Classification of Liriodendron in Magnoliaceae.

National second-class key protected wild plants (approved by the State Council 1999)

Magnoliaceae is an ancient angiosperm, which distributed in northern Europe, Greenland and Alaska with higher latitudes in the northern hemisphere from the middle Cretaceous to the early and middle Tertiary. In Cenozoic and Tertiary, it is widely distributed in Eurasia and North America. After the Quaternary Glacier, it only distributed in southern China and southeastern United States (both belong to the same species) and became relict plant.

Therefore, Liriodendron chinense and Liriodendron chinense are very rare and ancient tree species, which is of great significance to study the relationship between East Asian flora and North American flora, and to explore the geological and climate changes in the northern hemisphere.
