Abstract
A new species, Chamaegastrodia guidongensis L.Wu, H.Z.Tian & C.Z.Huang from Hunan Province, China, is described and illustrated. The new species is distinct from other Y-shaped and T-shaped lip species of Chamaegastrodia by its unique canoe-shaped lip. It is most close to C. vaginata, but distinguishes by the lip and 2 triangular fleshy wings attached to the apex of column.
