The micromorphology of vestured pits in 11 species of indigenous Yunnan hardwoods was observed using SEM. Considerable variation in the location and extent of vesturing and the morphology of vestures in the vessel pits is noted and illustrated with scanning electron micrographs. All the intervascular pits of the 11 species were vestured. They were divided into four types on the basis of the location and extent of vesturing within a pit. Vessel to ray and vessel to axial parenchyma pits were always found to be vestured in 7 species but to be both vestured and non-vestured in the remaining species. Vessel to fiber pits were vestured in the 5 species. Vestured fiber tracheid pits were found in only 2 species. Key words: SEM, vestured pit, Yunnan hardwoods, vessel wall
