The tracheary elements in secondary xylems of Actaea asiatica root and rhizomes were observered with a scanning electron microscope and found to contain abundant types, which mainly included tracheids, tracheid-like vessels, fibriform vessels, and typical vessels. Of these types, the tracheids, tracheid-like vessels, fibriform vessels were first found. Scalariform perforation plates, reticulate perforation plates, mixed perforation plates and simple perforation plates were observed in the typical vessels and the reticulate perforation plates ,mixed perforation plates were first founded the lateral-wall perforation plates, multiple end walls and pit membrane vestige were also observed in the tracheary elements.
