Western Hupeh: Ichang, cultivated, alt. 40 m., April 1907 (No. 
3171,type). Fokien: without locality, Dunn's Exped., April to June 
1905 (Herb. Bot. Gard. Hongkong, No. 3369). 
Paulownia thyrsoidea seems most closely related to P. Fargesii Franchet which 
differs in its much larger, white or pale colored flowers with the tube of the corolla 
about 5 em. long, in its more elongated, entire leaves and in the smaller inflorescence.
