During our field trips to Hainan Bawangling National Natura Reserve,Gastrodia punctata Aver.,a newly recorded species of Gastrodia from China,was discovered and here reported. This species was previously considered as endemic to Vietnam. Its Chinese epithet was entitled by the meaning of specific epithet and morphological characters. It could be identified from other species of this genus by the brown sepals with numerous lager white spots,four keels on the lip and the falcate stigma located at the base of column. In this paper,its Chinese description,color illustrations,distribution and conservation status were provided as well.
