Abstract: This paper illustrates that the Eastern part of Sichuan province and the Western part Hubei Province are concentrated areas of the majority of Paulownia species in accordance with the data of the palacobotany and the distribution conditions. These areas may be the asylum for Paulownia genus after the fourth glacial epoch. These areas as well as the middle and lower reaches of the Yangtze River are the distribution centre of Paulownia. This paper also discusion that Paulownia belongs to the East Asian flora of the palacotropical origin according to its morphological and ecological characteristics. It shows that Paulownia is of tropical and sub-tropical species. Consequently, the potentialities for developing Paulownia in the broad Southern regions in China are greater than the cultivated centre of Paulownia in the plains of the Yellow and Huai Rivers.
