Abstract
Through SEM observation, we found that there are vessels as well as tracheids in the secondary wood of Tetracentron sinense Oliv. The vessel elements are as narrow and as long as or slightly shorter than the tracheids and generally have 1 to 3 very long, or sometimes relatively short and oblique end-wall perforation plates; such perforation plates are also present on the lateralwalls. The perforation plates of the vessels include scalariform and reticulate-scalariform types, with various degrees of membrane remnants present in the end walls.
