Abstract [Objective] A newly recorded orchid species, Gastrodia exilis Hook.f., was spotted from Yunnan Province, China, and its main characters were compared with its morphologically close relatives G. menghaiensis Z.H. Tsi & S.C. Chen, G. putaoensis X.H. Jin and G. dyeriana King & Pantl. [Methods] Morphological and anatomical observations of wild population specimens of the above species were carried out using a stereomicroscope, and photographs were taken with a close-up lens attached digital camera. [Results] G. exilis Hook.f. could be easily distinguished from those species by having a lip free of perianth tube, a disk with two conspicuous triangular lamellae near apex, and lobes of perianth tube crisped. [Conclusion] G. exilis Hook.f. is a newly recorded orchid species in China, and the discovery expands its distribution area and enriches the resources of wild orchids in China.
