Abstract:Gastrochilus setosus Aver. & Vuong was reported as a new orchid record for China. Photographs and a detailed description were provided. The shape of this species is similar to G. raraensis Fukuuama, but the plant is small and the lips have short bristles and other characteristics, which can be easily distinguished from G. raraensis. This species was originally distributed only in Vietnam, and is now found in Tibet, China for the first time. The voucher specimens are deposited in the Herbarium of Xizang Agriculture and Animal Husbandry College.
