There are eight types of vessel elements with different type of perforation plates in stout branch: one end scalarform type, the other simple type; only one end simple type; only one end scalarform type; both ends of the vessel element are simple perforation plate; both ends of the vessel element are scalarform perforation plate; three simple types; both ends of the vessel element are simple perforation plate, and the middle is scalarform type; a few scalarform types. Except the last type, stout branch have other seven types above. Stout branch's vessels are thin and short, but leptos branch's vessels are fat and long.

Key words: Magnolia biloba, leptos branch, stout branch, vessel element, simple perforation plate, scalarform perforation plate
