plant resources, mainly distributed in the eastern Himalayas. Among them, Motuo County, Bomi County and Chayu County of Nyingchi City, Yadong County, Dingjie County, Nielamu County and Jilong County of Xigaze City are the main distribution areas of orchid plants in Tibet. With the release of Latest National Key Protected Wild Plant List, more and more orchids are listed for protection. In this paper, four species of the Subtribe Goodyerinae (Orchidaceae) found in the southeast of Tibet are reported. They are Anoectochilus, Anoectochilus brevilabris Lindl., Cheirostylis moniliformis (Griff.) Seidenf., Goodyera hispida Lindl and Goodyera yunnanensis Schltr. The voucher specimens are deposited in the Herbarium of Tibet Institute of Agriculture and Animal Husbandry (TAAHUC) and Herbarium of Wuhan Botanical Garden, CAS (WIB). Most of the plants of the Subtribe Goodyerinae have extremely high medicinal value. The report of this new record is of great significance to the introduction, propagation and domestication, biodiversity protection and development and utilization of medicinal Orchidaceae in Tibet.
